ABSTRACT:
A device for selectively manipulating movement of a cursor on a computer display, as with the user's foot. The device comprising a housing, an elongated control stick member protruding through an opening defined in the top wall of the housing, and sensors for detecting movements of the bottom end of the control stick member. An annular guide member supports the control stick member in the housing for pivotable and longitudinally reciprocated motion under selective user control. A helical coil spring resiliently urges the control stick member longitudinally upward from the housing top wall to reposition the stick member after a user-initiated inward displacement.
