Some addressed issues in projected reality are location acquisition, limited work space, and geometric distortion. This paper proposes a low-cost, robust, fast, and simple method for handling addressed problems using infrared camera in Nintendo's Wiimotes and a pan-tilt camera head. Two Wiimotes are attached on both horizontal and vertical axes of a portable projector mounted on a pan-tilt camera head. Hence, it can detect 4 infrared LEDs on the corners of a display surface in perspective projection volume. The augmented images are wrapped to fit the display area. To increase the system workspace, a pan-tilt camera head is used to track the display surface. While the display surface or the projector moves, a proposed fast location tracking algorithm between two Wiimotes is implemented. Experimental results demonstrate the ability of real time location tracking at 97 fps that is more than the refresh rate of typical projector. Finally, the active location tracking using the pan-tilt camera head can give workspace more than 36 times of the normal perspective projection workspace.
