Claim 0:
1. An interactive projection system, comprising a projector and a touch interactive light source device, wherein:
the projector comprises a projection optical engine, a camera module, and a control module, the projection optical engine is configured to emit a projection beam toward a projection surface to form a projection range on the projection surface;
the touch interactive light source device comprises at least one infrared light source module and a wireless signal transmission module, wherein the at least one infrared light source module is configured to generate an infrared light curtain parallel to the projection surface, and is electrically connected to the wireless signal transmission module; and
the control module is electrically connected to the projection optical engine and the camera module, and controls the touch interactive light source device through the wireless signal transmission module, so that the touch interactive light source device is placed in a recommended installation position and the interactive projection system is in an interactive mode,
wherein when an object approaches the projection surface and contacts the infrared light curtain, the control module receives an infrared light beam reflected by the object through the camera module, and identifies a position of the object or a touch position of the object corresponding to the projection range according to the infrared light beam.
