Access to Mathematics for Visually Disabled Students Through Multimodal Interaction

Mathematics relies on visual forms of communication and is thus largely inaccessible to people who cannot communicate in this manner because of visual disabilities. This paper outlines the Mathtalk project, which addresses this problem based on the use of computers to produce multi-modal renderings of mathematical information. This example is unusual in that it is essential to use multiple modalities because of the nature and the difficulty of the application. In addition, the emphasis is on non-visual and hence novel modalities. Access to mathematics 3
