Abstract:
An interactive projection apparatus and a touch position determining method thereof are provided. The invention adopts such a scheme of defining the effective touch area according to the coordinate information of the positioning pattern and judging whether or not the light spot is located in the effective touch area. If the light spot is located in the effective touch area, the position of the light spot is taken as the touch position of an input tool.
