Vis-A-Wis: Improving Visual Accessibility through Automatic Web Content Adaptation

The accessibility of Web content is gaining all increasing interest and several research activities deal with standards and methodologies for enforcing Web sites accessibility and usability. In spite of all these efforts most of the actual Web sites are still not accessible at all. The reason of that is twofold: from oil side, most of Web site developers are unaware of the actual standards and methodologies for accessibility oil the other side, such standards are still too broad to address in in effective way all the accessibility issues. This paper attacks the Web accessibility problem following two different paths: (1) it focuses oil a subset of the accessibility issues, i.e., problems associated with hypo-sight and color-blindness, and (2) it provides means for automatically adapting, i.e., transcoding any existing Web page, increasing its accessibility with respect to the aforementioned disabilities.
