Abstract: A touch sensing system including a touch input interface and a capacitance sensing circuit is provided. The touch input interface includes a plurality of sensing capacitors for outputting a capacitance under test and a reference capacitance. The capacitance sensing circuit includes a first sensing channel, a second sensing channel, and a difference comparing unit. During a first period of the sensing period, the first sensing channel senses the capacitance under test, and the second sensing channel senses the reference capacitance. During a second period of the sensing period, the first sensing channel senses the reference capacitance, and the second sensing channel senses the capacitance under test. The difference comparing unit outputs a difference according to the capacitance under test and the reference capacitance. Additionally, a capacitance sensing method is also provided.

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.
