Simulated Gun Shooting and Target Position Sensing Apparatus and Method

摘要

The present invention comprises a transmitter unit having at least one infrared (IR) transmitter, a target screen, a plurality of photodiode sensors disposed in a spaced apart relationship about the target screen, and receiver circuitry connecting the photodiode sensors together. The transmitter unit continuously emits an IR signal, which is detected by the photodiode sensors. The receiver circuitry then triangulate the position of the transmitter unit by calculating the differential distances between each of the photodiode sensors and the transmitter unit. The receiver circuitry is able to dynamically update the position of the transmitter unit because the transmitter unit continuously emits an IR signal. The transmitter unit is able to simulate a “shot” in a number of different ways, including updating the packet update rate or altering the data packet preamble. No return signal is necessary for the transmitter unit to confirm the “shot.”

1) A simulated gun target and shooting system, comprising:
a target display screen; a plurality of sensors disposed about said target display screen in a planar configuration; at least one transmitter unit having at least one emitter adapted to continuously emit pulsed light signals and CPU; a receiver system electrically connected to said sensors, wherein said receiver system is adapted to calculate the distance between said transmitter unit and said sensors based upon the incidence of said pulsed light signals detected by said sensors; a processor adapted to calculate the three-dimensional position of the transmitter unit based upon said calculated distances; wherein said target display screen is adapted to display an aiming vector position from said transmitter unit based upon the calculated three-dimensional position of the transmitter unit.
