Web toolkits accessibility study

Access to increasing number of web applications is very good news especially for disabled people. These applications become richer and offer wide variety of services used in everyday's life (document creation, instant messaging, data storage, email communication, social networking, etc.). The problem is that at the same time these rich internet applications (RIA) become less accessible. There is a Web Accessibility Initiative (WAI) 2 related to W3C 1 which is trying to cope with this problem. In particular the Accessible Rich Internet Application suite of W3C (WAI-ARIA) 3 is describing how to improve the accessibility of dynamic web content and advanced user interface controls in rich internet applications.
