Abstract

A method and apparatus for controlling a drag to variably change the speed of an object moving on a display unit includes displaying an object and a control region for controlling a movement of the object, wherein if a touch input is detected from the control region, the control unit determines whether duration of a drag input after the initial touch input is longer than a predetermined time period, then the control unit defines a ratio of a drag speed and an object speed, based on the determination outcome so that the object is moved in response to the drag input according to the defined ratio.

Description

technical field [0001] The present invention generally relates to a method and apparatus for controlling dragging of an object for moving a mobile terminal having a touch screen. Background technique [0002] In recent years, mobile terminals have developed into multimedia devices that can provide various types of additional services such as electronic note function, game function, schedule management function, etc., for example. There is a need for a user interface that allows users to easily use and manage such services. [0003] Generally, when an object such as a cursor or a picture is moved by a dragging motion, a dragging speed and an object speed are set to be equal. In this case, the actual movement of the drag corresponds to the object's velocity in a 1:1 ratio. However, finely moving the cursor is difficult when it is necessary to move the cursor in sentences with small fonts and narrow spacing. [0004] Accordingly, there is a need to address the above-mentione...
