Abstract: A single-finger and multi-touch gesture determination method is disclosed. The single touch and multi-touch gesture determination method includes steps of: for each of one or more touch points, judging a respective category under a first group to which the touch point belongs, according to an initial position of the touch point; for each of the one or more touch points, judging a respective category under a second group to which the touch point belongs, according to a moving pattern of the touch point, wherein the moving pattern is respectively defined in the judged category under the first group to which the touch point belongs; and determining a gesture represented by the one or more touch points according to the judged categories under the second group respectively to which the one or more touch points belong.

Abstract: A single finger gesture determination method is disclosed. The single touch gesture determination method includes steps of detecting one or more trigger signals, determining respective categories under a plurality of gesture groups to which the one or more trigger signals belong according to the one or more trigger signals, and deciding a finger gesture represented by the one or more trigger signals according to the determined respective categories under the plurality of gesture groups.

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.

Abstract: A touch sensing system includes a touch interface and a control unit. The touch interface senses at least one area change generated on the touch interface by at least one object.
