发明名称 Electromagnetic cursor control device for a computer display
摘要 The electromechanical controller, or cursor control device, consists of a solid surrounded by a flexible bladder, the solid and bladder being received within a housing. The bladder is freely moveable relative to the solid. Movement of the bladder is sensed by X and Y transducers to generate signals which may be employed to control the visual display of a computer. In one embodiment, the device is physically connected to the computer; in another embodiment, the device incorporates a wireless transmitter to broadcast signals to a receiver associated with the computer.
