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 operate a variably operable system to create a virtual reality system. The triangulation means may comprise at least three ultrasound emitters cooperating with ultrasound receivers located on a body moving in the three-dimensional region. The signals are produced from multiplexed frequencies and/or intermediate signals may be projected using a triaxial accelometer.
