Audio location is a technique for performing accurate 3D location

sensing using off-the-shelf audio hardware. The use of off-the-shelf hardware allows

audio location deployment to be low-cost and simple for users, as compared

to other currently available centimetre-scale location sensing systems which have

significant custom hardware and installation labour requirements. Another advantage

of audio location is the ability to locate users who are not carrying any special

location-enabling “tag”, by using sounds that the user themselves can make such

as finger clicking. Described herein are the various design parameters for audio

location systems, the applicability of audio location for novel 3D user interfaces

based on human sounds, and a quantitative evaluation of a working prototype.
