ABSTRACT:
A cursor control device with four (4) pins in an orthogonal array supported by elongated beams. Mounted above the pins is a palm shaped surface. When the palm shaped surface is depressed, it presses downward on one or more of the orthogonal pins which deflect the supporting beams downward toward a light emitter and sensor. The deflection of the beam changes the intensity of the light reflected off the beam which is sensed by the light sensor resulting in a change in electrical signal which is used to control cursor movement on a computer display.
