Patent ID: 7188045

Claim:
A three-dimensional position and motion telemetry computer input apparatus, comprising: a wireless transmitter configured to repeatedly transmit pulsed optical signals in at least three mutually distinct directions; at least three uni-dimensional optical signal detectors disposed in spaced relation to one another; a discriminator coupled to said signal detectors, configured to repeatedly distinguish said pulsed optical signals from other signals; said signal detectors configured to detect the amplitude of the pulsed optical signals incident thereon, repeatedly in real-time; an analog to digital converter configured to repeatedly digitize, in real-time, signal amplitude data corresponding to the amplitude detected by said signal detectors; a controller configured to repeatedly capture, in real-time, the digitized signal amplitude data; a calculation engine configured to repeatedly determine the 3-D position of said transmitter, in real-time, by trilaterating said captured signal amplitude data; and at least one output port coupled to said calculation engine, said output port configured to repeatedly transmit the 3-D position of said transmitter to a computer in real-time.
