Patent ID: 8308558

Claim:
Apparatus for providing, in response to signals generated by a computer or video game system, tactile sensation to a user of said computer or video game system, said apparatus comprising: a hand-held game pad controller; where said hand-held game pad controller is adapted to be held by both of a user's hands simultaneously; a plurality of motors, disposed within said hand-held game pad controller, for selectively generating tactile sensation as vibrations; control circuitry, coupled to said plurality of motors, where said control circuitry is responsive to signals that are generated by said computer or video game system; where said signals correspond to action executing on said computer or video game system; where said control circuitry controls said plurality of motors, where at least two motors of said plurality of motors are controllable independently of each other; where said at least two independently controllable motors each has an offset mass attached to its shaft and each said offset mass is attached to nothing else, such that when each motor is activated, its shaft rotates, such that said at least two motors each generate vibrations via the rotation of each said offset mass attached to each said shaft; where the said rotation of each said offset mass occurs in only one direction; where the speed of said rotation of each rotating shaft of each of said at least two motors is independently changeable in real time; where said vibrations generated via the rotation of each said attached offset mass change in real time in accordance with said independently changing speed of rotation of said rotating shafts of said at least two motors; where said at least two motors generate vibrations simultaneously, wherein the simultaneous vibrations are of independent intensities with respect to each other; where said vibrations of said simultaneous independent intensities combine in said hand-held game pad controller into a simultaneous combination of vibrations; where said simultaneous combination of vibrations is felt in both hands of the user holding the hand-held game pad controller.
