ABSTRACT:
An apparatus for providing an output signal for selectively controlling movement of a visual pointer on a display screen is disclosed. A plurality of solid state capacitive sensor switches are arranged in a two-dimensional array. Each of the switches is actuable in response to the positioning of a finger of a user to an on/off state. A control unit responsive to the on/off state of each of the plurality of solid state capacitive sensors generates an output signal that selectively controls the movement of the visual pointer.
