Honoree for 2010 Ada Lovelace day = Accessibility Advocate and Educator Wendy Chisholm

March 24, 2010

finding ada is a movement in the name of 19th century programming theorist Ada Lovelace to acclaim the accomplishments of women in computing. Wendy Chisholm is a computer scientists well recognized in her field of accessibility and web design. I’d like to use this post to not only express my appreciation for her work but also to call attention to the accessibility field as a worthy versatile career path.

Chisholm’s co-authored book Universal design for web applications blends technical experience from w3c standards, snippets of programming patterns, and a deep respect for human differences. This book explains the rationale for many standards recommendations such as (my favorites) structure and semantics in headings. The now established design process of progressive enhancement is explained with strong admonitions to separate content from presentation and how to do that systematically. Many tools and checklists enable quality control over both process and product. In other words, this book is parallel to software engineering texts teaching essential knowledge and skills for professional web designers, as well as those that produce technical writings and organizational profiles in web format.

Web Accessibility for Everyone Podcast provides a profound insight into why accessibility matters so much for addressing individual differences, some designated by society as disabilities. Indeed, Wendy take the issue to the level of world peace. An example is the difficulty, using a screen reader, of finding routes in a public transit time table, typical in PDF or web pages. Indeed, the whole area of reading visually represented data is helpfully addressed in the book and a motivator for Chisholm’s computing interests. Wow, this podcasts would be a great entry point for computer science students and professionals — play it at your next brown bag lunch or design meeting.

Personally, I learned much from the book to codify my study of accessibility, as both a screen reader user and a programmer myself. I cringed often at the awful web gimmicks I used, such as layout tables and, horrors, blink. Living through and using the first generations of HTML has instilled many bad habits and , sorry, blinded us to bad practices. but, now, there’s no excuse for not gradually removing these warts and thoughtlessness that perpetuate barriers in a world where daily life and employment depend on rapid, accurate, and complete access to information from web sites. I’ve ranted here in prior posts about the decade old and now harmful qualities of computing websites such as ACM, CRA, and many Cs departments. Recently was proudly announced with good content from Turing award winners and women’s contributions to computing. but one quick pass with my screen readers showed lack of real structure and proper use of semantics as well as an egregious absence of labeled form elements. A compliance analyzer, like a static checker, confirmed these and more errors. what’s missing here? Mainly an accessibility statement identifying practices from web standards and a regimen of testing like I did in seconds. Hello, ACM, buy yourself this book and work with staff to get yourself up to snuff.

so, thanks Wendy, for providing such great educational content in an inspiring social context that rules the daily life of vision Losers like me.
