Abstract

A mobile terminal having a circle type display and a method for controlling the same is disclosed herein. A scroll bar is provided at an edge of the circle type display in response to a user input. The user may control the mobile terminal and the circle type display through touch inputs on the scroll bar.

Claims

1. A method for displaying data in a user device to be wearable on wrist of a user having a circle type display, the method comprising:

detecting a user input;

generating a scroll bar at an edge of the circle type display in response to the detected user input;

detecting a first touch input on the scroll bar, wherein the first touch input is a touch-and drag input on the scroll bar; and

performing a first change to a data displayed on the circle type display in response to the detected first touch input.

2. The method of claim 1, further comprising

detecting a second touch input on the scroll bar, wherein the second touch input is a touch-and-drag input on the scroll bar, and

performing a second change to the data displayed on the circle type display in response to the detected second touch input.

3. The method of claim 2, further comprising changing a color of the scroll bar in response to the second touch input.

4. The method of claim 2, wherein the performing the first change includes scrolling the data displayed on the circle type display, and the performing the second change includes a zoom-in or zoom-out of the data displayed on the circle type display.

5. The method of claim 2, further comprising

detecting a third touch input on the scroll bar, wherein the third touch input comprises a simultaneous touch input at two separate locations on the scroll bar, and

performing a third change to the data displayed on the circle type display unit in response to the third touch input.

6. The method of claim 5, wherein the performing the first change includes scrolling the data displayed on the circle type display, and the performing the second change includes a zoom-in or zoom-out of the data displayed on the circle type display, and the performing the third change includes moving the data displayed on the circle type display.

7. The method of claim 1, further comprising displaying a menu list on the circle type display unit, wherein the scroll bar comprises a title scroll bar and a menu scroll bar.

8. The method of claim 1, further comprising

displaying a menu list on the circle type display unit, and

displaying an index of the menu list on the scroll bar.

9. The method of claim 1, further comprising

displaying a plurality of menu items on the scroll bar,

detecting a touch-and-drag input on at least one of the plurality of menu items, and

replacing each of the plurality of menu items except the touched menu item with a sub-menu item associated with the touched menu item.

10. The method of claim 1, further comprising

displaying a control menu on the circle type display;

and

detecting a third touch input on the scroll bar, wherein the third touch input comprises a simultaneous touch input at the control menu and the scroll bar, and

performing a third change to the data displayed on the circle type display unit in response to the third touch input.

11. A display device for a wrist watch, comprising:

a circle type display configured to display data; and

a controller configured to display a scroll bar at an edge of the circle type display in response to a user input and to change the displayed data on the circle type display in response to a first touch input on the scroll bar, wherein the first touch input is a touch-and-drag input on the scroll bar.

12. The display device of claim 11, wherein the controller controls the circle type display to change the data displayed on the circle type display in response to a second touch input, wherein the second touch input is a touch hold-and-drag on the scroll bar.

13. The display device of claim 12, wherein the controller controls the circle display unit such that a color of the scroll bar is changed in response to the second touch input.

14. The display device of claim 12, wherein the change in response to a first touch input scrolls the data displayed on the circle type display, and the change in response to the second touch input includes a zoom-in or zoom-out of the data displayed on the circle type display.

15. The display device of claim 12, wherein the controller controls the circle type display to change the data displayed on the circle type display in response to a third touch input, wherein the third touch input is a simultaneous touch input at two separate locations on the scroll bar.

16. The display device of claim 15, wherein the change in response to the first touch input scrolls the data displayed on the circle type display, the change in response to the second touch input includes a zoom-in and zoom-out of the data displayed on the circle type display, and the change in response to the third touch input moves the data displayed on the circle type display.

17. The display device of claim 11, wherein the data is a menu list, and the scroll bar comprises a title scroll bar and a menu scroll bar.

18. The display device of claim 11, wherein the data is a menu list and the controller controls the circle type display unit to display the scroll bar with an index of the menu list.

19. The display device of claim 11, wherein a plurality of menu items are displayed on the scroll bar, and wherein

in response to a touch-and-drag input on at least one of the plurality of menu items, the controller is configured to replace each of the plurality of menu items except the touched menu item with a sub-menu item associated with the touched menu item.

20. The display device of claim 11, wherein the circle type display is configured to display a control menu associated with the data, and wherein the controller is configured to change the data displayed in response to a third touch input on the scroll bar, wherein the third touch input comprises a simultaneous touch input at the control menu and the scroll bar.
