Method for distinguishing between edge swipe gestures that enter a touch sensor from an edge and other similar but non-edge swipe actions

摘要

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.

1. A method for distinguishing between an edge swipe gesture and other touch functions on a touch sensor that detects at least one pointing object, said method comprising:
(1) providing a capacitance sensitive touch sensor having an edge around a perimeter thereof; (2) detecting at least one pointing object by the touch sensor in a boundary zone adjacent to the edge of the touch sensor, wherein the at least one pointing object has slid onto the touch sensor from a location that is off the touch sensor; (3) generating finger detection and position tracking data for the at least one pointing object; and (4) analyzing the finger detection and position tracking data, wherein finger detection and position tracking data that shows a pause in movement of the at least one pointing object immediately after detection in the boundary zone is characterized as a non-edge swipe gesture, wherein finger detection and position tracking data that shows immediate movement of the at least one object immediately after detection in the boundary zone is characterized as an edge swipe gesture, and temporarily expanding the boundary zone adjacent to the edge of the touch sensor if the at least one pointing object is moving rapidly to thereby compensate for the rapid movement that might otherwise not be recognized as an edge swipe gesture.
