ViCRAM: visual complexity rankings and accessibility metrics

The World Wide Web (Web) has become the means of distribution and use of information by individuals around the world. However, access to this information by visually impaired people is limited due to the Web's visual complexity. ViCRAM is a project that will relate user's implicit understanding of Web page visual complexity with its layout. Eye tracking methods and knowledge acquisition techniques will be used to elicit sighted people's visual perception. During this project we will also determine whether pages that sighted users identify as visually complex are complex for visually impaired users as well, from a Web accessibility perspective. We aim to develop a heuristic framework that will be used for describing Web page's visual complexity and as guidelines for transcoding a Web page into a less visually complex and more accessible one.
