Compact pointing device
First Claim
1. A pointing system, comprising:
- (a) a moveable puck configured to move laterally within a puck field of motion (“
PFOM”
) in response to a user applying a lateral force thereto, the puck comprising a pressure sensing system configured to sense a first predetermined vertical pressure level applied by the user to the puck;
(b) a position detector configured to measure puck position within the PFOM as the puck is moved laterally by the user therewithin, the position detector further being configured to report the puck position to a processor configured to actuate or cause to be actuated tracking or movement of a cursor on a display, the tracking or movement of the cursor corresponding to lateral movement of the puck by the user within the PFOM; and
(c) a puck return mechanism attached to the puck and configured to return the puck to, or hold the puck in, a resting position within the PFOM when the user stops applying, or does not apply, vertical pressure to the puck;
wherein the system is configured actuate or cause to be actuated tracking or movement of the cursor on the display corresponding to lateral movement of the puck by the user within the PFOM when the user applies vertical pressure to the puck that is greater than or equal to the first predetermined vertical pressure level, and to cause the cursor to stop tracking or moving on the display when the user applies vertical pressure to the puck that is at least one of less than the first predetermined level and no vertical pressure.

Abstract
The pointing device has a moveable puck that moves over a surface in a puck field of motion. A position detector measures the puck position in the puck field of motion. In one embodiment, the puck includes a user sensor that detects an interaction between a user and the puck. A controller causes a cursor to move on a display in response to the puck moving in the puck field of motion when the user sensor senses the interaction between the user and the puck. The magnitude and direction of motion of the cursor is determined by the magnitude and direction of motion of the puck in the puck field of motion. In another embodiment, a restoring mechanism is provided that returns the puck to a predetermined area in the puck field of motion when the user releases the puck.
