Video game system having a control unit with an accelerometer for controlling a video game
First Claim
1. 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.

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.
