1. A targeting game machine comprising:

  • a display monitor for displaying a target;

    at least one targeting device;

    at least three transmitters for emitting infrared light signals, wherein at least three transmitters are mounted on the at least one targeting device;

    at least three photodiode receivers capable of detecting the light signals from said transmitters, wherein the receivers are mounted about the display monitor;

    a receiver circuit electrically connected to said receivers, wherein the receiver circuit generates signals in relation to the intensity of the infrared light signals detected by the receivers, the generated signals representing the distance of the transmitters from the receivers; and

    a processor for processing the signals to determine the three-dimensional coordinate position and orientation of the targeting device with respect to the display monitor.
