Living Visually Impaired in Prescott Arizona — The 2016 Story


If your vision is beyond correction by traditional medical and optical procedures, if you are anticipating this situation, or you are assisting someone like this, you need resources and training known as “Vision rehabilitation”.


Good news! Technology and well known practices offer affordable techniques to reduce many vision limitations to inconveniences if you’re willing to tackle the learning curve. Bad news! Prescott is limited in its access to rehabilitation personnel, awareness of possibilities, and diffusion of people who can help each other.


Below are resources collected by a Prescott resident who maintains vision loss coping skills after reaching legal blindness a decade ago. There’s plenty of room to improve the community resources. Please consider action, suggestions and collaboration for everybody losing vision in these days of abundant technology and information sharing.

What is Vision Rehabilitation


Useful techniques range from marking appliance settings by sticky dots through using a smart phone to read books, identify money denominations, and participate in social media. “Active Daily Living” refers to these sticky dot tricks and myriad organizational tasks formerly taken for granted. Serious safety concerns are addressed by “Orientation and Mobility Training” for climbing stairs, walking with the miraculous long white cane, and crossing streets. Gaining or maintaining computer communicationskills requires adapting to magnification or audio interaction or gesturing on a touch screen smart phone.


Sensitive interpersonal skills come into play when a conversation partner must be identified by voice or when sighted assistance must be requested. All these are conquered by learning and practice, leaving only the misery of transportation until the day of civilized public transit or safe, affordable driverless cars.

Where does one start recovering from vision loss?


When the page text becomes wiggly or haze surrounds you or objects jump into your path, eye doctors may help for a while, but there’s no miracle cure for effects of aging, sunlight, and genetics. Struggling to drive, read, walk, recognize faces, or see computer screens tell you it’s time to find vision rehabilitation. Medical interventions (except for cataract removal) rarely restore vision. Don’t deny, bargain, get angry, or become dependent when it’s time to learn new ways of doing things.


A great starting place is Macular Degeneration Support (mdsupport.org). You’ll find ongoing discussions about treatments, vitamins, iPads, good lamps, photography, travel, smart phones, and just about everything a Macular Degenerate lives with. We share secrets, such as the frequency of visual hallucinations called Charles Bonnet Syndrome. Guide books and tips abound. The community is international and multi-generational.


Another great resource is the “Eyes on Success” weekly podcast interviews with vision loss survivors, eyesight professionals, technologists, hobbyists, sportsters, and employed workers. A friendly pair of retired scientists in Rochester NY, one blind and one sighted, have compiled a library of easy listening MP3 files and show notes.

Where do I go for local help?


Locally, here are resources beyond the vision medical professionals who do not customarily offer vision rehabilitation as described above. Veterans have great residential training in Tucson. Students grow through school disability services and special education programs. People seeking jobs have state Department of Economic Services special programs and assistance to work. Otherwise retired people must generally develop and implement their own rehabilitation programs.



  1. The ‘People Who Care’ nonprofit offers “Confident Living” introductions to topics in Vision Rehabilitation and Causes of Vision Loss. Limited transportation and other elder support services are also available. Six-week seminars are presented when funding is available.
  2. Georgeanne Hanna is a contact with and certified rehabilitation contractor for state services that also assist retired individuals. Her phone is 928-775-5857. Watch for Public Service Announcements. Orientation and mobility trainers can be imported at state expense upon request.
  3. The Disability Empowerment Center (formerly New Horizons Independent Living center) provides independent living services for people with various disabilities, and a transportation system based in Prescott Valley. Call and ask whether vision rehabilitation services are currently available.
  4. Yavapai Library Network sites have assistive computers for people who know how to use magnification and audio assistance. Contacts are available for the National Library service “talking books” program.
  5. YC OLLI (Osher Lifelong Learning Institute) offers occasional workshops on vision and hearing loss adaptation.
  6. Prescott Fine Arts Theater honors requests for front row seating for visually impaired people and companions.
  7. Lions clubs underwrite medical and optical services for low income persons and occasional publicized events. Clarification of their services would be appreciated in the comments of this website, especially to identify matches with needs expressed here.
  8. Warning!!! Former organizations now defunct include: Northern Arizona Vision and Hearing Loss, “old blind center”, Yavapai Association for Blind and Visually Impaired (YABVI), “new blind center”. Check out carefully Daily Courier articles for dates referring to services gone from the troubled trail of Prescott vision supporters.

In summary, People Who Care Confident Living Seminars and state DES rehabilitation coordinators are the primary currently active resources. A mobile person losing vision should also consider relocating to gain a full multi-month training program from a facility such as Southern Arizona Association for Visually Impaired.

What help is available from government?


  • AZ Department of Economic Services supports a local vision rehabilitation professional (see above), special services for vocational training, and limited assistive technology. An online directory is available.
  • In 2014 Prescott established Disability and Accessibility coordination mandated by the 1990 American Disabilities Act (A.D.A). Call the city information line or http://www.prescott-az.gov/accessibility/. The federal ADA.gov website expands on citizen rights, organization responsibilities, and procedures for grievance.


    Many cities have a Disability Services Coordination council based in the Mayor’s office, alas not Prescott, but maybe in Prescott Valley. Audio alerts for street crossing are available only on Willow Creed Road near Embry-Riddle but not downtown. Sidewalk barriers, icy patches, overhanging branches, and unsafe construction should be reported to City Streets and Code Enforcement (they do respond). Visitors to downtown Prescott should not expect comfortable, safe walking conditions.

  • with A.D.A. enforcement, airlines, banks, and hospitals have trained personnel for providing equitable services. PHX airport provides walking guides through TSA to your gate (tell before checking in). Notable within Prescott are bank “talking tellers” for automated cash withdrawal (e.g. Chase Bank). Checkout devices at stores are now equipped for accessibility and privacy, e.g. typing in a PIN, but may not be enabled or known to checkout personnel.
  • social Security offers documents and transmittals in electronic formats on CD.

What do blindness support organizations offer?


The following groups are knowledgeable about all aspects of vision loss and advocate for improvements that benefit people with disabilities. Organizations that accept charity contributions are not necessarily well informed about Active Daily Living, Orientation and Mobility, assistive technology, the A.D.A, or the interface between medical and social service systems (but they should be). “Helping the visually impaired” requires education, awareness of needs, and accountability.


  • The American Council for the Blind (ACB) and National Federation of the Blind (NFB) advocate and educate on blindness issues that benefit people with all kinds of vision loss. State affiliates hold annual conferences and support local chapters (but not currently in Prescott).
  • The American Federation for the Blind (AFB) has special websites for seniors and is affiliated with the Vision Aware service. A monthly newsletter evaluates technology
  • MDSupport.org specializes in macular degeneration with myriad free downloadable guides and an ongoing support mailing list.
  • Books and newspapers are available from Bookshare.org, with a library of over 400,000 fiction/nonfiction, adult/adolescent volumes readable on the website or downloadable to book readers. The NFB NewsLine offers national newspapers and magazines in various formats and reading services, available also through BookShare. National Library (NLS) provides narrated books played on free) devices.

How about technology?


  • PC and Mac computers have built-in magnification and voice support. For Mac, VoiceOver is a click away while for PC a free NVDA package is easily installed. Various $1000 commercial products offer versatile magnification and audio with support and training. These “screen readers” enable a synthetic voice to speak web pages, documents, and buttons or typing. The technology is great, but the learning curve is steep and trainers are scarce.
  • Elegant hand-held devices can read books from NLS or Bookshare, notably Victor Reader Stream and BookSense. Amazon Kindle and Nook devices are not usable without sighted assistance.
  • The smart phone has put mainstream devices into the hands of people without full vision but with sufficient hearing. The iPhone, iPad, and iPod Touch have Voice Over built in to read buttons as fingers glide across the screen as well as text in mail and web pages. Book reader apps from Bookshare, Apple, NLS, Amazon enable downloading and listening to books, magazines, and documents.

  • Smart phone apps provide walking navigation, location awareness, remote identification of photographed objects, reading money, and other assistance. Many games and apps are fully accessible. Speech recognition increasingly replaces keyboarding. Apple devices (iPhone, iPad, iPod Touch) are fully accessible by voice (use Triple Click Home to start). Android devices lag Apple in both capabilities and training, varying across models and manufacturers. Verizon and Apple store personnel can assist in turning on these devices but only practice will determine whether they meet vision needs.


  • The blindness communities maintain a “Internet radio network” of interviews, demonstrations, and advice on all topics related to vision loss and especially technology. Accessibleworld.org, EyesOnSuccess.net, and Hadley.edu have highly informative weekly updates. These are MP3 files for subscription and downloading as podcasts via iTunes or podcatcher apps.
  • Hand-held readers also serve as recorders for presentations, memos, and bookmarks. Some also provide radios with audible controls.
  • Apps can remotely recognize and label record contents of files and food cans. Color identifiers, GPS systems, and talking thermostats exist to overcome daily eye sight annoyances. The coming Internet of Things offers in-home devices that recognize speech, read out device information, and operate remotely. Be sure you understand the surveillance capabilities of such devices as well as how failures can lock you out or inadvertently activate other devices.

  • Twitter social media is a river of news about technology and blindness under the keyword #accessibility and people like slger123 and all major vision-related organizations and federal agencies.

Where can I get more information on vision rehabilitation in the Prescott region?


This web page is your current best bet for information. Its author is a legally blind technologist. She survived the sparse services available in Prescott by seeking resources for self-rehabilitation. She has attended national and state assistive technology exhibitions and visited vision rehabilitation centers in Tucson and San Diego. She’s a user of assistive technologies and a constant tracker of external services. Ask her anything about vision rehabilitation and she’ll find an answer.


Please add comments with additional services, corrections, or opinions. Anyone interested in taking over this web page and keeping it up to date is welcome to the information compiled so far.


Isn’t it time Prescott had full service vision rehabilitation for retired people with vision loss? Following the MDSupport motto “No one should leave an eye doctor’s office thinking their situation is hopeless”, vision loss is a journey of learning and adaptation and challenges that build on established rehabilitation practices and abundant technologies. Why can’t Central Yavapai have a branch of such a facility? Advocacy needed!!!

Warnings About Web Misinformation


  • Web searches in Google, DuckDuckGo, Bing often link to misleading or outdated web pages. Sometimes links go to local white/yellow page directories driven by advertising.

  • The following organizations are defunct: Northern Arizona Vision and Hearing Loss Center; Yavapai Blind Center; YABVI Blind Center;; and related terms. There is no blind center on Washington Street, vacated in 2007. The phone number 928-778-0055 is disconnected. If you receive a brochure or read an article about this location, facility, or phone number, please correct the mis-informant. YABVI (Yavapai Association for Blind and Visually Impaired) appears to be a restructuring of a previous organization, now managed funds by a group of eye doctors.

  • No attempt is made here to assure accessibility of web sites beyond ascertaining content using Firefox with the NVDA screen reader. Some resources use PDF documents difficult to use with a screen reader.

  • Resources here focus on “vision rehabilitation” rather than medical treatments typically billed to Medicare or insurance. Vision Rehabilitation includes: Orientation and Mobility Training, walking with a long white cane and safely crossing streets; Active Daily Living, tricks and techniques for optimizing remaining vision in everyday life; reading newspapers and books; and using technology by magnification or voice interaction.

Sandwich Board Signs Are Dangerous!

January 15, 2016

The Costs of Sandwich Board Advertising Signs


  1. Are wooden sandwich board signs dangerous? Are they safe when placed according to city code?
  2. Who pays if there’s an accident between a pedestrian and a sign? How much liability insurance is required of sign owners? How much liability insurance is apportioned to pedestrian accidents within the city budget?
  3. What is the cost/benefit to merchants? citizens? tourists?
    What is the risk/benefit to merchants? citizens? tourists?


Submit your answers below:

Accident report: Sandwich Board Sign Injures Pedestrians on Downtown Prescott Street, October 14 2016

Deceased was walking along Whiskey Way on a nominal weather day using her mobility cane. A careless runner pushed through a crowd of children leaving their school. Several people bumped into each other, with a few falling down.


