  • Patent number: 4654647
    Abstract: A finger operable electronic control apparatus includes a finger pad actuator mounted to a base so as to be movable in several directions. The position of the finger pad is sensed and utilized in the generation of electrical control signals. These control signals are used to control movement of a cursor or other image on an electronic display screen, as well as for other purposes. In one specific form, the base is generally horizontal and the finger pad is mounted by trapezoidal mounts for movement in first and second mutually perpendicular directions. In addition, the base is mounted to a supporting structure for movement in a direction which results in corresponding movement of the supported finger pad in the third direction. Movement of the finger pad in the first, second and third directions, as well as the rate of movement, may be sensed and utilized to generate electrical control signals.
