Abstract
A virtual image display system includes a virtual image display device and a hand-held control device. The virtual image display device is coupled to the hand-held control device. The hand-held control device is configured to capture image information of the virtual image display device and analyze the image information to obtain relative angle information between the virtual image display device and the hand-held control device. The virtual image display device adjusts a pointing direction of a displayed virtual hand-held control device image according to the relative angle information.
