1. An optical sensor arrangement, comprising at least two light sensors for providing at least two sensor signals, and an evaluation circuit that comprises an input coupled to the at least two light sensors and is designed to generate an entry vector indicating the position of an object relative to the at least two light sensors at the start of a gesture and an exit vector indicating the position of the object relative to the at least two light sensors at the end of the gesture, wherein the first coordinate of a vector is a north to south strength and the second coordinate of the vector is an east to west strength.
