<p>A motion gesture sensing module according to the present invention comprises a light sensor unit having at least two or more photo detectors for detecting light reflected from a subject and a light source that emits light, and by putting an optical block in a light receiving path of the light sensor unit so as to separate the detectable area of each light detector, the motion gesture sensing module can distinguish the motion or gesture of the subject based on an output of the light sensor unit. A motion gesture sensing method according to the present invention is a non-contact motion sensing method which enables light emitted from the light source and light reflected by the subject to be received through at least two or more light detectors and enables the motion of the subject to be distinguished by comparing the output value of each light detector, wherein the detectable area of the light detector is separated and the light reflected by the subject is received to sense the motion of the subject. The present invention provides a motion gesture sensing module of low cost, low electric power and a subminiature size. Additionally, the motion gesture sensing module and the sensing method according to the present invention can sense the relative motion or gesture of the subject, sense a space touching function such as clicking a mouse, and distinguish whether the subject is close, thereby being capable of implementing all functions that existing proximity sensors have, including proximity sensing, reading mode, and power saving functions.</p> |
