Claim Text:
1. A gesture sensing module, disposed on a substrate, comprising: at least one light emitting unit, providing a light to irradiate a sensing area, wherein a central optical axis of the light forms an angle with a normal vector of the substrate, and the angle is not equal to 0; at least one light sensor, sensing a reflection light which a target in the sensing area reflects the light, and generating a sensing signal according to the reflection light; and a control circuit, coupled to the light sensor and the light emitting unit, determining a traveling direction of the target according to the sensing signal; wherein the substrate has a inclined surface, and the light emitting unit is disposed on the inclined surface of the substrate, such that the angle formed by the central optical axis of the light and the normal vector of the substrate is not equal to 0.
