Non-Speech Sound in Human-Computer Interaction: A Review and Design Guidelines

Abstract

Recent developments in computer technology make it possible to use sound more extensively in the computer interface than has hitherto been possible. This article describes research on uses of computer sound and suggests how sound might be used effectively by instructional and interface designers. After a review of some general principles of interface design and of basic research into auditory perception, the article examines two uses of sound: Earcons, whose purpose is to inform the user about the state of the system itself, and sonitization, whose purpose is to represent data generated by computer programs as sound. Both symbolic and iconic sounds are examined. The role of sound in virtual environments is also discussed with particular attention to its use in aircraft. Design guidelines are listed, and conclusions about needed research are offered.
