ABSTRACT:
A track ball control system which is attachable to a computer system that has a display screen on which a cursor is positionable, including at least one track ball regulator for providing physical control of the position of the track ball in response to signals from the control system. These signals depend on the location of the cursor on the display screen and cause the track ball to change in movement. This change in movement may be a vertical change, and/or an azimuthal change. The operator does not control this change in movement except indirectly by knowingly or unknowingly positioning the cursor in a position which causes the signals to be sent to the track ball.
