Abstract:
The method and device for capacitive position detection are disclosed. The touch related sensors within a sensing device with a plurality of sensors are detected first. Therefore at least a range of the mutual capacitance detection for detecting sensing information can be determined according to the touch related sensors. The sensing information within the range of the mutual capacitance detection can be used for generating a two-dimension sensing information.
