Abstract
A shift control method is used with a pen-shaped pointing device and a controlled device. Firstly, shift information, tilt angle information and rotating angle information in response to a configuration change of the pointing device relative to a supporting plane are sensed. Then, a shift estimation operation is performed by the controlled device according to the shift information, the tilt angle information and the rotating angle information, thereby acquiring a position-compensating data. If the pointing device is in contact with the supporting plane, a moving trajectory of the pointing device displayed by the controlled device is adjusted according to the position-compensating data.
