Gesture sensing module and method as well as electronic apparatus

[0042] Embodiments of the present disclosure provide a gesture sensing module, method and electronic device thereof. The gesture sensing module, method and electronic device thereof may have at least one light emitting unit and at least one light sensor. The central optical axis of the light beam emitted by the light emitting unit forms a non-zero included angle with the normal vector of the substrate, so that the light intensity of the light beam emitted by the light emitting unit does not concentrate on the exact center of the sensing area. Therefore, the light sensor can directly judge the gesture of the user through the change of the sensing signal within the sensing time. Since the light intensity of the light beam emitted by the light-emitting unit is not concentrated in the center of the sensing area, when the user's hand moves from left to right or from right to left, the sensing signal acquired by the light sensor It is an asymmetrical signal, so the control circuit can
