Patent ID: 7679600

Claim:
A pointing device comprising: a moveable puck that can be positioned at any location in a predetermined field of motion by applying a lateral force thereto; a first linear spring attached to said puck, said first spring applying a first force to said puck at each location in said field of motion; a second linear spring attached to said puck, said second spring applying a force component to said puck at each location in said field of motion, and a bending post in a stationary position with respect to said puck, wherein the bending post is located outside of said field of motion, said bending post to contact an intermediate portion of said first linear spring to bend said first linear spring in a folded configuration at approximately a 90 degree angle around the bending post when the puck is in a resting position, wherein a first end of said first linear spring is attached to a stationary point located outside said field of motion such that a portion of the spring substantially follows a path adjacent to a perimeter of said field of motion of said puck, wherein said bending post further maintains a consistent location of a bending point for all positions of said puck within said field of motion.
