Touch sensing method and system using the same

Abstract

A touch sensing system including a touch interface and a control unit is provided. The touch interface senses at least one edge change of at least one region on the touch interface corresponding to at least one object. The control unit defines a touch gesture corresponding to the object according to the edge change so as to perform a touch operation corresponding to the touch gesture. Additionally, a touch sensing method is also provided. In the touch sensing method, whether the touch gesture is a moving gesture, a rotation gesture, a flip gesture, a zoom-in gesture, or a zoom-out gesture is determined according to any change of a touch region.

Dependencies are inferred from the claim text.
