Abstract
A pointing device using proximity sensing is described. In an embodiment, a pointing device comprises a movement sensor and a proximity sensor. The movement sensor generates a first data sequence relating to sensed movement of the pointing device relative to a surface. The proximity sensor generates a second data sequence relating to sensed movement relative to the pointing device of one or more objects in proximity to the pointing device. In embodiments, data from the movement sensor of the pointing device is read and the movement of the pointing device relative to the surface is determined. Data from the proximity sensor is also read, and a sequence of sensor images of one or more objects in proximity to the pointing device are generated. The sensor images are analyzed to determine the movement of the one or more objects relative to the pointing device.
