Abstract
In an input apparatus, an input system includes a displaceable member movable in an operational zone and a tracking surface that moves in correlation with movement of the displaceable member. An optical sensor has a field of view of at least a portion of the tracking surface during movement of the displaceable member in the operational zone and generates optical data in response to light received from the tracking surface. A processing system produces motion measures indicative of movement of the tracking surface from the optical data. In an input method, optical data is generated in response to light received from a field of view of at least a portion of a tracking surface that moves in correlation with movement of a displaceable member during movement of the displaceable member in an operational zone. Motion measures indicative of movement of the tracking surface are produced from the optical data.
