Abstract:
A video game system comprising:a game controller; a hand-held control unit coupled to the game controller and housing an accelerometer and a light sensor, the accelerometer sensing tilt of the control unit with respect to an axis, the accelerometer producing an acceleration signal indicating the tilt of the control unit with respect to the axis, the game controller processing the acceleration signal to control the movement of a game character on a video display coupled to the game controller and further processing the acceleration signal to control directional navigation of the game character through a game environment, said navigation corresponding to the tilt of the hand-held control unit, the light sensor detecting one or more light pixels from the video display corresponding to a direction in which the hand-held control unit is pointing, the light sensor producing a detection signal to the game controller, the game controller determining from the detection signal the light pixels from the video display detected by the light sensor.
