Abstract

An acoustic tracking system is provided that includes a mobile device including a plurality of receivers that receives an acoustic signal from each of three transmitters disposed in a fixed, non-planar relationship with respect to each other, where the three transmitters are coupled to a transmitting device. The system also includes a processing component that determines based on the acoustic signals received at the plurality of receivers a position of the transmitting device in a multidimensional space. The system also includes an application controller that affects operation of an application based on a determined position of one or more transmitters of the three transmitters.

First claim

What is claimed is:

1. An acoustic tracking system, comprising:
a mobile device including a plurality of receivers that receives an acoustic signal from each of at least three transmitters disposed in a fixed, non-planar relationship with respect to each other, wherein the at least three transmitters are coupled to a transmitting device;
a processing component that determines, based on the acoustic signals received at the plurality of receivers, a position of the transmitting de…
