Abstract:

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.
