  • 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.
