WAI Technical Activity Statement

The Web Accessibility Initiative (WAI) Technical Activity addresses barriers to Web accessibility on several levels. First, it seeks to ensure that the full range of core technologies of the Web, from HTML to the Semantic Web, is accessible. Barriers exist when these technologies lack features needed by users with visual, auditory, physical, cognitive or neurological disabilities; or when the accessibility potential in the technology is not implemented in Web content or applications. The WAI Technical Activity coordinates closely with the WAI International Program Office, which focuses on WAI education and outreach, web accessibility community discussion, and accessibility standards coordination. 

The WAI Technical Activity reviews accessibility support across all W3C specifications through the Accessible Platform Architectures (APA) Working Group, and develops the WAI-ARIA suite of resources for making Rich Internet Applications accessible through the work of the Accessible Rich Internet Applications Working Group (ARIA WG). The WAI Technical Activity has promoted implementation of accessibility improvements in Web technologies through development of a set of three WAI guidelines: Web Content Accessibility Guidelines (WCAG), User Agent Accessibility Guidelines (UAAG), and Authoring Tool Accessibility Guidelines (ATAG). These guidelines describe features needed to achieve different levels of accessibility, and include reference checklists and implementation techniques. Future guidelines work may be through the development of combined guidelines.
