The invention provides a handheld pointing device and a cursor locating method of the handheld pointing device. The cursor locating method of the handheld pointing device includes: when the handheld pointing device updates the current-used first inclined angle to the second inclined angle, retrieving the first image frame of the reference point; calculating the first pointing coordinate according to the imaging position of the reference point in the first image frame and the first inclined angle; calculating the second pointing coordinate according to the imaging position of the reference point in the first image frame and the second inclined angle; retrieving the second image frame of the reference point so as to calculate the third pointing coordinate according to the imaging position of the reference point in the second image frame and the second inclined angle; and calculating the cursor location according to the third pointing coordinate, the first pointing coordinate and the second pointing coordinate, and correspondingly generating the cursor parameter which controls the cursor to be located on the displaying position.
Description
technical field [0001] The invention relates to a positioning method of a pointing device, and in particular to a cursor positioning method of a hand-held pointing device. Background technique [0002] Hand-held pointing devices, because they can calculate the pointing coordinates of the handheld pointing device by analyzing the position of the reference point in the sensed image area, and transmit the pointing point coordinates to the game console for related game operations, have been adopted Widely used in various interactive remote control games, such as light gun games, baseball games and tennis games. [0003] The distance between the image sensor installed on the hand-held pointing device and the display screen and the rotation angle of the hand-held pointing device when capturing images will affect the calculation of pointing coordinates. Therefore, in order to increase the hand-held feel of the handheld pointing device, the handheld pointing device is generally equ...
