Three-dimensional cursor control device
First Claim
1. In a system for displaying a three-dimensional stereoscopic image of an object positioned in a displayed three-dimensional volume;
- a cursor control device comprising a housing defining a volume corresponding to the displayed three-dimensional volume, said device further comprising joystick means operable by the suer for moving the positioning a cursor in the displayed three-dimensional volume, wherein said joystick means includes a knob which is movable from one position to another within the volume defined by said housing;
said joystick means further comprising a base portion, an upper portion mounted on said base portion, and a shaft having a first end connected to said upper portion and a second end, said knob being positioned on said second end of said shaft;
said device further comprising potentiometer means responsive to movement of said upper portion relative to said base portion for generating an electrical signal corresponding thereto, said potentiometer means comprising a resistance strip disposed beneath said upper portion and a potentiometer slider extending from said upper portion to said resistance strip.

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.

10. In a system for displaying a three-dimensional stereoscopic image of an object positioned in a displayed three-dimensional volume.
a cursor control device comprising a housing defining a volume corresponding to the displayed three-dimensional volume, said device further comprising joystick means operable by the user for moving and positioning a cursor in the displayed three-dimensional volume, wherein said joystick means includes a knob which is movable from one position to another within the volume defined by said housing; -
said device further comprising a guide assembly positioned at a given end of said housing, said joystick means further comprising a shaft having a first end connected to said guide assembly and a second end, said knob being positioned on said second end of said shaft; said guide assembly comprising potentiometer means responsive to the position of said knob in the volume defined by said housing for generating first and second electrical signals corresponding to the position of said knob relative to first and second dimensions, respectively, said device further comprising additional potentiometer means for generating a third electrical signal corresponding to the position of said knob relative to a third dimension; said device further comprising a platform on which said guide assembly is mounted, said additional potentiometer means comprising a resistance strip disposed below said platform and a potentiometer slider extending from said platform to said resistance strip. - View Dependent Claims (11, 12, 13)
