<p>PURPOSE: A touch input method for recognizing for simplifying the touch input of user is provided to realize the zoom gesture with simple operation by creating zoom in or zoom out signal according to the increase and decrease of the size of the second touch input area. CONSTITUTION: A first touch input is detected(ST100). The area of the first touch input detection area is calculated(ST110). The second touch input is detected(ST120). The second touch input is created after the first touch input in the designated time interval. The area of the second touch input detection area is calculated(ST130). The change is determined between the area about the area about the first touch input and the second touch input(ST140). If the area about the second touch input is bigger than the area about the first touch input, the zoom in signal is generated(ST150). If the area about the second touch input is not bigger than the area about the first touch input t is not, the zoom out signal is generated(ST160).</p> |
