    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.

    Abstract: An optical object recognition system includes at least two beacons, an image sensor and a processing unit. The beacons operate in an emission pattern and the emission pattern of the beacons has a phase shift from each other. The image sensor captures image frames with a sampling period. The processing unit is configured to recognize different beacons according to the phase shift of the emission pattern in the image frames.

    Abstract: An optical tracking device includes a light source, an image sensor and a processing unit. The light source emits light at a lighting frequency. The image sensor outputs an operating image when the light source is being turned on and outputs a background image when the light source is being turned off. The processing unit is configured to obtain background information from the background image, calculate a differential image of the operating image and the background image, obtain object information from the differential image and compare the background information and the object information thereby removing background noise.
