Abstract:

It’s taken awhile, but webmasters are starting to get the hang of designing Web sites that work for most users. But don’t rest yet: webmasters will soon need to add a completely new set of Web design skills. Increasingly, Web sites will have to accommodate disabled users. Disabled users? That’s right. Even people with no sight at all can “hear” the Web, through special browsers that read out the code on Web pages. New US regulations require that all Federal sites (and the sites of Federal contractors) work in this format. Other countries are adopting similar rules, and non-government sites are increasingly coming under pressure from users to offer options for the disabled.
