Review: Universal Design for Web Applications
Universal Design for Web Applications summarises a unified approach for designing web content so that it works better for people with disabilities and users of mobile devices. The authors identify an “overlap in needs and constraints between mobile and accessibility design”. They propose “universal design” as an approach which deals with both to provide “the greatest benefit to the greatest number of people possible”.
The pairing of mobile design with accessible design is a neat way of improving the marketability of design techniques which help people with disabilities. There’s some nice points made about the similarities between the difficulties of web-browsing on an iPhone and the problems which people with fine-motor disabilities or less-than perfect-vision can have when browsing on a PC or Mac. The authors go so far as to say that: “It could be that the current crop of mobile devices is the best thing to happen to people with disabilities for a long time. When else have millions of people stood in line with $199 or €129 or £99 in hand to purchase a functional disability?”
With an admirable brevity, the book neatly summarises the basic techniques required to meet level A compliance with the Web Content Accessibility Guidelines 2.0. There are chapters advising on metadata, separating design from structure with CSS, proper use of tables, video and audio, scripting accessible menus, accessible Ajax and Rich Internet Applications. The Ajax section includes an introduction to the basics of the W3C/WAI Accessible Rich Internet Applications (ARIA) specification. The final parts of the book include plenty of links to useful resources and a 20-point checklist of questions to ask about your site which could be of real practical benefit.
The authors avoid being too doctrinaire – for example, the use of layout tables in email design is pragmatically accepted, as email clients currently make it impossible to get predictable results out of CSS.
The book is a good little introduction to accessible design and newcomers to the field should get a lot out of it. Even readers who already know a lot about accessibility may find the odd tip which is useful to them, especially if they want to sell accessible design to clients via examples of its benefits to users of mobile devices.
