Abstract
A method utilized in a three-dimensional pointing system is provided according to the present invention. The three-dimensional pointing system includes a pointing device, a sensor array, and a display panel, wherein the sensor array is embedded within the display panel. The pointing device projects a pointer onto the display panel to form a projection image, and the sensor array accordingly generates a sensed image which includes the projection image. The method determines at least one space status information based on the sensed image.
