ARIA

• Accessible Rich Internet Applications

• Specification developed by the PFWG of the W3C’s WAI. Huh?

• Currently published as a Last Call Working Draft

ARIA enhances accessibility of...

• ... dynamic content and AJAX

• ... scripted widgets and interactive controls

• ... keyboard interactions within a web page
