Eleni Michailidou of the Web Ergonomics Lab has graduated from the University of Manchester with the Degree of Doctor of Philosophy in the Faculty of Engineering and Physical Sciences. The thesis for the degree is entitled Visual Complexity rankings and Accessibility Metrics. The thesis describes the development of a statistical model, based on the density and diversity of Web page structural elements such as tex, tables, and images, to predict a sighted users' perception of Web page visual complexity. The model was incorporated into the aDesigner accessibility tool to automatically analyse a Web page for its complexity. For each Web page a complexity score determined the page's level of visual complexity and an overlay heatmap mimicked a users's visual complexity perception by noting the areas that are most visually complex.
