Abstract
Each opto-mechanical pointing device includes a housing having a base that two or more rollers extend beyond to make contact with a surface. An optical module that includes a light source and a detector track the motion of the opto-mechanical pointing device directly or indirectly. Light reflecting off markings positioned opposite of each detector is used to determine the speed and distance traveled by an opto-electrical pointing device. Alternatively, the speed and distance traveled by an opto-electrical pointing device is determined by monitoring the tilt or rotation of the opto-mechanical pointing device with respect to the surface beneath the pointing device.
