The accessibility community is understandably concerned about the accessibility of client-side scripting, in particular using Asynchronous JavaScript and XML (Ajax) to produce Rich Internet Applications. Steve Faulkner of Vision Australia and founder member of the Web Accessibility Tools Consortium (WAT-C) and myself on behalf of The Paciello Group (TPG) have collaborated in an effort to come up with techniques to make Ajax and other client-side scripting techniques accessible to assistive technology. The Web Accessibility Initiative's Protocols and Formats working group directly address the issue of making rich Internet applications accessible, and we borrow some of their concepts to investigate methods of ensuring that Ajax applications work with leading assistive technology products. The bad news is that it isn't possible to make Ajax work in every known assistive technology, in the same way that it isn't possible to get Ajax to work with older browsers, but we explain the fundamental issues; how to inform users of assistive technology that a change has taken place, and how they can interact with the content. To illustrate our findings, we summarise the behaviour of popular screen readers.

We've all heard a great deal of buzz about AJAX in the last few months, and with this talk has come a legion of articles, tips, presentations and practical APIs designed to explore the possibilities and try to arrive at best-practice techniques. But, for all of the excitement and hype, still very little has been said on the subject of AJAX and accessibility.