Deceased attempted to step aside while untangling her cane from a sandwich board advertising sign. Such open wooden frame barriers are positioned approximately every 10 feet. Other pedestrians were also injured as signs broke apart or flattened on the sidewalk. A cascade of signs and bodies caused many additional falls.


Deceased struck her head on a sharp sign edge and a second time as she fell onto the street, unconscious.


Since the signs that caused injuries were legal under the city’s ordinance, no citations were issued. Liability remains to be determined. Lawsuits are expected against the city, merchants, and sign distributors. The careless runner has not been located, probably ducking into a local bar after the chaos, perhaps not even realizing its cause.


Let’s prevent this accident from happening! Any pedestrian is vulnerable to unsafe signage, anywhere. And, about those saw horses and barriers that warn of unsafe pavement, they’re dangerous, too! Tell Prescott City Council to ban advertising sidewalk signs and fix sidewalks that need fixing.


Will Computer Science Meet accessibility in 2011?

January 18, 2011


I’m a legally blind retired computer scientist. As I gained proficiency with assistive technology for reading, writing, and communicating, I faced similar costs, barriers, grievances, and coping challenges as thousands of other computer adept late career people. However, I also take a keen interest in effectiveness and usability of my access tools and the media they work upon as a total system for processing information in our marvelously plastic brains. And, as former educator, researcher, and manager, I look upon my profession as contributors to both sides of the problem and solution arenas acting under broader social forces from government, demographics, and mainstream technology industries.


May I share my unique experience with you? Here’s my take on the current state of computer science (CompSci) related to Persons with disabilities (PwD)in general and the specific opportunities for visually impaired persons. Assistive technology refers to software like screen readers that use text to speech and keyboard focus interactions with operating systems, applications, and web pages. Accessibility is a matter of degree to which the applications, OS, and web sites support assistive technology. to achieve the same performance and satisfaction as all other users.

responsibilities, accountability, openness, and Opportunities for CompSci


are educational institutions now, in 2011, ready to embrace disability civil rights? Is the academic computing field prepared to integrate advances from the separated assistive technology industry and the generation of students raised with strong but different skill sets? Can CompSci meet its aspirations of providing the 4th R of education for everybody? Will there be movement to re-mediate decades of deficient designs of web information management systems and individual documents? where does CompSci and information technology fit into this solution, or problem, space?

basic accountability as an academic discipline


Like all educational fields that use web resources to assist education, the CompSci and IT fields are clearly responsible for adhering to standards that mitigate barriers for people with disabilities using available assistive technology. Especially where costs of access technology and special skills have been attained through rehabilitation resources or even individual investments, this is immediately a matter of jobs for PwD. Moreover, there are ripple effects for all intermittently or eventually disabled persons or caretakers, or tax payers, and that is everybody several times over.


Have our fields done well so far? No, as shown by flaws revealed traversing the 2010 Computer Science Education week and partner websites (see data below). These are rife with stumbling blocks, and generally exhibiting indifference to established design and usability practices. Barriers are unnecessarily erected, and unfortunate messages of ignorance and indifference indicate a field not so much up with trends in user oriented communication. or even acknowledging sensory differences in users.

domain responsibility of the CompSci field

CompSci and IT bear the additional responsibility of producing the tools, languages, and patterns; the programmers, designers, and testers; the processes, quality assessments, and design strategies; interfaces, interaction models, and transactions; the books, published articles, and motivations; and so on, that underlay the capabilities for educational institutions to meet their basic accountability.

>
Further CompSci responsibilities are the development of cultures where people with disabilities exhibit their skills and tools to demonstrate how well they can produce software and hardware products and artifacts. Beyond Cultural integration is the need for domain knowledge, e.g. how screen readers and caption systems work and how artifacts must be designed for smooth operation by persons using assistive technology.


CompSci has often promoted pedagogical tools like Alice and scratch that explicitly bar people with certain disabilities getting equal footholds in and excitement about computing. Nevertheless, many people have not only become high functioning but also innovative regarding access technology, including the very products I’m using to write this article. A community of computing oriented professionals have banded together to produce the aforementioned standards, tools, processes, and businesses that await adoption by CompSci and IT.

Computational thinking opportunities await CompSci


In fact, the above strengths and weaknesses of the social motivation for overcoming limits for PwD are truly, really, beautifully illustrative of computational thinking. The widely used WCAG standards are a fledgling “science of accessibility” with tested hypotheses, guidelines,, terminology, and a blogging trail of intellectual progress. Good web pages are all about semantics: markup, logical structure, sound relationships (in a database sense), and progressive enhancement design to transform semantics with syntactic elements like color and graphics. The essence of accessibility is support for multiple representations where access tech supplements or replaces sensory limits. Abstraction, semantics, representations, implementations, relationships, … are the sound principles for achieving the technical aspects of basic accountability and additional responsibilities of computing fields.


Hey, take the challenge! What should CompSci and IT do?

  1. clean up our websites, a good goal for Cs education week 2011. Read the standards, use guidelines and tools to re-mediate and assess quality, then do the work. With remediation of technical zits will come a better understanding of the computational thinking issues that should lead to improved designs.
  2. Take responsibility for explaining disabilities and accessibility to educational colleagues. Incorporate local disability service professionals and
    enlist the fear and concerns of university management to assure resources.

  3. audit all pedagogical tools and artifacts and label each for sensory and disability limitations. Then progress toward the better products available while applying computational thinking for more universal representations.
  4. Use the competitive, exciting advances of tablets, smart phones, text to speech, and accessible apps to motivate and explain both how accessibility works and why it matters in our economy. Just open up the hood under the accessibility options and check out the high performing speech interfaces.
  5. Learn to talk with persons with disabilities about their
    needs, high functioning skills, innovative tools, and culture.

  6. Do not feel bad about lack of experience or past mistakes. We are all overdue with a dose of karma, such as this writer who cannot use or maintain security education applets I developed five years ago. Ouch!

.


Overall, let’s open up a new field of computing, pull publications out of the ACM pay wall, and lead the way through computational thinking.


why not?

Issues, evidence, and epiphanies

are the feds really coming after universities for inaccessibility?


The Obama administration departments of Justice and department of education Office of civil rights have certainly shown signs of action backed up by White House ceremonies and initiatives:


On the positive side, California state University system is often praised for its improvements. Sadly, a funded study of analysis of university web accessibility is hidden in an obscure journal.


If all this comes to fruition right under the noses of congress, regulatory and advocacy will open many doors for computing professionals with a bent toward social entrepreneurship and intriguing technology advances. By the way, the professional accessibility virtual water cooler spreads daily updates on Twitter .

What will happen if universities are forcefully or voluntarily driven into accessibility? We may know by 2012.

why hasn’t accessibility and assistive technology taken hold in computing research and education, ?


As a former educator, I’ll take the all purpose route of blaming the textbooks? One form of blame is the presentation of content as in printed tomes, derived from WORD documents, spruced up by publishers, and embellished with instructor power points all performed without consideration for readability by print disabled students. This forces, I’m not kidding, hundreds of pages to be scanned into electronic forms where most original MS-WORD structure is lost, i.e. hours of labor in an error prone incomplete reverse engineering process.

How dumb is that?well, nationally, this problem is being rectified by bookshare under a department of education contract to adapt, just once in an industrialized manner, many college and K-12 textbooks. However, there isn’t a similar well known cooperative effort specializing in computing texts, or efforts by publishers except for Oreilly Media contributions of its electronic versions directly to bookshare.


Now, consider textbook content itself. Are there any, like more than 0, standard computing texts that contain chapters and exercises on assistive technology and accessibility as recommended in standards and produced by specialized branches of software and publishing industries? Please comment any examples.


the root of all evil in textbooks goes back to curricula accreditation. Omitted there, and frozen into practice, accessibility principles are instead forced into industry workshops, such as Knowbility Access U and Open Web Education Alliance. This further differentiates career paths with web development considered a craft, combining touchy feebly communication, advertising fodder, turnkey content management systems, and a steady flow of freelance or in house jobs open to lesser educated mortals.


The irony is that web accessibility is one of the best exemplars of “computational thinking” that has driven some higher echelons of CompSci leaders. See my 2009 post on many ways accessibility and assistive tech put computational thinking in action for pedagogical practices.

really? is the W3C nurturing a “science of accessibility”?


Read the W3C Web Content Accessibility Guide 2.0 and “Universal Design for Web Applications” by Wendy Chisholm and Matt May for lively explanations and motivation for the WCAG standards.


There’s an amazing amount of thought hammered into shape and utility in these guidelines and scenarios on the w3C web site. Rather than tons of funded research projects to identify hypotheses and perform experiments and build prototypes, the standards bodies combine experiences from developers, authors, consultants, and gadflies who really care about their subject. social and technical consequences. Fights and personalities drive discussions toward articulation and analysis that don’t come out looking like ACM portal abstracts. Nevertheless, pick any recommended practice, e.g. headings and logical structure in web pages, and you’ll find rationale, practical hedges for difficulties, and the basis for better controlled and more academically rigorous investigations.


As for the actual academic research communities, there’s a strange legacy of publication practices that make it difficult to track the field. Conference papers disappear behind the ACM Digital Library Portal pay wall. Institutional and individual members of ACM have access that people like this retired researcher have to fork over $200 to reach. Even paying the ransom isn’t enough, as I found it exceedingly difficult to negotiate the search interface in the 2008 time frame, and without response to requests for assistance. In other words, the publication pay wall is an inhibitor to the spread of insight on accessibility from perfectly serious and hard working researchers. How silly is that?


The notable exception I track is the work of professor Richard Ladner at U. Washington research and outreach and his prolific junior colleague Jeffrey bigham, now at U. Rochester. WebInsight project publications are available as readable PDF’s organized well by topics and authors that offer the bulk of their funded research.. These publishable fundable research results are intelligible, related to the standards versions of their science, and especially interesting for a user of the technology attracted to computational thinking, i.e. me. But then the papers reference too often into the ACM portal black hole. Wouldn’t the field progress more rapidly if more people could read such publicly funded publications and appreciate the experimental models being applied?


One additional topic I tracked was an award winning paper mentioned in Professor bigham’s blog on web research, namely the collaborative accessibility project at IBM Japan. However, the best I could find was a useful Youtube video on “social accessibility”. Indeed, with additional perspectives from the grass roots operational social accessibility projects webvism community tagging and solana for cracking the evil CAPTCHA barriers facing visually impaired web users. Indeed, find screen reader and accessibility videos on Youtube including Easy Youtube since Youtube itself is marginally accessible.


another interesting area is accessible apps for apple and android mobile products. There are important engineering lessons here regarding accessibility integration into the architecture, with apple doing it well, Google trying to paste on its talkback capability, and Microsoft admitting it blew off accessibility in its win 7 phones. Google Android accessibility is dubbed the “Model T Syndrome” for not applying state of the art engineering techniques, expecting visually impaired consumers to wait years for reasonable functionality and usability.


Finally, for the serious minded computer theory connection, visit the IBM researcher and leading accessibility guru Jim Thatcher articles on practical standards in business as applied to Amazon.com, Target.com, and many .gov websites. This wealth of robust reasoning and decades of experience are truly awesome.

What’ is the evidence for bad accessibility practice in the computing field?


Here is a test you can perform yourself.


Start the CSED Week test in Web Aim WAVE analyzer. Yes, click that link and now you’ve been seduced into web page testing! Now, look for the link to Partners, click and see the errors there. Keep going for the partner websites, opening and analyzing each web site. Keep going and you will be amazed at the WAVE complaints as the page structures are revealed in their semantic nakedness.


Lots of errors, right??? Let me explain how the errors affect my reading using an interactive access tech “screen reader”, illustrated in recordings in the 2009 post.

