Abstract

A scrolling method, which includes displaying at least one scroll icon on a screen of a touch device, sensing an operation in which one of the displayed scroll icons is touched and dragged, and scrolling the screen displayed on the touch device in a direction in which the touched scroll icon is dragged when the sensing step senses the scroll icon is touched and dragged.

Claims

1. A scrolling method, comprising:

displaying at least one scroll icon on a screen of a touch device;

sensing an operation in which one of the at least one displayed scroll icon is touched and dragged; and

scrolling the screen displayed on the touch device in a direction in which the touched scroll icon is dragged when the sensing step senses the scroll icon is touched and dragged.

2. The scrolling method as claimed in claim 1, further comprising:

returning the touched and dragged scroll icon to its original position after the scrolling step has finished.

3. The scrolling method as claimed in claim 1, wherein the displaying step displays the at least one scroll icon as a transparent scroll icon.

4. The scrolling method as claimed in claim 1, wherein the at least one scroll icon includes an upward and downward scroll icon, and

wherein the displaying step displays the upward and downward scroll icons on upper and lower sides of the touch device, respectively.

5. The scrolling method as claimed in claim 1, wherein the at least one scroll icon includes an upward and downward scroll icon, and

wherein the displaying step displays the upward and downward scroll icons on upper and lower sides and in a diagonal manner, respectively, on the touch device such that the upper and downward scroll icons are diagonally across from each other.

6. The scrolling method as claimed in claim 1, further comprising:

storing a scroll unit corresponding to an amount of the displayed screen to be scrolled,

wherein the scrolling step scrolls the screen displayed on the touch device according to the stored scroll unit.

7. The scrolling method as claimed in claim 6, wherein the scroll unit is a line or page unit indicating the displayed screen is to be scrolled on a line by line basis or a page by page basis, respectively.

8. The scrolling method as claimed in claim 6, wherein the scroll unit is arbitrarily set by a user.

9. The scrolling method as claimed in claim 1, wherein the touch device comprises an electrostatic touch device.

10. A mobile communication terminal, comprising:

a touch screen display configured to be touched by a user to input information into the terminal and; and

a controller configured to display at least one scroll icon on the touch screen, to sense an operation in which the at least one displayed scroll icon is touched and dragged, and to scroll information displayed on the touch screen in a direction in which the touched scroll icon is dragged.

11. The mobile communication terminal as claimed in claim 10, wherein the controller returns the touched and dragged scroll icon to its original position after the information is scrolled.

12. The mobile communication terminal as claimed in claim 10, wherein the controller displays the at least one scroll icon as a transparent scroll icon.

13. The mobile communication terminal as claimed in claim 10, wherein the at least one scroll icon includes an upward and downward scroll icon, and

wherein the controller displays the upward and downward scroll icons on upper and lower sides of the touch screen display, respectively.

14. The mobile communication terminal as claimed in claim 10, wherein the at least one scroll icon includes an upward and downward scroll icon, and

wherein the controller displays the upward and downward scroll icons on upper and lower sides and in a diagonal manner, respectively, on the touch screen display such that the upper and downward scroll icons are diagonally across from each other.

15. The mobile communication terminal as claimed in claim 10, further comprising:

a memory unit configured to store a scroll unit corresponding to an amount of the displayed screen to be scrolled,

wherein the controller scrolls the information displayed on the touch device according to the stored scroll unit.

16. The mobile communication terminal as claimed in claim 15, wherein the scroll unit is a line or page unit indicating the displayed information is to be scrolled on a line-by-line basis or a page-by-page basis, respectively.

17. The mobile communication terminal as claimed in claim 15, wherein the scroll unit is arbitrarily set by a user.

18. The mobile communication terminal as claimed in claim 10, wherein the touch device comprises an electrostatic touch device.

19. A method of communicating on a mobile communication terminal, the method comprising:

displaying a list of contact names on a display of the mobile communication terminal, each contact name corresponding to a telephone number of the contact name such that when the contact name is selected, the telephone number corresponding to the contact name is displayed;

displaying at least two scroll indicators on a right side of the list of contact names; and

moving to a predetermined position in the list of contact names in correspondence with a touching and dragging operation of the at least two scroll indicators.

20. A mobile communication terminal, comprising:

a touch screen display configured to display a list of contact names, each contact name corresponding to a telephone number of the contact name such that when the contact name is selected, the telephone number corresponding to the contact name is displayed; and

a controller configured to display at least two scroll indicators on a right side of the displayed list of contact names, and to move to a predetermined position in the list of contact names in correspondence with a touching and dragging operation of the at least two scroll indicators.
