Abstract:
1. A locating device configured to operatively communicate with a pointing device and a computing device for locating the pointing device, the pointing device including an image pickup section for capturing a plurality of images, and a gyroscope for measuring an angular rate of the pointing device, the pointing device being operable to generate and output current coordinate data associated with an orientation of the pointing device when at least one of the images contains infrared light from a light source module, the computing device being configured to display a cursor on a display unit, said locating device comprising: a wireless communication module that is configured to receive the current coordinate data and the angular rate from the pointing device; and a data processor coupled to said wireless communication module, said data processor being configured to generate a cursor signal based on one of the current coordinate data and the angular rate, and to transmit the cursor signal to the computing device so as to enable the computing device to move the cursor according to the cursor signal; wherein said data processor is configured to generate the cursor signal based on the current coordinate data when the current coordinate data is received, and based on the angular rate when the current coordinate data is not received.
