20150029099 | METHOD FOR CONTROLLING TOUCH AND MOTION SENSING POINTING DEVICE - A method for controlling a touch and motion sensing pointing device is disclosed. In the method, a touch on the pointing device is sensed through a touch sensing module. Whether or not a touch size of the touch is smaller than a predetermined size is determined when the touch is sensed. An output of coordinate signals of the pointing device is locked when the touch size of the touch is smaller than the predetermined size. Whether or not a persisting time of the touch is larger than a predetermined time is measured when the output of coordinate signals is locked. The output of coordinate signals is unlocked when the persisting time of the touch is greater than the predetermined time. A mouse-click signal is transmitted when the persisting time of the touch is smaller than or equal to the predetermined time. | 01-29-2015 |
