ABSTRACT:
A three-dimensional computer image variable perspective display system provides for the real-time perspective control of a three-dimensional computer generated image controlled by the head movements of a computer operator viewing the image. The system includes an ultrasonic transmitter module worn on the head of the computer operator, a set of ultrasonic receivers mounted on or near the computer display monitor, and a computer interface unit. The ultrasonic transmitter transmits sound waves towards the display monitor which are detected by the ultrasonic receivers and processed by the computer interface unit. The computer interface unit calculates the elapsed times between the transmission and reception of the sound waves and converts this information into digital data words. The quantative magnitude of these data words represent in direct proportion, the instantaneous distance between the ultrasonic transmitter and the ultrasonic receivers. This distance information interacts with rotational axis algorithms used to control the three-dimensional display to cause the image to change it's perspective view in correspondence to the movement of the computer operator's head, in a manner exactly analogous to viewing three-dimensional objects in nature.
