APPARATUS FOR CALCULATING POINTER MOVEMENT VALUE AND METHOD FOR CORRECTING POINTER MOVEMENT VALUE AND VARIATION OF ANGLE, 3D POINTING DEVICE USING THE SAME

摘要

A pointer moving value computing device, a posture amount of an angle change compensation method and a three-dimensional pointing device using the same for reducing fine vibration of the pointer are provided to prevent the pointing device forwarding to a specific direction. A sensor module(210) measures a posture angle. A processor(220) calculates the posture amount of angle change based on the measured posture angle. The processor produces the pointer moving value. When the posture amount of angle change is the positive number and negative number, the pointer moving value differently is corrected by the processor. A memory(230) stores the program and data required for the processing task of the processor.