  1. The “missing ALT description” error tells me the web site developers have no clue about accessibility, ignoring the most basic rule. Visually impaired people cannot know what’s in your graphic, why it’s there,if it is decorative or meaningful in context.
  2. At the higher level of page structure are errors in omitted headings, irregular heading levels, and uninformative headings. The basic problem for someone visually impaired is building a reliable map of a page to transform from a linear search by laboriously tabbing from one HTML element to another. The outline tells me quickly what’s on the page, just like the outline of any well written document. Rarely do I find a web page from a CompSci organization with a good outline, often omitting headings entirely. Another indicator is irregular headings, like H4-H1-H3 which usually indicate confusion among semantics of headers and font-style presentation issues better handled by style sheets.
  3. Unlabelled form elements can be a show stopper when leading a person and screen reader through a donation or purchase or registration form. The proper HTML has an explicit corresponded between label and element, call, duh, “Label”. Without labels, the user just hears “edit box” rather than “first name edit box”. Forms are really complex , often associated with transaction timeouts and monumental headaches locating and fixing errors. Again, there are good rules for creating usable forms, which the unlabelled form element error tells me the developer has ignored. Do they want my business?

  4. Standalone link names are important for, like headings, a link abstraction allows rapidly skimming for general context and specific refinements.”Click here”, “here”, “read more”, and “learn more” require the screen reader user to search around for context. See post “I don’t want to click here” for a humorous take on this annoying practice.
    <

Webaxe guide to introductions to accessibility and its demo podcasts is a good place to start and also entertaining. WebAim Web Accessibility in Mind also offers an annual empirical analysis of screen reader use and many checklists and guidelines. One caveat is that WAVE, although free and easy, is susceptible to flaws of any static analyzer with false hits, cascading errors, and interpretation of results. However, our tests show that it readily exposes often embarrassing mistakes just waiting for correction. My favorite was a major CompSci blog with hidden text offering Viagra remedies.


While many of these complaints relate primarily to technical communication, there are true design problems related to search tasks, as on the ACM Digital Library, and on large multi-organizational websites like universities. Beyond accessibility, as in supporting technology, are issues of bandwidth limitations, small screen mo vile devices, and user choices on browser script security. While not formalized as in “structured programming” or “object-oriented design”, the recommended engineering practice is “progressive enhancement”, starting from a purely semantic page that covers the basic content and separates presentation layers which a browser can strip away to assure the content is preserved in many contexts. It cannot be emphasized too much: the person using a screen reader is working directly with the semantic content provided by the developer. Designer focus on color, fonts, graphics, and interactivity are truly only “in the eyes of the sighted reader” and may add to but should not obscure the essential page content. and use cases. In other words, the analyses provided by tools like WebAim WAVE and even more important, the mental model in the person using a screen reader provide a favor to page designers by pointing out flaws.

And, is there any good news?


Definitely,when cultural divisions are bypassed, are growing assemblage of tools that enable someone losing vision to maintain their computer skills, provided they can access the training and guides to re-build their own environment. Admittedly, regaining capabilities after vision loss requires months of hard work, willingness to learn new approaches, and acceptance of major life changes.

  • AThe free, powerful, open source screen reader NVDA (NonVisual desktop access) competes with established $1000 pricey products on Windows platforms. I truly enjoy, and donate to, the mailing list of international users who daily test and share advice on this Australian generated project. Its developers are blind, primarily using python. These guys deserve a major computing award for their global contributions and professionalism in their twenty-something age ranges.
  • The miracle of Text to Speech that activates the hearing sense into an alternative channel into our brains where reading actually takes place. While older people may take more time to rewire their brains after vision loss,it’s truly remarkable that vision can be so minimalist in computer usage, provided accessibility is engineered into our software and information sources. Now, we’re poised to take on the challenge of “information visualization without vision”, seriously a cognitive and technological adventure in literacy and openness.
  • Bookshare and NFB News Line downloadable a alternative for print disabled services that brings literally 1000s of great books and daily newspapers to our fingertips in wireless seconds. Never did I imagine I could have such a great store of information to support my retirement book club, lifelong learning, and social entrepreneurship activities period. Materials are read by synthetic speech from DAISY, an XML based, international standard for audio and text content.
  • Levelstar Icon Mobile Manager and Docking Station, designed and distributed by a blind engineer, that streamlines my access to Bookshare, NewsLine, Twitter, email, and RSS. Most sighted, and now blind, people will enjoy an immense number of accessible iPad apps, a direction I’ll soon be taking myself.But the Icon sets a high bar of throughput I don’t expect to find on any other device by avoiding screens, using spoken menus and text reading. Another award worthy young technologist for CompSci to learn from.The implementation software for this handheld LINUX box is python and sqlite.
  • The #a11y Twitter community of accessibility gurus, blindness advocates,normal blind working folks, and inspiring authors lifts me up every day with humor and an unbelievable syllabus of linked readings. I never expected to find such a “School of Twitter” in social media that could fill my local personal and professional void. I especially value AccessibleTwitter website and demonstration for its common sense, ease of use, and challenge to the big clunky Twitter, which is, of course, the data source and API.

  • I’m also grateful for professional opportunities to potentially influence the direction of computing through the CMD-IT Center for Minorities and Disabilities in ITan, its Board of Advisers, and energetic organizer. I’ve written two other posts input to an NSF Task Force on CyberLearning, and hopefully await an insightful report.
  • Close to home, I appreciate the opportunity to connect with a few local disability professionals and volunteer groups. I’ve seen first hand how a broken rehab system requires enormous cooperation and energy to bring to ever more baby boomers losing vision the tools and experience I managed to find for myself. For all the $$$ spent on research, the chain of referrals and services beyond the medical plateau leaves so many of us just hanging on precariously while trying to find our ways through the inevitable grieving and depression cycles. It shouldn’t be this way in a
    wealthy world, requiring not charity but rather planned delivery of existing resources, as related in Jane Brody’s NYTimes articles on vision loss.

The 2011 CompSci Meets Accessibility Manifesto


And that latter point is where my disappointment with the handling of assistive technology and accessibility in computing has lead me to put considerable effort into writing up this critique. We just have to do better in accountability within institutions, domain responsibility for our professionals, and awareness of the depth of effectiveness of our computational thinking methods. Thousands of jobs depend directly on our outcomes for accessibility and quality computing products, plus centuries of better quality of life for everyone sooner or later. Let’s make accessibility meet computer science professionally in 2011.


We’re now at a teachable moment for assistive tech and accessibility in computing education. Everybody has the basic functions in their hands, literally, and for free. Windows users can download capable free open source NVDA screen reader and try testing web pages. Android and IOs users turn on their text to speech and learn credible NonVisual manners of using myriad interesting and useful apps. Come on, anybody can learn to work like a low vision person so the days of descending into the exorbitantly expensive blind ghetto for access tech is over. Anybody from now on who produces inaccessible pedagogical products or sloppy web pages is out of excuses. Your artifacts are testable, the testing tools are available, the engineering practices are wedded with the science of accessibility in standards. and people with sensory limitations like my hazy vision have those access tools at their fingertips, skilled and raring to use products made for mainstream but accessible if properly designed. So, failure to step up to this challenge and do the right thing, which really isn’t so hard and actually is good for business, is a choice of accountability, responsibility, and opportunity.

What Vision Losers Ask in Searches

April 19, 2010

Personal Themes: Planning, mobility, advocacy, citizenship


In the preceding post on search terms about technology, I recapped some lessons about technology assisting me as a Vision Loser: the wonderful free NVDA scrreen reader; gaining independence using a talking ATM; some technicalities of working with the generally usable WordPress platform; Applemania for assistive technology; and the over-arching theme of TTS, i.e. text-to-speech with synthetic voices. The terms people use to reach my blog expand my range of topics even if I have to make up an interpretation for the searcher’s goal. This post covers more personal than technological topics.

Terms and Basics: “Legally blind, disability, and personal meaning”

Search terms used to reach this blog

  • creative activities for the legally blind
  • what is print-disabled.
  • can a legally blind person join the navy
  • legally blind disability
  • culture of disability
  • identity after disability
  • who are the legally blind non-readers?
  • are legally blind people fully blind
  • jobs for us citizen for partially blind
  • forms for legally blind declaration
  • adversity as change in disabilities
  • resilience partially sighted
  • disability resilience visual impairment
  • orientation and mobility trainer
  • the use of technology and loss of eyesight
  • declaration of legally blind

VisionAware glossary of vision-related terms offers one framework. This topic is certainly a matter of curiosity for both sighted and Vision Losers like me. Frankly, I am rather indifferent to precise terms and refer to myself as blind, partially sighted, visually impaired, disabled, etc. according to how I think the person I’m communicating with will understand and react. More important, I believe, is that the Vision Loser can be matter of fact and comfortable about the situation. Of course, practically speaking, there is that extra box to check on tax forms, that ID card or driver’s license card, the signature line you’re asked for, and many other details of personal and financial transactions. To my knowledge, there is no moment you get a stamp of “legally blind” but rather a process lets you know it is happening. In fact, vision may fluctuate up and down along scales of acuity and bredth of field that was for years my diagnosis of “stable, but precarious”. In fact, I walked through TSA checkpoints with a white cane in one hand and a still valid driver’s license for ID and even once rented a car from Hertz when my companion couldn’t get a debit card approval. No one ever asks “hey, are you legal?” except in bars. And often the situation itself such as bright lights may define whether your sight is functionally useful. What I find more interesting and challenging is planning and navigating the rehab maze. That will be a future post. For now, the above terms just identify some of the ways people look for information.

  • no sidewalks for the disabled
  • measuring for white cane
  • using an id cane
  • emotional response to using a mobility cane
  • partially sighted use of white stick
  • white cane technologies

Terminology: identity cane in U.S. called symbol cane in U.K. and differs from ‘long cane’ used for practical mobility. Colors also may differ internationally, white in the U.S.


Back when I was starting to require mobility assistance, I wrote about the values of using an Identity Cane. This instrument was a puny stick valuable for poking around and showing others of my disability, but wasn’t functionally useful for walking or climbing stairs safely. Due to the sorry state of social services in the U.S., notably retirement-focused Arizona, it took a long search, months after I really needed help, to find an OMT (Orientation and Mobility Trainer). Gifted from the state with a $35 sturdier cane matched to my height and walking style, I gratefully received a few lessons in waving the cane and negotiating street crossings.

Here’s the answer to the basic question. You use the cane either tapping or sweeping ahead to tell of rough surfaces, dips, curbs rocks, people’s feet, etc. Meantime, using residual vision, you watch for upper body hazards, like trees, mailboxes, street signs, elbows, etc. Climbing stairs, I use the cane to tap each step then sweep when I think it’s a landing, with bottom steps being the most treacherous. Crossing streets requires far more strategies of listening for and watching turners and signal timings, with the cane displayed or waved to attract drivers’ attention. That
is how I do it, probably not completely according to rules, but I haven’t been to the Emergency room in years. Note: as to measurements, this does require the help of an OMT person watching you and your own personal experience with a length that feels comfortable. It’s a matter of a few inches more or less. Furthermore, at first your arm gets tired so a few trial lengths may be affected. My OMT gave me two specific useful pieces of advice: (1) avoiding a nasty step on the path to my lifelong learning classes and (2) make yourself “big” and noticeable at intersections.


My current problem is actually when people try to help and distract me from the synchrony and concentration of using the cane. Often companion walkers get in a hurry or talking and tell me something like ‘5 steps’ when there are are 4 or 6 or, never matter, let me take the steps at my own pace and style. Most of this training is simple but just requires someone to nudge you out and help build confidence, then practice and learning one’s own mistakes and recovery strategies. This is a difficult interpersonal issue as to how to refuse help as well as when and how to ask for assistance.


Another concern is becoming a hazard myself, like tripping a shopper looking at grocery shelves. Or tangling canes when walking with someone with their own mobility difficulties. And, I’m currently having a real phobia for street crossing, with too many instances of drivers entering the crosswalk a few feet away and just plain realization of the dangers of inattentive drivers in a hurry. Now, we need a national law to install yet another electronic gadget in cars, receivers from a cane telling drivers we’re around — like your GPS might say ;blind pedestrian at corner waiting to cross Willow Creek. Please wait’.

