  • Method for distinguishing between edge swipe gestures that enter a touch sensor from an edge and other similar but non-edge swipe actions
    Patent number: 9395852
    Abstract: A method for detecting and tracking a single finger or multi-finger gesture referred to as an edge swipe gesture that originates from an edge of a touch sensor and which is distinguished from normal touch sensor operations such as cursoring, wherein the edge swipe gesture generates detection and tracking data having an immediate change, whereas touchdown or movement towards and then away from an edge of the touch sensor will generate data that is different from the edge swipe gesture.

  • High resolution non-ghosted gestures
    Patent number: 9086769
    Abstract: A method of performing a two-finger gesture when the absolute position of the fingers does not need to be known in order to perform the gesture. A touch sensor may provide a false or ghosted position and a real position for each actual finger on the touch sensor. The real position for each finger is located by finding a strongest signal when performing a short aperture measurement relative to one side of the touch sensor so that the direction of a rotation gesture can be determined. The position of fingers in single finger and multi-finger gestures may be determined using de-ghosted weighted average and weighted absolute deviation calculations.
