A three-dimensional position and motion telemetry computer input apparatus includes a wireless movable element 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 movable element using the captured data. At least one output port coupled to the calculation engine, repeatedly transmits the 3-D position of the movable element to a data consumer in real time.
