INTERACTIVE PROJECTION SYSTEM, PROJECTOR THEREOF, AND CONTROL METHOD THEREOF

摘要

The present invention discloses an interactive projection system including a pointing device and a projector. The pointing device is used to generate a light spot. The projector includes a projecting module, an image capturing module, and a processing module, and the projector includes a built-in operating system. The operating system includes a plurality of applications with graphical user interfaces. The projecting module projects a projected image being present of the operating system onto a screen. The image capturing module captures an image generated by projecting the light spot onto the screen. The processing module calculates a coordinate of the light spot according to the above-mentioned image, and determines whether the light spot has stayed on the graphical user interface associated with one of the applications on the projection screen, so as to execute the application corresponding to the light spot.
