Abstract
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. A laser beam is emitted from the gun only when the gun is pointed at a game video screen. Green and red LED'"'"'s on the gun indicate the presence of a friend or foe character or avatar. The gun includes a zoom control that affects the screen representation of the player'"'"'s view and visibility in the game scenario. 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.
