Abstract
A cursor control device for use with a three-dimensional stereoscopic image display system comprises a housing defining a volume corresponding to a displayed three-dimensional volume, and a joystick operable by the user for moving and positioning a cursor in the displayed three-dimensional volume. The joystick has a knob which is movable within the volume defined by the housing so as to designate desired positioning and movement of the cursor within the displayed three-dimensional volume. There is, at any given time, both positional and movement congruency between the position and movement of the knob and position and movement, respectively, of the cursor.
