The audio abacus: representing numerical values with nonspeech sound for the visually impaired

Point estimation is a relatively unexplored facet of sonification. We present a new computer application, the Audio Abacus, designed to transform numbers into tones following the analogy of an abacus. As this is an entirely novel approach to sonifying exact data values, we have begun a systematic line of investigation into the application settings that work most effectively. Results are presented for an initial study. Users were able to perform relatively well with very little practice or training, boding well for this type of display. Further investigations are planned. This could prove to be very useful for visually impaired individuals given the common nature of numerical data in everyday settings. Categories and Subject Descriptors J.0. [Computer Applications]: General General Terms Design, Experimentation, Human Factors. Keywords Data sonification, auditory display, visually impaired users, value estimation.
