A motion gesture sensing module includes a light source emitting light, and a light sensor unit including at least two optical detectors sensing light reflected from a subject, in which an optical block is disposed in a light receiving path of the light sensor unit and individually separates a detectable zone of each of the optical detectors, thereby determining a motion or gesture of the subject based on output of the light sensor unit. Further, a motion gesture sensing method is a contactless motion sensing method, in which a light source emits light, light reflected from a subject is received by at least two optical detectors, and output values of respective optical detectors are compared to determine a motion of a subject, thereby sensing motion gesture of the subject by individually separating a detectable zone of the optical detector and receiving the light reflected from the subject. |
