The document discusses evaluating web accessibility for specific mobile devices. It proposes extending existing mobile accessibility guidelines to account for varying device capabilities. The approach retrieves a web page's content and the device's profile to dynamically generate tests. These tests are used to evaluate the page and produce a tailored accessibility report for that device. A case study found the approach reduced false positives and negatives compared to generic tests.

3. Mobile Web vs Web Accessibility International Cross-Disciplinary Conference on Web Accessibility, W4A 2008 Guidelines Architecture Case Study Conclusions Introduction Mobile Web Web accessibility Small display size causes disorientation on the user Lack of context disorientates visually impaired users Lack of pointing device forces users to use keyboards. Navigation is slowed down Screen reader users suffer information overload : navigation bars and menus. Typing is a tedious task due to low text input rate Users with motor disabilities face analogous problems Due to low bandwidth images tend to not to be loaded Not providing alternatives for visual content raises accessibility barriers Lack of colour support may cause information loss Information conveyed with colour causes problems to colour-blind users Lack of support causes information loss Assistive technologies tend to have problems with newer technologies
