Using audio to enhance information tasks

This paper describes new audio capabilities that are not just technologies; it also reflects an understanding of how to use audio to support information tasks. The following assertions underlie these new capabilities: meaningful nonspeech sounds can function like words; sound design is a critical factor in the effective use of sound; sonification is an option for conveying information; sound can make visual attention significantly more efficient. We take a look at how these assertions combine to improve our abilities to process information.
