Abstract
An interactive system includes a display, a processor and a remote controller. The display includes at least one reference beacon for providing light with a predetermined feature. The remote controller includes an image sensor configured to capture an image containing the reference beacon and calculates an aiming coordinate according to an imaging position of the reference beacon in the captured image. The processor calculates a scale ratio of a pixel size of the display with respect to that of the image captured by the image sensor and moves a cursor position according to the scale ratio and the aiming coordinate.
