Yu, W., Reid, D. and Brewster, S.A. (2002) Web-based multimodal graphs for visually impaired people. In: 1st Cambridge Workshop on Universal Access and Assistive Technology (CWUAAT), Cambridge, England, 25-27 March 2002, ISBN 1852335955




This paper describes the development and evaluation of Web-based multimodal graphs designed for visually impaired and blind people. The information in the graphs is conveyed to visually impaired people through haptic and audio channels. The motivation of this work is to address problems faced by visually impaired people in accessing graphical information on the Internet, particularly the common types of graphs for data visualization. In our work, line graphs, bar charts and pie charts are accessible through a force feedback device, the Logitech WingMan Force Feedback Mouse. Pre-recorded sound files are used to represent graph contents to users. In order to test the usability of the developed Web graphs, an evaluation was conducted with bar charts as the experimental platform. The results showed that the participants could successfully use the haptic and audio features to extract information from the Web graphs.
