description In a method for sensing a displacement of a pointing device, like a mouse, said 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 the photodetectors is weighted and compared such as to sense said displacement of the pointing device.
