Method and device for optical gun interaction with a computer system

A device and a method for integrating an optical gun with a computer game system and within a computer game scenario are provided. The preferred embodiment includes an optical gun, or gun, with a communications interface, such as a USB interface, with the computer game system. The gun has sensors that sense when (1) a player is grasping a gun handle, or (2) the gun is holstered. The gun simulates a recoil force when a simulated round is fired. A battery is charged between game periods and drawn down during play. The gun may have bidirectional or unidirectional wireless communications with the computer game system, a battery charger and multi-channel radio carrier frequency auto detect. The gun can determine the nature of the game video screen. A video sampling or tapping wire may enable further enhanced features of the gun.
