Abstract
The present invention relates to a scrolling method in a mobile terminal. When a user drags a touch point drawing a circular trajectory on a screen, a scroll direction and a scroll speed are determined based on the dragging direction and the size of the circular trajectory, respectively. Therefore, according to the present invention, precise and intuitive scrolling control is enabled even when a multimedia file having a long playback time or a list having a lot of items is processed in spite of the small screen size of the mobile terminal.
