    Research output: Contribution to journalArticlepeer-review


    This paper describes the design of the user interface to the Mathtalk program, which aims to give visually disabled readers an active reading of standard algebra notation. The paper introduces the themes of enhancing external memory and control of information flow as the guiding principles behind the design of the user interface. Fast and accurate control of the information flow is vital for active reading. Mathtalk uses structured browsing functions and a specially developed command language to achieve this active reading. Finally, an audio glance called algebra earcons is introduced that enables readers to get a high-level view of an expression and plan the reading process.
