Abstract

An electronic game controller with motion-sensing capability includes an inertia sensing and wireless transmission unit, an image sensing unit and a control unit. The image sensing unit extracts and recognizes the images of the profile of the user'"'"'s body to generate signals indicative of the displacement or specific postures of the user. The inertia sensing and wireless transmission unit senses the motions of the user'"'"'s body to generate signals indicative of the rotation, rhythmic motions, swing or force of the user'"'"'s body. The control unit receives the signals and integrates them to generate control signals, thereby controlling the marker on the display picture of the electronic game. With the cooperation of the image sensing unit and the inertia sensing and wireless transmission unit, various motions or exercising states of the user can be sensed, thereby providing the user with a more complete and exquisite operating interface for the electronic game.
