The present invention relates to a method and a device for recognizing a touch input, wherein any contact or approach of a touch means (90) such as a human finger, conductor or touch pen with or to a touch panel (10) is detected to generate an input signal. The method for recognizing a touch input according to the present invention comprises: (a) detecting a 1st touch input; (b) calculating an area of the region where the 1st touch input is detected; (c) detecting a 2nd touch input that occurs after a predetermined time interval from the 1st touch input; (d) calculating an area of the region where the 2nd touch input is detected; and (e) determining a change in the areas of the 1st and 2nd touch inputs to generate a zooming signal. According to the method, as a zooming signal is generated by a change in the touch input area, a zoom gesture can be implemented in a very simple way using only one finger, thereby simplifying the touch input operation. |