Accessible websites and advocacy

Terms asking about accessibility

  • “heading list” + accessibility
  • computer curb cuts wikipedia
  • bad accessibility websites
  • page layout of whitehouse.gov
  • sites with bad accessibility
  • image alt tag checker
  • how do i find my alt tags for my picture
  • headings accessibility test
  • universal design for web applications we
  • pdf crippled
  • Google book search accessibility


It comes with the territory that something in society makes a Vision Loser feel like a real loser, for avoidable reasons. Those ‘advocacy juices’ start to flow, you learn why social practices are so harmful, find and apply constructive advice, rationalize compromises, use mistakes as educational opportunities, and generally contribute to the betterment of society. Well, that would certainly be nice but if it were that easy a few active complainers could clean up the messes in society that hamper our ability to operate like everybody else. For me, with my lifelong exposure to the Internet, web accessibility is a perfect advocacy focus. For others, safety or OMT or low tech devices or public transit or rehab or costs might blend professional backgrounds and advocacy missions.


This is my major criticism of inaccessible web sites. If only headings were used to organize and label page parts, screen reader capability to navigate by headings could be fully utilized. Literally hours of wasted time extracting mental maps of pages or tabbing around the wrong lists could be avoided. Indeed, I think failure to use headings is a root cause of many accessibility problems, e.g. lists of unrelated links, maintenance messes, … When I see a page using an ‘h4’ only, I know page authors don’t understand separation of content and presentation nor are they using established progressive enhancement engineering processes. My recommendation in my complaint to site owners is to attend accessibility courses, read myriad blog posts, track #accessibility and #a11y on Twitter, and read Chisholm and Mays ‘Universal Design for Web Applications’. Other culprits, however, are web page editing and content management systems that, hopefully, will soon be superseded by projects like Drupal with accessibility as an important selling point. H1, H2, H3,… is so fundamentally sound for both writing and reading web pages.

Citizenship and Electronic Voting

Terms

  • the nitty gritty of electronic voting

I wrote about my experiences in the 2008 primary and national elections with a generally favorable impression of the usability of the voting tablet. However, voices sped up or slowed down and I had no way of validating the printed output. The voting system vendor Premiere Election Systems is now defunct, with a rather poor history of counting accuracy complaints. Who knows what’s next for this autumn’s national and local elections. It would be great to have a more common interface among similar devices: voting, ATM, store check-out, remote controls, thermostats,… Common functions include: navigation, voice control, selection, confirm/cancel, etc. for users and various administrative setup of ballots, etc. Foremost is that ‘all things should talk to users’ and eventually hold on-board speakable manuals and environmental information. Just
wishing…


My main message on citizenship is that vision loss should not be a disable for citizenship but we have to be take the initiative to make the voting experience productive. For some people, independence and privacy are not big issues, so taking a sighted person to mark you ballot feels fine. For others, like me, I want to stretch the system and use voting as a teachable moment for family, friends, and community. That’s a tall order but legally mandated. For U.S. citizens now is the time to find out how you can vote in the upcoming elections, like calling or visiting local election boards. This was a good experience for me and even helped the election officers to watch me at work.

Remembering Sputnik: Just a memoir moment

This topic has nothing to do with vision loss or accessibility but rather is a memoir and personal history of Sputnik. For many scientists and technologists in our 50’s and 60’s Sputnik was a notable national event (1957) that precipitated funding for and attention toward math and science education. Summer institutes for high school students and teachers, fellowships, and, drum roll, DARPA and the advent of the Internet. Our Social Media class has proposed lifelong learning activities where we collect, post, and record our experiences and related materials for our progeny and educational systems. Amazingly, most of us had little American history covering WWII, Cold War, etc. just lived through it haphazardly. Today’s students also don’t get much modern history, so our event recollections, like the NPR story Corp project, might provide legacies and primary materials.

Thanks for asking!!

Search terms provide really useful feedback.

Vision What do Vision Losers want to know about technology?

April 5, 2010


Hey, I’ve been off on a tangent from writing about adjusting to vision loss rather on a rant about and praise for website accessibility. Also absorbing my blogging efforts was a 2nd run of Sharing and Learning on the Social Web, a lifelong learning course. My main personal tutors remain the wise people of #a11y on Twitter and their endless supply of illuminating blog posts and opinions. You can track my fluctuating interests and activities on Twitter @slger123.

To get back in action on this blog, I thought the WordPress stat search terms might translate into a sort of FAQ or update on what I’ve learned recently. Below are subtopics suggested by my interpretations of the terms people used to reach this blog. Often inaccurately, some people searching for tidbits on movies or books called ‘twilight’ might be surprised to read a review of the memories of an elder gent battling macular degeneration in the 1980s. Too bad, but there are also people searching for personal experience losing vision and on technology for overcoming limitations of vision loss. These folks are my target audience who might benefit from my ramblings and research. By the way, comments or guest posts would be very welcome..


This post focuses on technology while the next post addresses more personal and social issues.

NVDA screen reader and its voices

    Specific terms on NVDA reaching this blog:

  • NVDA accessibility review
  • voices for nvda
  • nvda windows screen reader+festival tts 1
  • videos of non visual desktop access
  • lag in screen reader speaking keys
  • nvda education accessibility

Terminology: screen reader software provides audio feedback by synthetic voice to users operating primarily on a keyboard, announcing events, listing menus, and reading globs of text.


How is NVDA progressing as a tool for Vision Losers?
Very well with increased acceptance. NVDA (non Visual Desktop Access) is a free screen reader developing under an international project of innovative and energetic participants with support from Mozilla and Yahoo!. I use NVDA for all my web browsing and Windows work, although I probably spend more hours with nonPC devices like the Levelstar Icon for Twitter, email, news, RSS as well as bookSense and Bookport for reading and podcast listening. NVDA continues to be easy to install, responsive, gradually gaining capabilities like Flash and PDF, but occasionally choking from memory hog applications and heavy duty file transfers. Rarely do I think I’m failing from NVDA limitations but I must continually upgrade my skills and complaint about website accessibility (oops, there I go again). Go to:

The voice issue for NVDA is its default startup with a free open source synthesizer called eSpeak. The very flexible youngsters living with TTS (text-to-speech) their whole lives are fine with this responsive voice which can be carried anywhere on a memory stick and adapted for many languages. However, oldsters often suffer from Synthetic voice shock” and run away from the offensive voices. Now devices like Amazon Kindle and the iPod/iTouch gadgets use a Nuance-branded voice quality between eSpeak and even more natural voices from Neo Speech, ATT, and other vendors. Frankly, this senior citizen prefers older robotic style voices for book reading especially when managed by excellent firmware like Bookport Classic from APH. Here’s the deal: (1) give eSpeak a chance then (2) investigate better voices available at Voice and TextAloud Store at Nextup.com. Look carefully at licensing as some voices work only with specific applications. The main thing to remember is that your brain can adapt to listening via TTS with some practice and then you’ll have a world of books, web pages, newspapers, etc. plus this marvelous screen reader.

Apple Mania effects on Vision Losers

Translation:What are the pro and con arguments for switching to Apple computers and handheld devices for their built in TTS?
Good question. Screenless Switcher is a movement of visually impaired people off PCs to Macs because the latest Mac OS offers VoiceOver text-to-speech built in. Moreover, the same capabilities are available on the iPhone, iTouch, and iPad, with different specific voices. Frankly, I don’t have experience to feel comfortable with VoiceOver nor knowledge of how many apps actually use the built-in capabilities. I’m just starting to use an iTouch (iPod Touch) solely for experimentation and evaluation. So far, I haven’t got the hang of it, drawing my training from podcasts demonstrating iPhone and iTouch. Although I consider myself skilled at using TTS and synthetic speech, I have trouble accurately understanding the voice on the iTouch, necessary to comfortably blend with gesturing around a tiny screen and, gulp, onscreen keyboard. There’s a chicken-and-egg problem here as I need enough apps and content to make the iTouch compelling to gain usage fluency but need more fluency and comfort to get the apps that might hook me. In other words, I’m suffering from mild synthetic voice shock compounded by gesture shyness and iTunes overload.


My biggest reservation is the iTunes strong hold on content and apps because iTunes is a royal mess and not entirely accessible on Windows, not to mention wanting to sell things I can get for free. Instead of iTunes, I get my podcasts in the Levelstar Icon RSS client and move them freely to other devices like the Booksense. Like many others with long Internet experrience, such as RSS creator and web tech critic Dave Winer, I am uncomfortable at Apple’s controlling content and applications and our very own materials, limiting users to consumers and not fostering their own creativity. Could I produce this blog on an iPad? I don’t know. Also, Apple’s very innovative approach to design doesn’t result in much help to the web as a whole where everybody is considered competitors rather than collaborators for Apple’s market share. Great company and products, but not compelling to me. The Google OS Android marketplace is more open and will rescue many apps also developed for Apple products but doesn’t seem to be yet accessible at a basic level or in available apps. Maybe 2010 is the year to just listen and learn while these devices and software and markets develop while I continue to live comfortably on my Windows PC, Icon Mobile Manager and docking station, and book readers. Oh, yeah, I’m also interested in Gnome accessibility, but that’s a future story.

The glorious talking ATM

Terms used to reach this blog

  • talking ATM instructions
  • security features for blind in ATM


What could be more liberating than to walk up to a bank ATM and transact your business even if you cannot see the screen? Well, this is happening many locations and is an example for the next stage of independence: store checkout systems. Here’s my experience. Someone from the bank or experienced user needs to show you where and how to insert your card and ear buds plug. After that the ATM should provide instructions on voice adjustment and menu operations. You won’t be popular if you practice first time at a busy location or time of day, but after that you should be as fast as anybody fumbling around from inside a car or just walking by. Two pieces of advice: (1) pay particular attention to CANCEL so you can get away gracefully at any moment and (2) always remove ear buds before striding off with your cash. I’ve had a few problems: an out of paper or mis-feed doesn’t deliver a requested receipt, the insert card protocol changed from inline and hold to insert and remove, an unwanted offer of a credit card delayed transaction completion, and it’s hard to tell when a station is completely offline. I’ve also dropped the card, sent my cane rolling under a car, and been recorded in profanity and gestures by the surveillance camera. My biggest security concern, given the usual afternoon traffic in the ATM parking lot, is the failure to eject or catch a receipt, which I no longer request. But overall, conquering the ATM is a great step for any Vision Loser. It would also work for MP3 addicts who cannot see the screen on a sunny day.

Using WordPress</h4

Terms:

    >

  • Wordpress blogging platform accessibility >

  • wordpress widget for visual impaired

Translation: (1) Does WordPress have a widget for blog readers with vision impairments, e.g. to increase contrast or text size? (2) Does WordPress editing have adjustments for bloggers with vision impairment?


(2) Yes, ‘screen settings’ provides alternative modes of interaction, e.g. drag and drop uses a combo to indicate position in a selected navigation bar. In general, although each blog post has many panels of editing, e.g. for tags, title, text, visibility, etc. these are arranged in groups often collapsed until clicked for editing, if needed. Parts of the page are labeled with headings (yay, H2, H3,…) that enable a blog writer with a screen reader to navigate rapidly around the page. Overall, good job, WordPress!


However, (1) blog reader accessibility is a bit more problematic. My twitter community often asks for the most accessible theme but doesn’t seem to converge on an answer. Using myself as tester, I find WordPress blogs easy to navigate by headings and links using the NVDA screen reader. But I’m not reading by eyesight so cannot tell how well my own blog looks to either sighted people or ones adjusting fonts and contrasts. Any feedback would be appreciated, but so far no complaints. Frankly, I think blogs as posts separated by headings are ideal for screen reading and better than scrolling if articles are long, like mine. Sighted people don’t grok the semantics of H2 for posts, h3, etc. for subsections, etc. My pet peeve is themes that place long navigation sidebars *before* the contnent rather than to the right. When using a screen reader I need to bypass these and the situation is even worse when the page downloads as a post to my RSS clinet. So, recommendation on WordPress theme: 2 column with content preceding navigation, except for header title and About.

Books. iBooks, eBooks, Kindle, Google Book Search, DAISY, etc.

