Browsing the Web from a Speech-Based Interface

Abstract

The design of information presentation on the web is predominately visual-oriented. This presentation approach requires most, if not all, of the user's attention and imposes considerable cognitive load on a user. This approach is not always practical, especially for the visually impaired p ersons. The focus of this project i s to develop a prototype which supports web browsing using a speech-based interface, e.g. a phone, and to measure its effectiveness. The c ommand input and the delivery of web contents are e ntirely in vo ice. Audio icons are built into the prototype so that users can have better understanding of the original structure/intent of a web page. Navigation and control commands are available to enhance the web browsing experience. The effectiveness of this prototype is evaluated in a user study involving both normally sighted and visually impaired people. Useful lessons learnt from this experiment helps drive further research to a better speech-based interface.
