MATHTALK: USABLE ACCESS TO MATHEMATICS
By Stevens, Robert D. Edwards, Alistair D. N. Department of Computer Science, The University of York, Heslington, York, UK; Information Technology and Disabilities, Vol 1, No 4Publication Date: November 1994
This article describes the design and development of the user interface to the "Mathtalk" program, which aims to give visually disabled readers an active reading of standard algebra notation. The authors introduce two main guiding principals in the design of the interface: 1) enhancing external memory; 2) control of information flow. Mathtalk uses structured browsing functions and a specially developed command language to achieve fast and accurate control of information flow which is vital for active reading. Finally they describe an audio glance (analogous with a visual glance at printed text), which they call algebra earcons (analogous with icons in Windows software) that enables readers to get a high level view of an expression and plan the reading process.