Terms

  • kindle+accessibility
  • how to snapshot page in google book
  • is kindle suitable for the visually impaired?
  • how to unlock books “from kindle” 1
  • is a kindle good for partially blind peo 1
  • access ability of the kindle

I’ll return to this broad term of readers and reading in a later post. Meantime, here’s an Nytimes Op article on life cycle and ecosystem costs of print and electronic books. My concern is that getting a book into one’s sensory system, whether by vision or audio, is only the first step in reading any material. I’m working on a checklist for choices and evaluation of qualities of reading. More later.

Searching deeper into Google using the Controversy Discovery Engine

You know how the first several results from a Google search are often institutions promoting products or summaries from top ranked websites? These are often helpful but even more useful, substantive, and controversial aspects may be pushed far down in the search list pages. There’s a way to bring these more analytic pages to the surface by easily extending the search terms with words that rarely appear in promotional articles, terms that revolve around controversy and evidence. Controversy Discovery engine assists this expanded searching. Just type in the term as you would to Google and choose from one or both lists of synonym clusters to add to the term. The magic here is nothing more than asking for more detailed and analytic language in the search results. You are free to download this page to your own desktop to avoid any additional tracking of search results through its host site and to have it available any time or if you want to modify its lexicon of synonyms.
Some examples:

  1. “print disability” + dispute
  2. “legally blind” + evidence Search
  3. “NVDA screen reader” + research Search
  4. “white cane” + opinion Search
  5. “Amazon Kindle” accessibility + controversy Search

    Feedback would be much appreciated if you find this deeper search useful.

    Adjustment themes: canes, orientation and mobility, accessibility advocacy, social media, voting, resilience, memories, …

Reading, Ranting, and Computing: 2009 Heroes and Meanies

December 31, 2009

This post sums up 2009 from the perspective of a Vision Loser immersed in assistive technology, avidly learning about accessibility techniques and trade-offs. Sighted readers should glean more about how screen and book reading tools are advancing allowing print disabled people more freedom and enjoyment, at ever lower costs. Partially sighted people can learn how I am finding and using this technology. I call out some heroes and name some stupendous products. But no amount of technology can overcome the “meanies” of slighted social services and educational bases.


First let me thank comment ors and communicators about this blog, which wanders from emotional to technical to political to memoirs. I am always touched by search terms in the blog stats that indicate others are wondering: “what is ‘legally blind’ or ‘print disabled’? how to read Google book search images? why is the white cane significant?” Medical specialists don’t explain these, the disability community has its own vocabulary and modes, and often Vision Losers cannot find another person to query. I hope this blog reflects one person’s transition in useful terminology with practical advice. Please share your experiences here or ask direct questions.

Accessibility Heroes of 2009


My heroes are people who make a difference positively in my Vision Loser life space, often using their resources very wisely then communicating freely and with passion.

The Twitter #Accessibility Constellation

Suppose you are immersed in a subject that strongly influences your daily life
and has morphed into a social cause, say public gardening, or water
conservation, or web accessibility. Imagine you could walk into a conference ballroom and overhear conversations among the subject’s professional experts: reading recommendations, standards progress, emerging contentious issues, new technologies, and professional rumors. Add a dose of spirited interchange, sprinkled across 24 hours a day, with the blessed limitation of 2 lines per utterance. Allow yourself to interject a question or opinion occasionally to test your growing knowledge and appreciate any response from your virtual mentors. For me, this has been the Twitter #accessibility experience of 2009: virtually joining a constellation of accessibility stars and superstars.


so, let me thank the Opera web evangelists, STC accessibility sig, CSUN organizers,IBM accessibility, Mozilla developers, independent web consultants, and standards group members, who line up my browser tabs with hours of worthwhile reading. Most of these communicators use blogs for irregular longer explanations like iheni ‘making the Web Worldwide’ post on ‘Adventures of silver surfers’.

Special Mentions of Useful Work


Especially I appreciate:


wow, I sure learned a lot in 2009, 140 character message at a time, adds up rapidly. Little did I know starting to appreciate Twitter in early 2009how it would influence my web life..

The Great book Reader Game, Fueled by Bookshare

Hold on to your ear buds, this is a great era of reading technology advances, also known as “Digital Talking Books”, represented in DAISY format. When I got my print disability certification and joined bookshare.org in 2006, I started using book reading software on a clunky Toshiba laptop. With no real advisors, I stumbled onto the best reader of the time bookport from APH, the American Printing House for the blind. At first, I was daunted by the array of keys arranged into
combinations that implemented amazing reading functions. Motivated by then tiring regime of audio CD library transactions and cranky players, I rapidly grew to appreciate Precious Paul on the bookport reading my bookshare DAISY downloads.


But then came the Levelstar Icon Mobile Manager in 2007 that could connect wirelessly and bypass PC to bookshare, with an entirely natural Newsstand for retrieving national papers through the NFB news line. Since I preferred the more robust device and flexible reading by bookport, I simply transferred DAISY books from Icon to Pc to bookport every few weeks.


Comes 2009 and the CSUN exhibit hall and I found the Plextalk Pocket. Definitely more streamlined with a great recorder, now I also transferred my DAISY books to its SD card. But I never really felt comfortable with the PPT menus, voice, and reading routine.


Within a few months came the booksense from GW Micro with the best available neo speech voices in a candy bar size with more comfortable navigation. All right, now I get motivated to organize my hundreds of DAISY books into categories and I have references and fiction with me anywhere. Also my latest podcasts transferred from Icon and a bunch of TXT and HTML files. By the way, I had a fantastic simple shopping experience for Booksense at I can See My PC.com.


Oh, there’s more to come. recently reported is another incarnation of the
bookport based on Plextalk Pocket
and a promised something from Kurzweil. speaking business for a moment, bookport was sadly discontinued due to manufacturer limitations. however, companies in Korea and Japan are supplying the designs and components for American company specification and distribution. the worldwide market is somewhat like the cell phone industry where circuitry and casing, fingertip embossing, and, most important, commodity synthetic voices will bypass
traditional desktop and laptop computers. We’re riding a great wave of technology to enable us to exploit services like bookshare and its impressive educational movement.


Where is the Kindle in all this? Well, as I wrote in Amazon-ASU, Kindle, what a mess”, they blew off the disability market by not making their menus and device operations then accessible, then tried to launch into the college textbook sphere, a sore point for ADA requirements to transform print into print-disabled readable formats. Add in publisher and author concerns, and a perfect storm ensued. OK, I buy through a less cluttered alternative amazon interface but, dammit, those “get your Kindle now” come-ons are disgusting.


As to the bookshare library fueling my reading rampages, I appreciate publisher contributions but especially volunteer scanned and validated books. While I find it hard to segregate teenage reading for the bookshare special ed commission, I continually grow my library from changing personal interests and
new acquisitions. Recently, I took a course on Winston Churchill in order to fill in massive gaps in my world history knowledge and found a whole sub collection of WC books for the downloading. often I hear a Diane rehm interview or reader review and have the book in seconds. while Overdrive and Audible formats are great occasionally, I’ll take DAISY books read by Paul or Kate from my pocket or pillow anytime.


So, 2009 was great for pleasures of audio reading for this print-disabled reader . And 2010 is enticing. so many books, such enthusiastic book clubs, it’s hard to believe my reading life could be so comfortable and keep me engaged and learning every day. thanks, Bookshare, especially.


However reading books is complemented by the “web magazines” of lengthy podcasts, with demos, dialogs, and product plugs. Most useful to me is AccessibleWorld.org, and its heroine founder Pat Price for mature discussions oriented to a wide Vision Loser audience.

The mixed breed Apple tree and iPod Touch


It’s too early to tell for me, but the iPod touch is, well, an eye-opener, or maybe, finger stimulator. The transfer of speech enabled interface from Mac Os to touch screen is rather elegant and yet perfectly conventional for someone used to things that talk. I’m still practicing my flicks, learning menus and screen layouts, and adjusting to voice and volume. My iPod Touch guide is a Blind Cool Tech podcast.

Frankly, I don’t know if I’ll really
use the device in my daily routine or pass it on to the grateful hands of my helper relative. For me, this is an experiment in keeping up in two ways (1) the interface and (2) the app market. Now I know better what people are raving about, at the very least. Unfortunately, I hate iTunes as a cluttered mess, reluctantly made partially accessible by apple, and not as good a podcatcher as the Levelstar icon RSs client. I despise being driven into stores, to get something in the midst of other stuff I do not want to think about, let alone buy. so, a reluctant shopper has yet to find the hook that will make me a senior “silver surfer” happy app user and podcast listener. stay tuned.


Maybe most important is that the Touch and iPhone commemorate a unification of assistive and mainstream markets. When my fingers get better enabled, I’ll be able to converse with sighted people about similarities and differences in using these mobile devices. Ha, I might even seduce a few into TTS appreciation, leading to my ideal world where everything talks fluently and informatively. I even appreciate how Talking ATM technology helps Vision Losers manage , a fascinating tale of advocacy that makes daily life more normal.

People Who keep me going


Making this short, since I do get emotional, I truly appreciate my family and friends putting up with my frustrations, crazy ideas, and needs for transportation and shopping. Daily life details with partial vision are so much harder than I could have imagined. where’s my Icon case? Oh, on the black table, not the white contrast pad. that phone number I forgot to record? any medicare notices in the mail? whisper then please forget my PIN on grocery checkout. Hold in memory 10 things to do, ask for help, then re-ask a forgetful student helper. Coordinating schedules for lifelong learning and traditional college classes… I would never make it through the day without the freedom of a brisk 2 mile cane-free walk late afternoons.


Ouch, there are meanies in this life. Great retirement areas are not truly great unless they trade off a bit of housing, view, and roadway for public transportation for economically, physically, or temporarily disadvantaged people. Nothing would be so beautiful as a bus or van coming along the connector street a block away from home, taking me the few miles to lifelong learning classes or downtown restaurants or nearby shopping. Yes, I can walk but, well, why die of a fear from a careless driver in a pedestrian-unfriendly town. now, there are volunteer services, but we are talking about civilized life here, requiring taxes and attention, too often withheld by meanies. The sweetest words are “need a ride?” but at just the right time, if only there were a $5 routine impersonal option, sigh.. However, <a href="https://asyourworldchanges.wordpress.com/2009/06/28/resilience-bouncing-back-from-vision-loss/&quot; Resilience as a quality of life for Vision Losers comes with the territory, and plenty of authors have advice and role models to reverse these thoughts about meanies.


I also appreciate the opportunities from OLLI lifelong learning at Yavapai college where I can take a variety of courses to fill in my lifelong knowledge gaps. Luckily I can also expose others to social media trends and techniques to older adults as well as my showing off neat reading gadgets and growing skills.


New retirees often go through a memoir-ish phase until realizing the hard work involved. For me, post-Sputnik educational opportunities hooked me on computing . I am fascinated by whether NOT being first helped the USA start activities that profoundly influenced our lives, like, oh, say, the Internet. Beep-beep-beep that’s the way it was.


As I gradually understand better the needs of Vision Losers, I appreciate the generational demands on caretakers, need support and training. More on this topic in 2010.

The “Meanies” who could do better

Accessible Computing Mockery (ACM) happily behind the times

Knowing better, I mistakenly rejoined a professional association,acm.org, to gain access to its digital library. I sought to complete my publication repository, back to 1970s, maybe update some loose threads in a retrospective, and learn what I could from scholarly research on accessibility, usability, and assistive technology. For $200, I found myself struggling very hard through myriad metadata details to find items and, horrors, PDFs. in a layout table of search results, with headings left to site navigation. Quickly realizing it wasn’t this hard on google or bookshare, I asked through feedback for accessibility assistance. No response, asked again, 4 times. Complaining through other professional channels, I finally got a”well, we’ll update our CMs, sometime”. Invited to consult my tax advisor about considering a lifetime ACM membership, ha, I asked for my money back, declaring NFW I’d renew. Now, that’s just plain bad service to a professional contributor asking for ADA assistance. Strictly speaking, the entire site is technically accessible but using deprecated conventions a decade old. “It’s the headings, STUPID!”, I wanted to shout but knew I’d waste words and energy.


