1. An apparatus for providing an output signal for selectively controlling movement of visual pointer on a display screen, comprising:

  • a plurality of solid state capacitive fingertip sensor switches including a center switch surrounded by a plurality of peripheral switches, each switch actuable to an on/off state in response to detection of a user'"'"'s fingertip; and

    a control unit responsive to changes in the on/off state of one or more of the peripheral switches of the plurality of solid state capacitive fingertip sensor switches for generating the output signal designating a direction of movement of the visual pointer and further responsive to the on/off state of the center switch of the plurality of solid state capacitive fingertip sensor switches for generating the output signal designating a centering of the visual pointer as with a joystick.
