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.
