Patent ID: 8451223

Claim:
A pointing device comprising: an image sensing unit to sense at least one image pattern among a plurality of image patterns arranged in a display region of a display device, to determine first position information; an inertial sensing unit to sense a motion of the pointing device using at least one of acceleration information and angular velocity information and to determine second position information based on the sensed motion; and a coordinate determining unit to determine a first set of coordinates on the display device using the first position information and the second position information, wherein at least one of the image patterns displayed on the display region are stored beforehand and are formed by at least one of a visible ray, an infrared ray, and an ultraviolet ray, wherein all of the image patterns are arranged in image frames that are displayed at predetermined time intervals, among the image frames displayed on the display region, wherein at least one of the image patterns displayed on the display region include one or more different image codes.
