FIG. 4 is a flowchart illustrating a method of providing contents according to a mode in a multi-touch post-drag input according to an embodiment of the present invention.

Referring to FIG. 4, when a mode such as a menu mode, an execution mode, and the like is selected through a user input or the like (S410), the controller 180 displays a screen corresponding to the selected mode (S415). When the selected mode is the menu mode, the controller 180 lists and displays a plurality of items related to the functions or contents of the portable terminal, and when the selected mode is the execution mode, Indicate some.

On the other hand, the controller 180 determines whether multi-touch has been received (S420). The user can touch the touch screen using at least two touch pointers (e.g., fingers). Then, the touch point is generated on the touch screen on which the touch pointer is touched, so that the controller 180 determines that the multi touch is received.

If the mode when the multitouch is received is the menu mode (S420-Y, S425-Y), the control unit 180 displays the additional information of the content corresponding to the item displayed in the area where the multitouch is received (S430) . Here, the additional information is information for explaining the functions, characteristics, and the like of the content, such as a preview screen or a pop-up window explaining the function.

If the mode when the multitouch is received is the first execution mode of the execution mode (S440-Y), the controller 180 changes the playback speed of the executed content in accordance with the direction of multi-touch and dragging (S445) . Then, the content is displayed at the changed playback speed (S450).

If the mode when the multi-touch is received is the second execution mode of the execution mode (S460-Y), the control unit 180 terminates the execution of the executed content corresponding to the direction of multi-touch and dragging, Related content (hereinafter referred to as " related content ") and displays it (S465).

As described above, since the multi-touch post-drag user command is recognized as another command according to the mode and operated, the user can input various commands in various modes by one command.

5 is a flowchart illustrating a content display method according to a user command for dragging and then dragging in multi-touch in a first execution mode according to an embodiment of the present invention.

The control unit 180 reproduces a part of the content corresponding to the first execution mode and displays it on the touch screen (S510). The first execution mode is a mode in which a portion of the content is reproduced and the rest of the content is sequentially reproduced at a constant playback speed in accordance with time even if no separate user command is received. .

If it is determined that a user command to drag the touch point in the direction of approaching each other is received (S530-Y), the controller 180 decreases the playback speed in response to the dragged distance (540). Specifically, whenever the dragged distance increases by a unit distance, the controller 180 preferably decreases the playback speed by a unit speed. Then, the content is reproduced at a reduced playback speed and displayed on the touch screen (S550).

On the other hand, if it is determined that the user command to drag the touch pointer in the direction away from the touch point after the multi-touch is received (S560-Y), the controller 180 increases the playback speed in accordance with the dragged distance (S570). That is, the controller 180 preferably increases the playback speed by a unit speed each time the dragged distance increases by a unit distance. Then, the content is reproduced and displayed at an increased reproduction speed (580).
