- keyboard access just like their GUI counterparts
- contextual information in line with their GUI counterparts. (Number of tabs in notebook announced. Tree depth of a focused tree element, etc.)
- Role and state information announced as you would find in a GUI
We showed this to technical leads at Yahoo and AOL and the opportunity for creating accessible, Rich Internet Applications and delivering desktop solutions on par with a rich desktop applicaions was apparent.
Completion of this project will accelerate the standards effort. As we speak a cross-cutting, self describing role taxonomy and accessibility property specficationa are getting close to working draft based on proven implementations. Industry involvement to the standards effort is now growing with the addition of Adobe. The work being developed is cross-cutting in that it has applicability to:
In the current Deer Park Alpha of Firefox, XUL makes use of the same accessibility extensions for XHTML to enable some of the custom GUI widgets found in the chrome.
Another side-benefit of this work is the creation of a new role called "presentation." The use of the presentation role tells the browser that there should be no accessibility API support for a particular document element. This can be applied to table elements to indicate that the content is only presentational and for assistive technologies not to process the table elements as a table. This eliminates the need for authors to use a special style sheet to reproduce table formatting. DHTML often uses tables to produce the visible formatting needed for rich GUI-like elements. Indicating to the user agent and assistive technology that an element is only presentational removes the burden of guessing when to treat markup as presentational vs markup containing significant semantics which might impact the user experience.[Read More]
