document: Web 2.0 : blind to an accessible new world With the advent of Web 2.0 technologies , websites have evolved from static pages to dynamic , interactive Web-based applications with the ability to replicate common desktop functionality . However , for blind and visually impaired individuals who rely upon screen readers , Web 2.0 applications force them to adapt to an inaccessible use model . Many technologies , including WAI-ARIA , AJAX , and improved screen reader support , are rapidly evolving to improve this situation . However , simply combining them does not solve the problems of screen reader users . The main contributions of this paper are two models of interaction for screen reader users , for both traditional websites and Web 2.0 applications . Further contributions are a discussion of accessibility difficulties screen reader users encounter when interacting with Web 2.0 applications , a user workflow design model for improving Web 2.0 accessibility , and a set of design requirements for developers to ease the user 's burden and increase accessibility . These models , accessibility difficulties , and design implications are based directly on responses and lessons learned from usability research focusing on Web 2.0 usage and screen reader users . Without the conscious effort of Web engineers and designers , most blind and visually impaired users will shy away from using new Web 2.0 technology in favor of desktop based applications .
