Abstract:
A pointing device having a moveable puck that moves in a predetermined field of motion by applying a lateral force thereto is disclosed. A first linear spring is attached to the puck, the first spring applying a first force to the puck at each location in the field of motion. A second linear spring is also attached to the puck, the second spring applying a second force to the puck at each location in the field of motion. The first and second springs return the puck to a predetermined location in the field of motion when the lateral force is not applied to the puck. The first linear spring is folded around a bending point and attached to a portion of the pointing device that is stationary with respect to the puck.
