Abstract: Provided herein are a pin sharing circuit, a pin sharing method and an electronic device, an electronic wire using the same. The pin sharing circuit enables at least one pin on an integrated circuit to be shared by a keyboard device and a touch panel and prevents signal interference between the keyboard device and the touch panel using an impedance element disposed on a wire for the pin, such that the pin can output or receive a stimulation signal and a sensor signal that contain both an AC component and a DC component so as to enhance the efficiency of the overall system and prevent the stimulation signal and the sensor signal from conflicts between the keyboard device and the touch panel.

Abstract: Disclosed is a three-dimensional gesture sensing method. The three-dimensional gesture sensing method comprises the following steps. Step A: driving at least one first conductive line of conductive lines in the touch sensing device as a first working sensing line, and driving at least one second conductive line of the conductive lines in the touch sensing device as a second working sensing line, such that a sensing area is formed between the first working sensing line and the second working sensing line. Step B: detecting a conductor according to the sensing area. Step C: dynamically adjusting at least the area, the position or the amount of the sensing area according to the conductor to implement a three-dimensional gesture sensing.
