Abstract
A system is provided for tracking the three-dimensional position of an object within a three-dimensional region by triangulation techniques to generate signals corresponding to such three-dimensional positions. The signals may be used to drive a music synthesizer. Triangulation may be by the use of at least three spaced apart ultrasound emitters cooperating with ultrasound receivers located on a body moving in the three-dimensional region. The position of each ultrasound receiver is calculable by triangulation from data from ultrasound pulses received by the receiver from the emitters. A sound map may be made of the region so that similar signals may drive the synthesizer differently for different sub-regions.
