Abstract
A method for inputting text in a mobile terminal having a touch screen is provided. When detecting a touch-down, the mobile terminal displays a character of the touch-down point and nearby characters in an enlarged size and indicates the character of the touch-down point in the enlarged display. When a drag event occurs before a touch-up event, the mobile terminal determines the dragging distance and direction, changes the touch-down point to a new location according to the dragging distance and direction, and indicates another character at the new location. When a touch-up event occurs at the new location, the mobile terminal then inputs the other character indicated at the new location.
