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 for a predetermined amount of time on the circle type display;

displaying a first scroll bar at an edge of the circle type display in response to the user input, the first scroll bar being displayed on the circle type display at a first region along a circumference of the display or displaying a second scroll bar at an edge of the circle type display in response to the user input, the second scroll bar being displayed on the circle type display at a second region along the circumference of the display;

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

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

wherein the first region is provided at a lower portion of the display and the second region is provided at an upper portion of the display, and

wherein the first and second scroll bars extend partially along the circumference of the display, an arc length of the first scroll bar being greater than an arc length of the second scroll bar.

2. The method of claim 1, further comprising

detecting a second type of touch input on the first scroll bar, wherein the second type of touch input is a touch-hold-and-drag input on the first scroll bar, and

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

3. The method of claim 2, further comprising changing a color of the scroll bar in response to the second type of 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 type of touch input on the first scroll bar, wherein the third type of touch input comprises a simultaneous touch input at two separate locations on the first in scroll bar, and

performing a third change to the data displayed on the circle type display response to the third type of 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, wherein the second scroll bar is a title scroll bar to change to another menu and the first scroll bar is a menu scroll bar to scroll the menu list.

8. The method of claim 1, further comprising

displaying a menu list on the circle type display, and

displaying an index of the menu list on the first or second scroll bar.

9. The method of claim 1, further comprising

displaying a plurality of menu items on a third 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 type of touch input on the first scroll bar, wherein the third type of touch input comprises a simultaneous touch input at the control menu and the first scroll bar, and

performing a third change to the data displayed on the circle type display in response to the third type of 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 title for a menu,

display a first scroll bar or a second scroll bar at an edge of the circle type display in response to a user input for a predetermined amount of time on the circle type display, the first or second scroll bar being displayed on the circle type display, and

change the displayed data on the circle type display in response to a first type of touch input on the first or second scroll bar, wherein the first type of touch input is a touch-and-drag input on the scroll bar,

wherein the first scroll bar extends under the title and the second scroll bar extends over the title, and

wherein lengths of the first and second scroll bars are less than a circumference of the display, the length of the first scroll bar being greater than the length of the second 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 type of touch input, wherein the second type of touch input is a touch-hold-and-drag on the type of scroll bar.

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

14. The display device of claim 12, wherein the change in response to the first type of touch input scrolls the data displayed on the circle type display, and the change in response to the second type of 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 type of touch input, wherein the third type of touch input is a simultaneous touch input at two separate locations on the first scroll bar.

16. The display device of claim 15, wherein the change in response to the first type of touch input scrolls the data displayed on the circle type display, the change in response to the second type of 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 type of 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 second scroll bar is a title scroll bar to change between a plurality of menus and the first scroll bar is a menu scroll bar to scroll the menu list.

18. The display device of claim 11, wherein the data is a menu list and the controller controls the circle type display to display the first or second 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 a third 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 control output of a multimedia data in response to a simultaneous touch input at the control menu and the first scroll bar.

21. The method of claim 11, wherein the first type of touch input at the first scroll bar scrolls contents of the menu and the first type of touch input at the second scroll bar changes the menu.
