| Zusammenfassung: | An input detecting projector and an input detecting method thereof are provided. Firstly, the input detecting projector reciprocately projects a visible light and an invisible light to a surface at the same time. There is a projecting distance between the surface and the input detecting projector. Afterward, the input detecting projector receives an invisible reflection light reflected from an input object, and determines an input distance between the input object and the input detecting projector. The input detecting projector then generates a control signal based on the input distance and location information of the input object related to the surface. |