Sadly, my later post on ‘grafting accessibility onto computer
science education’
showed a widespread ignorance of simple, effective web standards across university and computing association websites. ever wonder where so many software accessibility problems come from? As a Cs educator myself, I stand guilty excluding my last semester when I wised up , conquered denial and deception, and tried to learn to guide software engineering projects. Believe me, accessibility isn’t in the Cs curricula, textbooks, or radar screens of more than a few research groups. Moreover to read their publications, and there are many good ideas and experiments, you need to fork over $$ to ACM through personal or institutional membership. and fight that deprecated portal monument to inaccessibility. Beware, my activist archetype will guide me through another year of asking Computing educators and NSF program personnel about accessibility inclusion of distributed pedagogical tools. Professional organizations like ACM and CRA should truly lead, by example, and minimize harm by taking their noses out of the federal funding trough and looking at their own disability demographics and responsibility to the society that depends upon computing products. Please see my constructive analysis and comments in the
December 7 post honoring the (only 10 accessibility errors) National Cs ed week.

The wealthy who starve rehab and transit services


In august I ranted about health insurance denial for being a vision Loser . While my anti-protected-capitalism streak still labels these companies and their protectors as the greatest meanies I could imagine, I now have a few more thoughts. Traveling to Canada in the midst of tea bag town halls I realized the U.S.A. was losing ground with other countries in both spirit and material senses. Wrangling among political factions on enormously costly and complex systems like health care is a failing situation that allows others
who resolved these issues a half century ago to improve their worlds without our anxieties and get on with other challenges the U.S.A. cannot adequately work on. In other words, we’re unhealthy due to this wrangling in a possibly fatal or declining sense.


closer to the situation facing Vision Losers is our sparse rehab system. Marvelous treatments now allow macular degenerates to prolong their vision loss experience until we all may possibly have access to stem cell interventions and repair. But eye conditions like mine, myopic macular degeneration and glaucoma, are often just plain not reversible or controllable. vision loss, Like other sensory changes, is part of aging or injury or birth, and medicine isn’t the solution. rather, people with these conditions need rehab, training, and support more than medicine. If I hadn’t found a white cane and a little OMT (orientation and mobility training) I would likely be more damaged from falls or dispirited from being home-bound. the OMT cost, a few eye doctor visits and tests, made more difference to my life. Where does this rehab fit into the health care system? who pays? taxes? donations? volunteers? Really, we’re talking about a layer of our social services that must be maintained by taxes from all, believing that a proper role for any government is to diminish pain to unfortunate people and also enable them to reach their potential. Anybody who would deny OMT funded by a few dollars of taxes per citizen is a big, old, meanies in my very well informed opinion. come on, Americans, especially Arizonans, let’s give up a picture window in our dream homes, a trip to a Broadway play, or even a solar panel in order to support the education and salaries of the rehab layer of society. Your vision slips, you don’t want to move to a city with Lighthouse or SOAVI, where are you going to get needed training? again, this is just a matter of civilization, and a bit of wealth sharing.

Wishes for a better 2010

  1. An AccessibleX for every open service X. AccessibleTwitter shows how an web designer committed to accessibility can create a usable alternative interface to a service that chooses not to adopt standards or embrace its disabled users. So be it, big open X, but you’ll lose direct advertising revenue and loyalty, if that matters. Google WAVE is a great example.
  2. Really open book services. Google Book Search throws up unreadable page image that limits scholarly accomplishments of visually impaired people, like me. google should work a deal with Bookshare to send page text to qualified people as part of their settlement to exclusively manage intellectual property of millions of authors.
  3. A simple web-based RSS reader. RSS is the vein of gold in our web infrastructure that conducts blog posts and news updates to our attention with less web clutter and more convenience. My Levelstar Icon RSS client is perfectly simple, works for podcasts and text feeds, and collects 150 tributaries into one flow. But, Crossing the RSS divide for more web users is a challenge we need to address, including the .gov feeds.
  4. The end of stupid CAPTCHAs. These ugly buggers caught on as a symbol of human superiority to troublesome bots. “Prove you are human, decipher this image or sound track” if you also have acute enough vision or hearing. Sorry, AI lovers, but WordPress, for example, gets by with a good spam filter and email confirmations. OpenId requires one authenticated existence to prove humanity to other services. The blind communities have their own volunteer CAPTCVHA solvers, but why should a segment of society with 70% unemployment bear the costs of CAPTCHA entries to blogs and services? Think before using them, CAPTCHAs are not cool.
  5. More and better communication of academic computing professionals, especially educators, with web accessibility consultants and standards organizations. Indeed, there is a “science of accessibility” with framework of concepts, criteria (perceivable, operable, understandable, and robust), engineering principles (POSH=Plain Old Semantic HTML”), progressive enhancement design process, empirical studies, validation and design tools, all based in the current mantra of “computational thinking”. The ACM and IEEE should tear down their paywalls and expose their taxpayer-funded research results for everybody, rather than let ideas languish and researchers proceed in academic chambers. The current situation breeds out accessibility knowledge badly needed for future generations of mostly web and mobile usage.
  6. Engage designers and offer prizes for renovation of websites falling behind the times and below standards, as found in our recorded tour of stumbling around academic computing websites. True, the allure of good websites is a decade ago for many CS departments, often with control ceded to IT or New Media departments. In my experience, most students wanted to, but rarely had the chance to, participate in a design project aimed at utility, universality, and beauty. Website design is exactly that, with the added challenge of back end server and database architectures. Seriously, I ask, which is the best USA CS department website? Why? and how does it reflect its faculty, staff, and students?
  7. A pie chart manipulator to replace pictorial charts. With more and better data coming from the USG and computational engines like Wolfram Alpha, visually impaired people are stuck reading painfully through tables or using under-explained image texts. Tactile devices engage science and engineering students, but are there other options? Is there a widget that works the brain through fingers to explore and assimilate data just like looking at a pie chart? Our brains do amazingly well with TTS through ears rather than printed text through the eyes. Are we underutilizing our senses, individually and in combination?
  8. Continued progress and support for a modern technology USG, including conquering forms. We will all have improved services and information, provided gov websites apply accessibility principles and seek then use our feedback. What would really help is one good HTML form style that all websites could adapt and save citizens from stumbling around or abandoning our agency interactions.

  9. Every Vision Loser receives adequate orientation and mobility training, access to public transportation, support in daily living, and continuing opportunities in using software, networks, and web services. Not only students, job seekers, and veterans deserve services but also the aging who have so much to give back to society and so much to lose from isolation or falling behind.

Best wishes for a productive, stumble-free,, tweet-full, and fun 2010

Amazon Kindle, Arizona State, Accessibility — What a mess!

July 6, 2009

The ACB and NFB lawsuit against ASU-Amazon textbook test program is a big deal for discrimination activism and an educational opportunity on accessibility. The detailed complaint explains difficulties of blind student textbook use at ASU and how adoption of the Amazon Kindle trial program will set a bad example.


The textbook program has caught Television public interest reports on journalism student Darrell Shandrow. Comments in Chronicle.com Wired Campus report on the lawsuit have invoked understanding and support mixed with political outrage at ADA accommodations. Related issues on Reading Rights activism on publisher/author control over text-to-speech cloud the issues of accessibility of the Kindle device itself.


The purpose of this post is to inject my own opinion as well as link to some useful resources.
I speak as a former educator who struggled with textbook bulk and price; software engineer with spoken interface development experience;
and research manager with technology transfer background.
Although not a member of either ACB or NFB, I am a
visually impaired avid reader living hours a day with text-to-speech and affectionate owner of many assistive tools described in this blog.
Oh, yeah, also an Arizona resident with some insight into ASU programs and ambitions.


I try to untangle the arguments my own way. Based on my own ignorance of a few years ago, I suspect many sighted people and those in process of losing vision lack understanding of how audio reading works. I provide a recorded demo of myself working the menus of a device for book and news reading to show the comparable capabilities lacking in the Amazon Kindle.
By the way, I’ve never seen, fondled, or considered buying a Kindled.

Untangling the Kindle-ASU-textbook Arguments

  1. Text-to-speech (TTS) is the work horse, the engine, for assistive technology (AT) for visually impaired (VI) people. TTS reads content as well as providing a spoken interface for menus, forms, selections, and other user operations. Nothing novel, implemented in dozens of devices on the market, standard expected functionality to support accessibility.
  2. Amazon product designers included TTS presumably to provide a talking interface for mobile, hands-full users. TTS could read unlocked books, news, or documents downloaded to the Kindle, but only on Kindle software and rights management platforms. This established TTS as a mainstream commodity functionality, much like a spell checker as expected in any text processor.
  3. Book authors reacted that TTS represented a different presentation for which they could not control pricing or distribution. Amazon said, “ok, we’ll flip the default to give publishers control over enabling TTS”. Accessibility activists complained “hey, you just took away an essential attractive feature of the Kindle” and “You authors, don’t you want us to buy your books in a form we can read as immediately as on-screen readers”.
  4. More experience with the Kindle revealed that the TTS capability was not implemented to support the spoken interface familiar for VI people in commodity AT devices. See our downloadable demo and referenced tutorials to understand the critical role of spoken interfaces.
  5. Bummer. The Kindle that promised to become a main stream accessible reading device was a brick, a paperweight, a boat anchor or door jamb if it weighed enough, just an inert object to someone who could not read the buttons or see menus and other interactions. Useless, cutting off 250,000 books and every other kind of content Amazon could funnel into the Kindle. Well there’s always Victor Reader, Bookport, Icon, and a host of other devices we already own plus services like Bookshare, NFB Newsline, NLS reading services, Audible commercial audios, etc. Disappointed, a step forward missed.
  6. Now universities enter the picture with a partnership opportunity to test out the Kindle on textbooks for selected courses, an educational experiment for the next academic year. Rising complaints from students about textbook costs, often $500 per semester, plus chronic dissatisfaction with the packaged all-in-one book has lead to alternative formats, even abandonment, of textbooks in many subjects. Great opportunity here to re-examine educational benefits of a product and distribution system already familiar to tech-greedy students. But would the learning outcomes hold up? Amazon doesn’t say how rigorous this test program would be, but at least there’s be more Kindle-driven classroom feedback.
  7. Uh, oh. Those darned blind students can’t use the Kindle. Can universities block them from Kindle trial courses? or let them in, relying on the established accessible material support practices forced by A.D.A.? This messes up the trial because the total population of students unfortunately includes visually impaired and a range of other disabilities. Of course, there could be an economic winner here to reduce accessible material preparation costs, easily as much as the $500 Kindle when all staff and scanning prep time are included. Or even insights might be gained into how Kindle mitigates learning difficulties for some disabilities. Ouch, though conversely, it could be that reading on-screen amplifies learning difficulties students have overcome with print practices. Well, it’s a trial, an experiment, right? But, actually, this taxpayer and researcher asks, what are the parameters and the point of the trial program with several universities? Huh, just asking, can’t find any detail.
  8. So the well-lawyered NFB and ACB get together and back a long-time accessibility activist and now ASU student in a lawsuit injunction. Why get so huffy and legal? Outsiders don’t know in detail what mediation or requests have already been suggested and rebuffed but, just guessing, these organizations are probably long on experience and short on patience on accessibility issues and promises. There’s a history of Apple pushing onto universities IPods and ITunes when these devices and services weren’t accessible. Settling with the Massachusetts blind services, Apple finally got out an accessible ITunes. Amazon has a legal record on accessibility as does the LSAT.com registration website. I can well understand the reasoning that a big gorilla like Amazon won’t take time for accessibility if it can avoid doing so, for both profit and ego motives. The lawsuit simply says “Time out! Amazon, you can make the Kindle accessible just like standard practice with AT we already use.” And “ASU and other universities, don’t even think of harming VI students or taking on a tainted experiment that excludes VI students”. What’s the hurry, everybody? The textbook problem won’t be solved next year, the market will always be there, so it’s possible to have a trial that’s fair, responsible, and more informative if accessibility is counted in.
  9. Now, even local Phoenix television stations got interested in the story and, wow, what an educational moment! ASU public relations, still not recovered from their Obama honorary degree fiasco, responded with a flat “we have disability services in place. That’s enough!”. But this taxpayer thinks differently. Part of the experiment is rapid delivery of texts and other materials, perhaps challenging or disrupting disability services. And if the Kindle device itself is part of a trial, then what happens with students using alternative, perhaps even superior, technology? Trivia like different pagination in Kindle texts compared with converted texts distributed to VI students might introduce problems. Isn’t this setting up the trial for either (1) obvious bias by exclusion of VI students or (2) additional burden on VI students? Why not just wait until the device is comparable enough that harm is minimized and more is knowable in the long run about learning outcomes and economic models?
  10. But, wait, there might be a real technology barrier here. Software engineers know that the cost of repair for a missing requirement goes way up long after design, becoming deadly after deployment. Accessibility was not a requirement for the reader device although it’s a legal requirement in the university marketplace. Oops, this was a blunder. If the design of the Kindle software permits sliding in functionality like calls to the TTS engine, retrofit might not be too bad. But there’s a browser, keyboard, and lots of interactions that could get tricky. Usability is notably difficult to do well without experimentation and iteration. So, this is just one more case study relevant to the many software engineering texts in the Amazon market.
  11. Finally, as others have commented, regarding the Chronicle.com forum, railing against A.D.A. as an intrusion on public rights, a sign of backwardness for disabled individuals, and general disregard of human rights is, well, sickening. I wish those detractors a broken leg during a health insurance lapse with a long flight of stairs to the rest room. That’s life, bozos, and we’ll all be disabled in the long run.

