Abstract

A device and method for displaying a list in a portable terminal having a touch pad are provided. The portable terminal includes an input unit for generating a sweep event; a speed-determining unit for checking speed of the sweep event and setting a scroll speed corresponding to the speed of the sweep event; a controller for controlling scrolling through items on a list according to the scroll speed; and a display for displaying the scrolled items on the list under the control of the controller. Therefore, the list scroll can be easily performed according to the inputted sweep event.

Claims

1. A portable terminal comprising:

an input unit having a touch pad, for generating a sweep event of the touch pad;

a speed-determining unit for checking a speed of the sweep event and setting a scroll speed corresponding to the speed of the sweep event;

a controller for controlling a scrolling through of items on a list according to the scroll speed; and

a display for displaying the scrolled items on the list under the control of the controller.

2. The portable terminal of claim 1, wherein the controller stops the scrolling through of the items when a preset time elapses.

3. The portable terminal of claim 1, wherein:

the touch pad comprises two or more sensors; and

the sweep event is generated when at least two sensors output touch signals in a contact state.

4. The portable terminal of claim 3, wherein the speed-determining unit checks a direction of the sweep event and sets a scroll direction in response to the direction of the sweep event.

5. The portable terminal of claim 4, wherein the scroll speed is a constant speed.

6. The portable terminal of claim 4, wherein the scroll speed is accelerated to a certain speed and then decelerated.

7. The portable terminal of claim 1, wherein the controller stops the scrolling through of the items when a touch signal is detected while scrolling through the items on the list.

8. The portable terminal of claim 1, wherein the display highlights a specific item on the list.

9. A method for scrolling through a list of a portable terminal comprising:

checking whether a sweep event occurs in a touch pad;

checking a speed of the sweep event and setting a scroll speed in response to the speed of the sweep event; and

scrolling through items on the list in response to the scroll speed.

10. The method of claim 9, further comprising:

stopping the scrolling through of the items when a preset time elapses, while scrolling through the list.

11. The method of claim 9, wherein:

the touch pad comprises two or more sensors; and

the sweep event is generated when at least two sensors output touch signals in a contacting state.

12. The method of claim 11, wherein the setting the speed of the sweep event comprises:

checking a direction of the sweep event; and

setting a scroll direction in response to the direction of the sweep event.

13. The method of claim 12, wherein the scroll speed is a constant speed.

14. The method of claim 12, wherein the scroll speed is accelerated to a certain speed and then decelerated.

15. The method of claim 9, wherein the scrolling through of the items on the list is stopped when a touch signal is detected.

16. The method of claim 9, wherein the scrolling through of the items on the list comprises highlighting a specific item on the items on the list.
