Pointing device with solid-state roller
First Claim
1. A pointing device comprising:
- a housing for supporting a user'"'"'s hand;
a pointing sensor, mounted in said housing, for providing a pointing signal;
a contour on said housing for receiving a finger of said user, said contour having curvature in two directions;
a solid-state scrolling touch sensor in said contour for detecting movement of said finger along said contour.

Abstract
A solid-state roller on a pointing device with enhanced features. The solid-state design described herein allows the sensor to be placed on any shape of surface, such as one that has curvature in two directions. In one embodiment, a trench or downward curve contains sensors for detecting finger movement. The user'"'"'s finger can thus bend about a knuckle in a curved motion to activate the sensor, requiring little or no movement of the finger up and down. The solid-state sensors can be of one of a number of designs. In one embodiment, multiple electrodes are contacted by a finger as it moves. Each electrode is coupled to a capacitive detection circuit, for detecting the change in capacitance as the electrode is contacted by the finger.
