Abstract

A method for gesture detection comprises pre-processing and main-processing steps, wherein the pre-processing comprises emitting light using a light emitting device (IR_LED) and generating of directional sensor signals (CH1, CH2, CH3, CH4) as a function of time by detecting a fraction of the emitted light reflected by means of a movable object (OBJ) using a directional light sensor array (LSA). The main-processing comprises calculating coordinates (x_coord, y_coord) as a function of time by using the directional sensor signals (CH1, CH2, CH3, CH4), being indicative of a position of the object (OBJ) with reference to a plane parallel to a principal plane of the light sensor array (LSA), and detecting a movement of the object (OBJ) depending on the timing of the coordinates (x_coord, y_coord).
