    Abstract: A handheld pointing device includes a main body, an image sensing module, an acceleration sensing module and a processing circuit. The image sensing module is disposed in the main body and configured to capture an image comprising at least one reference light source and accordingly generate an optical sensing signal. The acceleration sensing module is disposed in the main body and configured to sense an acceleration value in each one of two dimensions; wherein the acceleration sensing module outputs an acceleration sensing signal if an absolute value of the summation of the two acceleration values in two dimensions is located within a predetermined acceleration range. The processing circuit is configured to receive the optical sensing signal and the acceleration sensing signal and accordingly generate an output signal.

    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.