What is the listening experience? Hear me show you!

I use the Levelstar Icon to download books from Bookshare.org. My library is currently about 1000 books, complemented by daily doses of news feeds and newspapers. I’ve turned this situation into a demo:

download the 15 minute AYWC-reading-demo.mp3 from http://apodder.org/stumbles/
You’ll hear me narrating book downloads and reading. The demo illustrates both (1) TTS reading books and news and (2) working around menus and lists of books do perform operations commonly shown ona screen. This latter capability is the crux of the Kindle accessibility disagreement.


For more information on this device and interface, the Levelstar.com audio tutorials illustrate the standard practice of supplanting screens with voice-enabled menus. For the record, the operating environment is Linux and the designers of the Icon and its partner product APH BraillePlus are blind. Personally, I think the mainstream product capabilities have a lot to learn and gain from the AT industry it has so far excluded. Perhaps, following the Curb Cuts principle even better, universal designs will emerge from this mess.

Hear Me Stumble Around White House, Recovery, and Data GOV web sites

May 31, 2009

This post takes a tour by screen reader of the new U.S. government web sites
whitehouse.gov,
recovery.gov, and
data.gov.
Using recorded sessions, I analyze my techniques and problems. Sighted readers will experience some of the confusions and frustrations of a visually impaired person trying to learn the interaction and structure patterns of these website’s. Visually impaired users may glean some ways to avoid pitfalls and determine the value of these government information resources for their purposes. I complain about absence of headings, careless links, and tricky interactions beyond my capabilities although I appreciate the effort to provide high quality government information.

Why is “Hear Me Stumble” useful?

I’ve tried this practice several times in the past year with a mixture of consternation and learning. Basically I record myself using a website to the best of my abilities, talking to myself as I go. The results are useful in several ways:

  1. A historical snapshot of the website under study, the tools I’m using, and my skills is now recorded for posterity.
  2. I use the recordings to diagnose my own deficiencies and document changes in my own web practice.
  3. With increasing confidence in my knowledge of the field of accessibility, I try to explain deficiencies in terms that website designers can understand to improve their designs and implementations Ditto, tool developers such as screen readers and browsers.
  4. The recordings also describe ways of testing that could and should be used before website release to improve the experience for visually impaired users and to meet statutory requirements.

    .

Yes, if you listen to these recordings, you’ll hear a good bit of frustration with my own mistakes as well as some depressing practice, indeed perhaps malpractice, on the part of website designers. In the case of the .gov websites, we’re watching the expanded use of the Internet for citizen interaction so appropriate corrections of certain problems could have a highly amplified effect across the population of U.S. citizens. Fortuitously, if we apply the ‘curb cuts’ principle, fixing certain problems will likely make the websites better for everybody, disabled or not, and we’re all disabled in the long run. Furthermore, the current websites are exhibiting trends using social media beyond the knowledge of many of my generation, the baby boomers and beyond. In effect, many of the populace who need data available from U.S. government websites are those least likely to be able to benefit.


A big caveat here is that these websites are “young” and experimental, sort of like new drivers proud of their licenses and wheels but not fully understanding the rules of the road. Anxious to get their acts in gear, these drivers are sadly vulnerable to mistakes that might make unfortunate hood ornaments out of senior citizens, ignoring limits of other vehicles and pedestrians using the same roads in different ways. Continuous partial attention dictates websites that change every few seconds, seeking to hook users into feeds and social web practices. This is the most important time in the evolution of these websites to instill good sense, modesty, empathy, etc. as well as correcting patterns known to be detrimental, if not outright illegal. Ok, end of lectures I’ve given many times to teenagers, especially as I become more wary as a non-driver in a cell phone and vehicular world.

An audio tour of WhiteHouse.gov

First, go to http://apodder.org/stumbles to retrieve the two recordings in MP3 format, a total of around 60 minutes.

On May 29, 2009, President Obama and government officials released a cyber security policy statement that I sought to find on the website. The main events described in the recordings were:

  1. I took a “headings tour” of the website, trying to build a mental outline of sections and subsections wherever I heard like “Briefing Room heading 2”. This heading outline seems improved over my January explorations, but perhaps I’m only more familiar. Here is how whitehouse.gov looks to the WebAim WAVE analyzer. Notes: this link will show the current version of the web page not what I say on May 29. Also this is the established accessibility tool, not the newly announced Google W A V E.
  2. I was thrown off by the slide show at the top of the page. Once I hit the cybersecurity story, the next time I traverse this section the story was about the Supreme Court nominee. Earlier, I had stumbled over the 1-2-3-4 series of boxes but not connected them with the slide show. This time, a fairly good eyesight day, I could see the images were changing.
  3. So, listening to the recording, I ask myself, why I didn’t use the search box I found at level 2. Well, some introspection revealed I have been tricked too many times by website searches that bury what I really want in favor of getting me to products or just plain showing irrelevant material. I did try the search for “cybersecurity” the next day and indeed find the relevant references, but cannot determine whether the search would have yielded good results immediately after the announcement. I also found some silly references in the additional results about some conversations with the press secretary. Next time I will try the search, correcting my behavior.
  4. Several times I ran across uninformative links like “Read this post” and “Learn more”. Since I often traverse a page by link, reading one of these links is annoying. I must read backwards through the text to find the subject of the link, muttering to myself “learn more about —- what?”. This is symptomatic of a website design that hasn’t been tested with a screen reader by a member of the web site team. Ok, maybe these web designers like to hear “learn more” repeated six times in a row, but, come on, why not rewrite the text to attach the link to something meaningful and distinctive.

In summary, visually impaired users must come to terms with a slideshow that regularly changes the content of the page without any evident alert (that I could detect). The heading structure helps traverse the page but isn’t entirely intuitive. Link texts are annoyingly un informative and should be changed if the white house web designers want better usability. This web user will give the search box a try earlier next time, recognizing the inevitable need to sort through results but hoping for the most important and relevant content to be highlighted.

An audio tour of recovery.gov and data.gov


Sorry, I just have to rant here. Neither page has significant headings. So, how am I supposed to know what’s on the page without reading line by line? Find my way to the action parts of the page? Ever regain respect for an agency that doesn’t know the mantra — It’s the headings, stupid!!!”. Is this HTML malpractice?

Whoops, I’m mixing metaphors. Is this reckless driving? driving without a license? Certainly, there’s no certification of 508 or other stamp of approval, just wishful reassurance that “we’re trying on accessibility, really” and “we’re a new website, don’t expect too much”. But, hey, this citizen says, why not pay attention to the dozens of websites that and even you tube videos that advocate headings. What about running your pages through validator’s and getting clean reports from nationally recognized accessibility gurus, like WebAim WAVE report on recovery.gov and WebAim WAVE report on data.gov accessibility.

Comments on recovery.gov


I did not have a specific task here, so just wandered around.

  1. The text size adjustment option bemuses me. My browser does that for me. Reading the increase or decrease text size labels are tedious if the page reads from the top. More problematic, is that the text size graphics and buttons are off the displayed section of the page in my browser in some circumstances. In other words, someone who needs them might well not see them off to the far right.
  2. Those pie charts and graphs in the slide show look interesting but they go too fast for me to zoom or magnify. Sigh. This website, indeed the whole U.S. government if its going to work this way, needs a chart explainer or some gentler way of providing data. The timeline is so cool, too bad I cannot use it. I can see it scroll by but how do I read it?
  3. A popup tries to notify exit from recovery.gov. In my browser setup, I have no speech notice, just a box hanging on the screen with a Close button if I can find it. In the recording this threw me off. Why is such a notice needed, anyway?
  4. PDF documents may be standard with a free reader, but they are not pleasant for visually impaired users. I personally almost always crumble a PDF into its TXT form if it’s worth reading for transport to a mobile reader. Actually, I did not encounter any PDF format files to download and try but I’m sure they are there somewhere.
  5. Note: I just discovered more “Learn more” links on the News page. See above.

Comments on data.gov


This page is mainly a large search form. Now, I’m a veteran web and data searcher, but this one got me.

  1. The text is flat without headings. A heading for each part of the complex form would make the difference between usability and frustration. Turn those section titles into headings, please, please.
  2. Components of the form appear not to be labeled properly, if at all. Nothing new here, just good practice for a decade or so, and really important for a person with a screen reader to know what a form field is doing there.
  3. I got hung up in an unfamiliar, and perhaps nonstandard, kind of form. A list of agencies with check boxes is encompassed in a scroll window. This wasn’t apparent to my screen reader so I heard a lot of naked “check box” phrases unless I used line up and down. Since I didn’t know what I was in, I could not find the search button. Looking again the next day, I found the button, decoded that I needed to get out of edit into browse mode to finish the search. I declare this just plain tricky. The technical problem is many agencies that could be represented in a list except that multiple selection from a list is also hard., although standard.
  4. Ok, so if I did get a search performed, how usable are the search results? I did not find an easy way to jump to the search results, nor to navigate through them.

Uh, oh, this is an unhappy camper! How do other technologists feel?


Yep, I really don’t feel very comfortable or welcome at these web sites, despite my tax dollars at work. Granted the websites are juvenile in stages of development and that much work has gone into creating the back ends to deliver the data to the web pages. It’s really exciting that citizens may become data analysts, exploring trends and comparing communities, in the spirit of Jon Udell’s blog on ‘strategies for Internet Citizens’. It is also admirable that so many semi-commercial and open source software products are being tried, albeit without a strong accessibility requirement.


But still, so many sensible, well known rules seem to have been broken that it’s hard for me to believe that accessibility is high enough priority I can feel better about future improvements. Consistently using headings is so simple, it’s sad to see the trade-off of a standard accessibility practice with the greater glitz of scripted slide shows which further mess up accessibility.


I’m just plain disappointed in the Obama administration’s approach to web design.
And I’m not alone, e.g.
Webaxe podcast analyzing recovery.gov and
Jim Thatcher’s analysis of whitehouse.gov,

. There are people around the country making a living from building accessible websites. There are training programs, such as John Slatan Access U and WebAim Training. Why isn’t this expertise being used in the premiere U.S. websites?


Does feedback matter and how is it solicited and used? Will these websites improve?

The ‘Talking ATM’ Is My Invisible Dream Machine.

April 30, 2009

A twitter message alerted me to a milestone I surely didn’t care about a decade ago, but really appreciate now. This post explains how easy it is to use a Talking ATM. People with vision impairment might want to try out this hard-won disability service if not already users. Sighted people can gain insight and direct experience with the convenience of talking interfaces. But, hey, why shouldn’t every device talk like this?

