Abstract: | In this paper we describe a prototype spatial audio user interface for a Global Positioning System (GPS). The interface is
designed to allow mobile users to carry out location tasks while their eyes, hands or attention are otherwise engaged. Audio
user interfaces for GPS have typically been designed to meet the needs of visually impaired users, and generally, though not
exclusively, employ speech-audio. In contrast, our prototype system uses a simple form of non-speech, spatial audio. This
paper analyses various candidate audio mappings for location and distance information. A variety of tasks, design considerations,
design trade-offs and opportunities are considered. The findings from pilot empirical testing are reported. Finally, opportunities
for improvements to the system and for future evaluation are explored. |
