Abstract
Touch sensor methods, devices and systems are disclosed. One embodiment of the present invention pertains to a method comprising monitoring a finger movement along a touch sensing surface based on position data of a finger touching the touch sensing surface, where the position data is obtained by locating a position of a force applied by the finger in a coordinate of the touch sensing surface. In addition, the method comprises generating direction data associated with the finger movement if the finger movement travels for more than a threshold distance. Furthermore, the method comprises determining a finger gesture which corresponds to the finger movement using a lookup table having multiple preconfigured finger gestures based on the direction data.
