A three-dimensional position and motion telemetry computer input apparatus
includes a wireless transmitter configured to repeatedly transmit encoded
signals in at least three mutually distinct directions. A set of at least
three unidimensional signal detectors are disposed in spaced relation to
one another and configured to repeatedly detect in real-time, the
amplitude of the encoded signals incident thereon. A controller is
configured to repeatedly capture data corresponding to the signal
amplitude, in real-time. A calculation engine repeatedly determines the
3-D position of the transmitter using the captured data. At least one
output port coupled to the calculation engine, repeatedly transmits the
3-D position of the transmitter to a data consumer in real time.
