Optical Tracking

• An optical computer mouse uses a light-emitting diode (LED) to illuminate the surface beneath the mouse sensor to detect movement relative to a surface. They are generally less expensive than laser sensors, but cannot track on the same wide range of surfaces. The mouse cursor will move slightly more slowly than a laser mouse, but will generally track smoothly without jumping around. Depending upon the type of surface on which you are tracking, a mouse pad may be necessary.
