Abstract
A pointing input device and method, a pointer control device and method, and an image pattern generation device and method which move a mouse pointer displayed in a display region according to the movement of a location pointed at by the pointing input device. The pointing input device includes an image reception unit capturing an image pattern, which is displayed in a display region of a perceived size and based on which the scope of the display region is sensed, and sensing the scope of the image pattern; a coordinate extraction unit extracting coordinates of a location pointed at in the display region based on a center of the sensed scope of the image pattern; and a transmission unit transmitting the extracted coordinates to a pointer control device which controls a mouse pointer displayed in the display region.
