Abstract
A pointing device includes two lenses with wide and narrow view angles respectively. In a short distance range, the pointing device utilizes the lens with wide view angle to increase visible range. In a long distance range, the pointing device utilizes the lens with narrow view angle to increase size of a formed image of a reference point. In addition, the pointing device senses images through both of the lenses with wide and narrow view angles to obtain rotational information. The pointing device can provide not only positional information but also angular information.
