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.

Abstract: An optical touch device configured to cause a display surface to from a touch surface. The optical touch device includes a non-visible lighting element, a non-visible sensing element, and a correction element. The non-visible lighting element is adjacent to the display surface and forms a non-visible light curtain in front of the display surface. The non-visible lighting element is disposed in front of the display surface and has a sensing area covering the display surface. The correction element is disposed on the display surface and includes a bottom layer placed on the display surface and a plurality of reflecting blocks disposed on the top surface of the bottom layer. The correction element of the optical touch device has long-life. A correction method for an optical touch device is also provided.

Abstract: The invention provides a projector, a color wheel protection circuit, and a color wheel protection method. The projector includes a color wheel, a light source, a controller, and a protection circuit. The light source is controlled by a light source control signal to provide an illumination beam to the color wheel. The controller is used for providing the light source control signal to the light source. The protection circuit includes a resetting signal generator and a logic operator. The resetting signal generator is used for generating a resetting trigger signal according to the rotation speed of the color wheel, and generating a resetting output signal according to the resetting trigger signal. The logic operator is used for receiving the light source control signal and the resetting output signal, and resetting the light source control signal according to the resetting output signal.
