1. A capacitive sensing method, comprising:

  • sensing signals or signal changes of a plurality of intersecting points on a touch panel through mutual capacitance of the touch panel, wherein the touch panel includes intersecting points formed from a plurality of perpendicular conductive lines and a plurality of electrical conductors respectively crossing or surrounding the intersecting points, wherein a predetermined range is determined based on the electrical conductors;

    identifying the location of an object touching or getting near the touch panel based on the signals or signal changes of the intersecting points that fall within the predetermined range; and

    continuously identifying the locations of the object to determine whether it is a command gesture.
