Abstract
In one aspect of the present invention, there is provided a video game system including a game controller, a video display and a hand-held control unit. The game controller is coupled to the control unit and the video display. The control unit houses an accelerometer that senses the tilt of the control unit with respect to an axis. The accelerometer produces an acceleration signal indicating the tilt of the control unit with respect to the axis. The game controller processes the acceleration signal to control the movement of a game character on the video display.In another aspect of the present invention, there is provided a video game system that further includes a light sensor housed in the control unit. The light sensor detects one or more light pixels from the video display and produces a detection signal to the game controller. The game controller determines from the detection signal the light pixels detected from the video display.
