Zusammenfassung:An embodiment of the invention relates to a method for sensing a displacement of a pointing device, like a mouse. The pointing device includes at least one light source configured to illuminate a surface, at least one first secondary photodetector, at least one second secondary photodetector and at least one primary photodetector. Each individual value of photodetectors is weighted and compared to sense the displacement of the pointing device by comparing a plurality of storage elements.
