ABSTRACT:
A mouse for use in a video display system for controlling cursor movement on a display screen provided with feedback means which produces resistance to the motion of the mouse as the cursor moves across predetermined areas of the display screen. In its most straight forward realization it comprises an electromagnet and control circuit which operates independently of the pickup and location sensing control of the mouse to produce a magnetic field which acts cooperatively with a substantially planar magnetic surface to produce a resistance to the motion of the mouse when energized.
