Abstract

An image display device includes a display configured to display a plurality of items and a cursor indicating a location of an input; input receiving circuitry configured to receive an input for moving the cursor; and a controller configured to control the cursor to move in accordance with the received input, to control items adjacent to the cursor to be set as candidate items if the cursor stops moving, and to control guidelines to be displayed on the candidate items, wherein in response to an input of a direction key while the focus is displayed on the first candidate item, and wherein the controller is further configured to control the focus to move to a second candidate item among the candidate items corresponding to the input of the direction key if the input of the direction key corresponds to a short press and to control the cursor to move in a direction corresponding to the input of the direction key if the input of the direction key corresponds to a long press.

First claim

What is claimed is:

1. An image display device comprising:
a display configured to display a plurality of items and a cursor indicating a pointing position determined by a received input;
a controller configured to control the cursor to move in response to input of a direction key, to control the cursor to remove if the cursor stops moving, and to control to display a focus on a first candidate item among candidate items adjacent to the cursor,
wherein the controller is further configured to control the focus to move to a second candidate item among the candidate items, in response to another input of a direction key while the focus is displayed on the first candidate item.

2. The image display device of claim 1 , wherein the input for moving the cursor is a long press of the direction key, and
wherein the controller is configured to control a moving speed of the cursor to be increased based on receiving the long press of the direction key.

3. The image display device of claim 1 , wherein the controller is configured to set the candidate items based on a path in which the cursor moves.

4. The image display device of claim 3 , wherein the controller is configured to control items adjacent to the cursor in a same direction as a direction in which the cursor moves, and in a different direction from a direction in which the cursor moves to be set as the candidate items.

5. The image display device of claim 1 , wherein the controller is configured to control to display guidelines on the candidate items.

6. The image display device of claim 5 , wherein, the controller is configured to control the focus to be located on a candidate item on which the cursor is located and to control the cursor to stop being displayed if the guidelines are displayed on the candidate items.

7. The image display device of claim 6 , wherein the controller is configured to highlight the candidate item on which the focus is located.

8. The image display device of claim 1 , wherein in response to a long press of the direction key, the controller is configured to control the cursor to move in a direction corresponding to the pressed direction key, and in response to a key release following the long press of the direction key, the controller is configured to stop the displaying the cursor and to display the focus.

9. The image display device of claim 1 , wherein the controller is configured to control to stop the focus from being displayed when another input of the direction key is not sensed for a predetermined time period while the focus is displayed.

10. The image display device of claim 1 , wherein in response to another input of the direction key while the focus is displayed on the second candidate item, the controller is configured to control to stop the focus from being displayed, when there is no candidate item in the direction corresponding to another input of the direction key with respect to the second candidate item.

11. A method of operating an image display device, the method comprising:
displaying, on a display, a plurality of items and a cursor indicating a pointing position determined by a user input;
receiving the user input of a direction key;
moving the cursor in response to the user input of the direction key, removing the cursor if the cursor stops moving, and displaying a focus on a first candidate item among candidate items adjacent to the cursor; and
in response to another input of a direction key while the focus is displayed on the first candidate item, moving the focus to a second candidate among the candidate items.

12. The method of claim 11 , wherein the input for moving the cursor is a long press of the direction key, and if the long press of the direction key is received, a moving speed of the cursor is set to be increased.

13. The method of claim 11 , wherein the candidate items are set based on a path in which the cursor moves.

14. The method of claim 13 , wherein the candidate items comprise items adjacent to the cursor in a same direction as a direction in which the cursor moves and in a different direction from a direction in which the cursor moves.

15. The method of claim 11 , further comprising: displaying the guidelines on the candidate items.

16. The method of claim 15 , further comprising: locating the focus on a candidate item on which the cursor is located and not displaying the cursor if the guidelines are displayed on the candidate items.

17. The method of claim 16 , further comprising: highlighting the candidate item on which the focus is located.

18. The method of claim 11 , wherein moving the cursor in the direction comprises, in response to a long press of the direction key, moving the cursor in a direction corresponding to the pressed direction key, and
further comprising: in response to a key release following the long press of the direction key, stopping display of the cursor and displaying the focus.

19. The method of claim 11 , further comprising: removing the focus when the input of the direction key is not sensed for a predetermined time period while the focus is displayed.