The Milestone: 10 years of the Talking ATM

The history is well told in commemorative articles published in 2003. References below.
Pressure from blind individuals and advocacy organizations circa 2000, with the help of structured negotiators (lawyers), led banks to design and roll out Automated Teller Machines equipped with speech. Recorded audio wav files were replaced by synthetic voices that read instructions and lead the customer through a menu of transactions.

first, I’ll relate my experience and then extrapolate on broader technology and social issues.

My Talking ATM Story


As my vision slid away in 2006, I could no longer translate the wobbly lines and button labels on my ATM screen to comfortably perform routine cash withdrawals. Indeed, on one fateful Sunday afternoon I inserted my card, then noticed an unfamiliar pattern on the screen. Calling in my teenage driver, we noticed several handwritten notes indicating lost cards in the past hour. I had just enough cash in hand to make it through a Monday trip out of town, and immediately called the bank upon return Tuesday. A series of frustrating interactions ensued, like my ATM card could only be replaced by my coming in to enter a new PIN. But how was I to get to the office without a driver or cab fare when I was out of cash?


This seemed like a good time to familiarize myself with audio ATM functions, to lessen risk of having another card gobbled by a temporarily malfunctioning station. With lingering bad feelings about the branch of the Sunday fiasco, I recalled better experience at a different office after my six month saga on reversal of mortgage over-payment. Lesson learned—never put an extra 0 in a $ box and always listen or look carefully at verification totals.


I strolled into the quiet office and asked customer service to explain the audio teller operations. The pleasant service person whipped out a big headset and we headed out to the ATM station. Oddly, most stations are located in office alcoves or external walls. This one was outside the drive-by window to be shared by pedestrian and automotive customers.
ok, waiting for traffic to clear, we went through a good intro. I wasn’t as familiar with audio interfaces at that point in my Vision Loser life but I eventually worked up courage in the next few weeks to tackle the ATM myself with my own ear buds.


Well, 3 years later, I’m a pro and can get my fast cash in under a minute, unless my ear buds get tangled or I drop my cane. First problem is figuring out how to get in line, like standing behind a truck’s exhaust or walking out before a monster SUV. Usually I hang back, looking into the often dry bed of Granite Creek until the line is empty. Next step is to stand my white cane in a corner of the ATM column, feel around for the audio opening hidden in a ridged region, wait for the voice to indicate the station is live, shove in my card, and ready to roll. The voice, probably Eloquence, usually drones into a “Please listen carefully as the instructions have changed…”. Shut up, this will only take a minute and I don’t need to change volume or speed. Enter, type PIN, retype PIN if commonly hit a wrong key, and on to Main Menu (thinking of ACB Radio’s Technology jingle). 6 button down to Fast Cash, on by 20,…100,…, confirm and click, chug comes cash, receipt, and release of card. Gather up receipt, card, cane, and — important — remove ear buds, and I’m on my way.


Occasionally things go wrong. Recently, my receipt didn’t appear and customer service rep and I did a balance request and out spat two receipts, both mine. Kind of nerve wracking as somebody else could have intervened and learned of my great wealth. The customer service rep vowed to call in maintenance on the ATM, but I bet a few more receipts got wadded up that afternoon. Electro-mechanical failures often foil sophisticated software.


Another time, I finished my Fast Cash and waited for card release only to be given a “have we got a good deal for you” long-winded offer of a credit card. I wasn’t sure how to cancel out and still get my ATM card back. since I lecture family on the evils of the credit card, I was fuming at a double punishment. Complaining to the customer service rep inside, I learned sighted people were also not thrilled at this extra imposed step.


Now, to reveal the identity of the ATM, it’s Chase Bank, formerly Bank One, on Gurley Street near the historic Whisky Row of downtown Prescott AZ.
Although I haven’t performed any complex ATM interactions, it’s fair to say I’m a satisfied user and would not hesitate to recommend this to anyone with good hearing unafraid to perform transactions with engines and radios and cell conversations roaring all around. An indoor ATM would be a good step someday but, hey, this is a conservative town, not particularly pedestrian friendly. Mainly I appreciate that I can get my cash as part of a routine just like other people and I don’t even use up extra gasoline waiting in line.

Broader Issues of Talking Transactions

Does the ATM voice induce Synthetic Voice Shock?

I coined the term in Synthetic Voice Shock Reverberates Across the Divides to explain responses I heard about voices offered in assistive technologies to overcome vision loss. Personally, I hated Eloquence when I first heard it demonstrated but I rapidly grew to love my Precise Paul and friends as I realized that (1) the voices really were understandable and (2) I didn’t have any choice if I wanted to keep reading. I now wonder how people like me, slowly losing vision while off the rehab grid, learn about Talking ATM and related services. It hurts to think people give up that one step of independence from not knowing whom to ask or even if such services exist. And supposing someone does step up to an ATM ready to listen, are they tuned in to hearing synthetic speech sufficiently to make an informed choice whether the Talking Teller is an appropriate service for them? Did the Disability Rights movement fight through a decade only to have a generation of drop-outs from oldsters with difficulty adjusting to vision loss, a panoply of technology, and no-longer-young nerves?

Are Audio E-voting and Talking ATM’s Close Cousins?

I have described my experiences in 2008 voting without viewing. The voting device is a keypad like offered by the ATM I use while the voice is a combination of human narrated candidate and race announcements interspersed with synthetic speech instructions and navigation. I found this mode of voting satisfying, compared with having someone read the ballot to and mark for me. However, even my well-attuned ears and fingers seemed to get in trouble with speech speedup and slowdown, which I blame on poor interaction design. Note that many ATM and voting systems have origins in the NCR and Die bold product lines so usability and accessibility research lessons should carry over.

Why aren’t all check-out services as easy as banking?


I buy something at a store and then have a hassle at check-out finding a box on a screen or buttons I cannot see for typing in a debit card PIN. I’ve never understood why I can give a credit card number over a phone without signing but must sign if I swipe it on checkout. And giving a PIN to a family member or stranger isn’t good practice. Sometimes check-out can get really nasty as when a checker wouldn’t let me through because my debit card swiper was only age 20 – it’s my debit card, my groceries, my wine, and I’ll show you a social security age ID card. Geez, now we’re nervous every time we check out a Safeway since Aunt Susan has a short fuse after a tiring shopping session. If only the Point of sale thing talked and had tactile forms of PIN entry. I ask Safeway when accessible check-out will be possible and let them know the store has a visually impaired regular shopper.

Is audio interaction a literacy issue?


We are actually on track to a world where everything talks: microwave ovens, cards, color tellers, security systems, thermostats, etc. Text to speech is a commodity additional feature to onboard processors in digital devices. Indeed, we can hope this feature slips out of the aura of assistive technology into the main stream to enlarge the range of products and capabilities available to everybody. Why shouldn’t manuals be built in to the device, especially since the device is soon after purchase separated forever from its printed material? Why shouldn’t diagnostics be integrated with speech rather than provided on bitty screens hard to read for everybody? How about making screens the add-on features with audio as the main output channel?


Let’s generalize here and suggest the need for a simple training module to help people with recent vision loss get accustomed to working keypads accompanied by synthetic speech. Who could offer such training? I asked around at the CSUN exhibits and haven’t yet found an answer. There are multiple stages here, like producing a book and then distributing to end users via libraries or rehab services. My experience is that social services are hard enough to find and often more available to people who have already suspended independent activities.


The outreach problem is real. Finally, I’d like to express my appreciation to the activists, educators, and lawyers who convinced banking organizations and continue to work on retailers to make my “money moments” conventional and un stressful. The “talking ATM” shows what is possible not only for business but also for the broader opportunities sketched out above. Let all devices talk, I wish.

My Accessibility Check: Images and their Surrogates

February 28, 2009


This post is part of a series on my experiences with web accessibility. Each post condenses what I’ve learned from before and after as a real-life Vision Loser continuing 30 years of Internet use and as a new student of accessibility theory and practice. Sighted readers will learn a bit more about how a low vision persons uses the web and other Vision Losers may sense some of the rationale behind the annotation of graphics.

Why are ALT tags Rule #1 of web accessibility


Ok, so web pages are inherently visually motivated to exploit the power of browsers and graphic images to convey information to users. But does that mean that images can be used freely, for either decorative or information roles, without the slightest indication of their purpose on a page? Wouldn’t that be cruel to people without vision? Of course! And with increase in use of mobile devices with smaller screens, images may also be problematic for sighted people. And browsing without images showing remains common where bandwidth is limited by availability or cost. Hence, providing surrogates for images acquired the primary position in accessibility rule making.


Web standards make it implicit that web content should be perceivable necessitating alternative textual descriptions of graphics. That implementation of this rule is dead simple, to write a description as an accompaniment, denoted by the HTML identifier ALT.

Are ALT tags simple and easy to use?


Well, yes, it’s easy to add such tags. Creating web pages the power user way, with a Notepad, one adds ALT=”the description” to accompany the location , denoted by SRC, of the image. No big deal, but what would the description say? the color of the image? ithe who or where? the artful ambience? The trick here is that the ALT description should give exactly the information needed to place the image usefully in the context of the page, no more, and no less. Ouch, that requires thinking, like why have the image in the first place and what’s its role in the narrative of the page, in addition to attracting eyes and stimulating visual cortexes?


And, wouldn’t you know it, there are more messy questions as described in Web Accessibility Gone Wild from webaim.org. some images are purely decorative and some are used for layout of the page, neither of which require a real ALT description, which would only get in the way of screen readers. And there are charts and graphs where the data displayed is integral to the point of the web page. And some images just take a lot of words to describe. Furthermore, images are often associated with links where the descriptions overlap. Happily, the above article provides good commen sense practices for these situations.

Examples of Accessibility Issues for ALT and images


Images without ALT tags are often cited as “obstacles for the unsighted”, but this Vision Loser has only one experience like this. As described in previous post on “pie charts and literacy” inability to read a pie chart may have doomed my retirement funds during an analysis by my ‘Wealth Manager’. Not really, we’re all doomed, but inability to read the pie chart of asset allocations was a real bummer for me. The problem here is not so much that the pie slice relative sizes and labels were unavailable in a PDF document, but that I could not get my hands into the original data. Pie charts are not so much images as representations of data that stimulate questions about relationships within that data. I am still looking for the pie chart I can manipulate to get those relationships out of the data imprisoned in documents.


Generally, it does help to have image descriptions like ““bicyclists using curb cut in complex intersection” to force my brain into thinking about physical locations and moving objects. But rarely do I find the absence of a good description as a barrier to understanding the content of a page. With low vision myself, I don’t have much practice using images and ALT text, requiring a sighted helper to assure images are what they say.


On the other hand, now that I’m an accessibility advocate, it is annoying to find violations of Rule #1 because this may show a rather serious ignorance of or callousness toward accessibility. I recently found this in a left unnamed output of an NSF project on Broadening Participation in Computing. An excellent project to entice student interest in computing through a journalist pathway produced a newsletter with articles illustrated by images that read out to me as “497” and “2934”. All I could think of was a missed opportunity to raise the awareness of student authors about accessibility issues, like “how would your great-grandpa’s bad eyes read this page?” Our tax dollars should be properly used only when results are fully accessible. But don’t get me started on university and professional organization web sites!

What next for ALT?


Of course, there’s more to graphic media with Flash and animation. But the message of ALT seems to be:

  1. Leave off ALT tags if you want to put up a clear “No blind need apply” sign to your visiting potential clients and students.
  2. Put in the time thinking and checking out your web pages for image usefulness. Turn off images in your browser and see what’s missed. Do images still matter? Are they well supplemented by ALT descriptions?
  3. Decorative images may be vestigial ways of thinking about getting column 2 of text to start at position 43 when that’s going to interfere with text sizing requirements or be bungled in one or another browser. Or, even worse, really stupid cases are when a screen reader reads out “spacer, spacer” between words, indicating you didn’t know how to or care to test with a screen reader.
