  • a sensor to sense an object contacting a specific position corresponding to one among a plurality of sensing channels arranged in a predetermined array;

    a detector to detect at least one of information about signal strength of the sensing channel in which the object is sensed and information about the number of sensing channels having a signal strength exceeding a first threshold; and

    a controller to determine whether a single touch or a multi touch has been sensed based on the detected information,wherein when the number of sensing channels having the signal strength exceeding the first threshold is greater than a second threshold, the controller determines that a multi touch has been sensed.
