Abstract: The present invention relates to a touchscreen input method. The objective of the present invention is to implement a touch interface using intuitive vision through simple use of a pop-up menu and an accurate pointing function and selection using a cursor on a screen. The present invention may comprise the steps of: sensing a first touch on a first point and a second touch on a second point which simultaneously occur on the touch screen; displaying a cursor in a location between the first point and the second point; displaying the cursor while moving the cursor when both the first touch and the second touch move without disappearing from the touchscreen; and performing a predetermined operation if, after the touch screen has been touched by the first touch and the second touch, the first touch disappears and then again occurs on the touchscreen.
