Abstract

The W3C Accessible Rich Internet Application (ARIA) 1.2 specification has many new features including, harmonization of roles with HTML elements, new accessible naming and description techniques, and the Accessible Object Model (AOM) that allows a new way for scripting to set and get values for ARIA roles, properties and states. The ARIA Authoring Practices have also been updated to improve guidance in using ARIA, including combo boxes, date pickers and image carousels. Examples have been improved to demonstrate best practices for focus styling and support for OS high contrast modes. The session will also provide information on the activities of the ARIA AT working group which is testing ARIA implementation in screen reader technology to help developers better understand how ARIA effects the actual screen reader user experience and assistive technology companies a clearer picture of how they use ARIA information. Feedback and questions will be encouraged throughout the session.
