Abstract
A three-dimensional ultrasonic position control device suitable for controlling computer displays or robot movements is disclosed. More specifically, signals from an ultrasonic transmitter are received by multiple receivers. The received signals are processed by a processing circuit which provides signals to a computer system for use in controlling a computer display or a robot. This system is particularly adapted to use inexpensive components to provide for a low cost mass producible control device.
