INPUT DEVICE COMPRISING GEOMAGNETIC SENSOR AND ACCELERATION SENSOR, DISPLAY DEVICE FOR DISPLAYING CURSOR CORRESPONDING TO THE MOTION OF THE INPUT DEVICE, AND, CURSOR DISPLAY METHOD THEREOF

摘要

An input device with a geomagnetic sensor and an acceleration sensor, a display device for displaying a cursor according to motion of the input device, and a cursor display method using the same are provided to prevent shaking of the cursor owing to noise by gradually moving a position of the cursor according to a change of a pitch/yaw angle. An operator(120) operates a first relative angle corresponding to pitch angle information and a second relative angle corresponding to yaw angle information. A coordinate calculator(130) calculates coordinates gradually changed according to the change of the first and second relative angles. A display part(140) displays the cursor to the position corresponding to the calculated coordinates. The coordinate calculator calculates the calculated coordinates as the final coordinates if the difference between the calculated coordinates and the previous coordinates is over the predetermined number of pixels, and calculates the calculated the previous coordinates as the final coordinates if not.
