Abstract

An apparatus, system, and a method for providing more realistic shooting input for shooting video games on computers or similar devices is provided. The apparatus may be comprised of a mock shooting device, such as a gun, having a lighting device containing a plurality of light sources. The apparatus may also include a screen device for displaying visual target objects of a video shooting game, at which a game player can shoot at with the mock shooting device, a video camera that captures video images of the mock shooting device, and a computing device that computes the hit position of the mock shooting device on the screen device based on the captured video images. The determined hit position can then be fed to the video shooting game software run by the computing device which can determine if a visual target object is actually hit or not, and reacts accordingly. The system and method can be extended to a plurality of game players using mock shooting devices with different colored lighting devices so that a plurality of hit positions for different colors may be determined.
