Abstract

The World Wide Web (Web) is a visually complex, dynamic, multimedia system that can be inaccessible to people with visual impairments. SADIe addresses this problem by using Semantic Web technologies to apply accurate transcoding to a range of Websites. This report presents a user evaluation that was performed using the SADIe system. Users were presented with a series of Web pages, some having been adapted using SADIe's transcoding functionality and others retaining in their original state. Participants were asked to provide answers to a fact based questions, allowing a quantitative comparison between access to transcoded and non-transcoded Web pages to be made. Statistical analyses using both randomization testing and t-tests indicate that SADIe can improve the time users can reach information within a Web page.
