Abstract

The present invention relates to an electronic device and a method of controlling the same. The present invention provides a new user interface for selecting, executing and controlling an item displayed on a touch screen included in the electronic device. Particularly, the present invention provides an electronic device and a method of controlling the same to manipulate the touch screen included in the electronic device while hardly changing the positions of the hands of a user when the touch screen is manipulated with both hands of the user.

Claims

1. An electronic device, comprising:

a touch screen configured to display a first item group that includes a first plurality of items; and

a controller configured to control the touch screen to provide a first control area and a second control area, the first control area to display a first plurality of colors, each color corresponding to a different one of the first plurality of items, the second control area for executing an item of the first plurality of items displayed on the touch screen, wherein in response to a touch received at the first control area, the controller to navigate among the first plurality of items displayed on the touch screen based on a relationship between the first plurality of items and the first plurality of colors, and in response to a touch at the second control area, the controller to execute a specific item of the first plurality of items.

2. The electronic device of claim 1, wherein the controller activates the first control area and the second control area in response to the electronic device receiving a first command, and the controller to deactivate the first control area and the second control area in response to the electronic device re-receiving the first command or receiving a second command that is different from the first command.

3. The electronic device of claim 1, wherein the controller displays the first plurality of colors such that the colors are visually distinguished from each other.

4. The electronic device of claim 3, wherein in response to receiving a touch to a specific color of the first plurality of colors, the controller selects an item corresponding to the touched specific color and visually emphasizes the selected item.

5. The electronic device of claim 4, wherein the controller displays a visual indicator with regard to the selected item.

6. The electronic device of claim 4, wherein the controller displays the second control area as a plurality of sub-areas, sets a first sub-area of the plurality of sub-areas as a touch area for executing the selected item, and allocates at least one function to a second sub-area of the plurality of sub-areas.

7. The electronic device of claim 6, wherein in response to receiving a touch at the second control area, the controller displays a screen for executing the selected item, the controller displays, on the screen, a second item group that is different from the first item group, the controller controls the first control area to display a second plurality of colors, each corresponding to a separate one of a second plurality of items, and in response to a touch at the first control area, the controller navigates among the second plurality of items based on a relationship between the second plurality of items and the second plurality of colors.

8. The electronic device of claim 7, wherein the controller maintains functions allocated to the sub-areas of the second control area when the screen for executing the selected item is displayed.

9. The electronic device of claim 7, wherein the controller allocates at least one new function to at least one sub-area of the second control area when the screen for executing the selected item is displayed.

10. A method of controlling a mobile terminal that includes a touch screen, the method comprising:

displaying, on the touch screen, a first item group that includes a first plurality of items;

providing a first control area and a second control area on the touch screen, the first control area displaying a first plurality of colors, each color corresponding to a different one of the first plurality of items, the second control area for executing an item of the first plurality of items displayed on the touch screen;

navigating among the first plurality of items displayed on the touch screen based on a relationship between the first plurality of items and the first plurality of colors in response to a touch received at the first control area; and

executing a specific item of the first plurality of items in response to a touch received at the second control area.

11. The method of claim 10, wherein providing the first control area and the second control area is performed in response to the electronic device receiving a first command, and the method further comprises deactivating the first control area and the second control in response to the electronic device re-receiving the first command or receiving a second command that is different from the first command.

12. The method of claim 10, wherein providing the first control area and the second control area comprises displaying the first plurality of colors in the first control area such that the colors are visually distinguished from each other.

13. The method of claim 12, further comprising in response to receiving a touch to a specific color, selecting an item corresponding to the touched specific color and visually emphasizing the selected item.

14. The method of claim 13, further comprising displaying a visual indicator with regard to the selected item.

15. The method of claim 13, further comprising displaying the second control area as a plurality of sub-areas, setting a first sub-area of the plurality of sub-areas as a touch area for executing the selected item, and allocating at least one function to a second one of the plurality of sub-areas.

16. The method of claim 15, further comprising in response to receiving a touch at the second control area, displaying a screen for executing the selected item, displaying, on the screen, a second item group that is different from the first item group, and displaying a second plurality of colors respectively corresponding to a second plurality of items included in the second item group;

and

navigating among the second plurality of items based on a relationship between the second plurality of items and the second plurality of colors in response to touches received at the first control area.

17. The method of claim 16, further comprising maintaining functions allocated to the sub-areas of the second control area when the screen for executing the selected item is displayed.

18. The method of claim 16, further comprising allocating a new function to at least one sub-area of the second control area when the screen for executing the selected item is displayed.

19. An electronic device comprising:

a screen to display a plurality of items, the screen to receive touch inputs; and

a controller to control the screen to display a first control area and a second control area, the first control area to include a plurality of different color indicators, wherein each color indicator of the first control area visually corresponds to a different one the plurality of items displayed on the screen, the second control area including a plurality of sub-areas, each corresponding to a different function, wherein the controller to select one of the plurality of items based on a touch input at the first control area, and the controller to perform a specific function based on a touch input at the second control area.

20. The electronic device of claim 19, wherein the controller controls the screen such that the plurality of different color indicators are visually distinguished from each other.

21. The electronic device of claim 19, wherein the controller controls the screen to provide a visual identifier with respect to a selected one of the items.
