Abstract: An exemplary embodiment of the present disclosure provides a handheld pointer device and a tilt angle adjustment method thereof. The tilt angle adjustment method includes the following steps. Images corresponding to the position of a reference point are captured as the handheld pointer device pointing toward the reference point to generate a plurality of frames. Whether the reference point has substantially moved is subsequently determined based on the plurality of frames. When determines that the reference point has not substantially moved, causes an accelerometer unit of the handheld pointer device to detect the accelerations thereof over various axes so as to update a first tilt angle being used currently to a second tilt angle, accordingly. The handheld pointer device may thus accurately and efficiently calculate the relative position of the reference point with the appropriate tilt angle of the handheld pointer device used.
