  • Patent number: 8963846
    Abstract: A cursor control method using a touchpad triggers an automatic movement signal for a cursor when an object moves from a first defined region into a second defined region of a two-dimensional touch sensor, or when an object stays in the second defined region for a preset duration after it moves from the first defined region into the second defined region, and define the automatic movement signal with the direction identical to that of the object moving into the second defined region, so that the cursor will keep moving in its last moving direction.

  • Publication number: 20100001966
    Abstract: A capacitive touchpad includes a controller, a plurality of scan lines and a plurality of sensor pads distributed over a one dimensional touch sensor. Each of the sensor pads is connected to the controller by a respective one of the scan lines to transmit a sensed value to the controller. The controller uses the sensed values and the positions of some of the sensor pads in an interpolation to determine the two dimensional coordinates of one or more touched positions. Based on the sensed values, the controller selects one or more of the sensor pads as one or more reference points for the interpolation.

  • Patent number: 7576732
    Abstract: A scroll control method using a touchpad comprises predefining a region on a touchpad, whereby a scroll function will be triggered by a landing of an object on the region, and terminated by a leaving of the object from the touchpad. During the scroll function is executed, the moving distance of the object sliding on the touchpad is calculated to determine a corresponding scrolling signal.
