Abstract

A display apparatus includes: a display unit; a user interface (UI) generator which generates UI information to be displayed on the display unit; a user input unit which includes a touch pad; and a controller which controls the UI generator to display a plurality of selective items per item page on the display unit, to move a focus in accordance with a touch motion of the user, and to stop moving the focus if the focus is located at an outermost selective item positioned at an edge of the item page.

Claims

1. A display apparatus comprising:

a display unit;

a user interface (UI) generator which generates UI information to be displayed on the display unit;

a user input unit which comprises a touch pad and receives a touch motion; and

a controller which controls the UI generator to display a plurality of item pages, at least one item page of the plurality of item pages comprising a plurality of selective items displayed on the display unit, to move a focus among the plurality of the selective items in accordance with the touch motion from the user input unit, and to stop moving the focus if the focus is located at an outermost selective item among the plurality of the selective items, the outermost selective item being positioned at an edge of the one item page of the plurality of item pages.

2. The display apparatus according to claim 1, wherein the controller controls the focus to be movable if the touch motion is generated after the user stops contacting the touch pad while the focus is located at the outermost selective item.

3. The display apparatus according to claim 2, wherein the controller determines whether a first direction of the touch motion generated before the user stops contacting the touch pad is same as a second direction of the touch motion generated after the user stops contacting the touch pad and reestablishes contact with the touch pad, and controls the UI generator to move the plurality of item pages in the first or the second direction of the touch motion if it is determined that the first and the second directions are same.

4. The display apparatus according to claim 1, wherein the plurality of selective items are arranged in a latticed pattern.

5. The display apparatus according to claim 1, wherein the controller controls the UI generator to move the focus among the plurality of the selective items in accordance with a moving distance and a moving speed based on the touch motion of the user.

6. The display apparatus according to claim 1, wherein the user input unit remotely communicates with the controller.

7. A display apparatus comprising

a display unit;

a user interface (UI) generator which generates UI information to be displayed on the display unit;

a signal receiver which receives a touch motion signal as a user operates a touch pad; and

a controller which controls the UI generator to display a plurality of item pages, at least one item page of the plurality of item pages comprising a plurality of selective items displayed on the display unit, to move a focus among the plurality of selective items in accordance with the touch motion signal, and to stop moving the focus if the focus is located at an outermost selective item among the plurality of the selective items, the outermost selective item being positioned at an edge of the one item page of the plurality of item pages.

8. The display apparatus according to claim 7, wherein the touch motion signal comprises a signal indicating whether the user is contacting the touch pad, and

the controller controls the focus to be movable if, while the focus is located at the outermost selective item, the signal receiver receives a signal indicating that the user is contacting the touch pad after receiving a signal indicating that the user is not contacting the touch pad.

9. The display apparatus according to claim 8, wherein the touch motion signal is based on a direction of a touch motion of the user, and the controller determines whether a first direction of the touch motion generated before the user stops contacting the touch pad is same as a second direction of the touch motion generated after the user stops contacting the touch pad and reestablishes contact with the touch pad, and controls the UI generator to move the plurality of the item pages in the first or the second direction of the touch motion if it is determined that the first and the second directions of the touch motions are same.

10. The display apparatus according to claim 9, wherein the controller controls the UI generator to move the focus in accordance with a moving distance and a moving speed based on the touch motion of the user.

11. The display apparatus according to claim 7, wherein the plurality of selective items are arranged in a latticed pattern.

12. A method of controlling a display apparatus that displays a plurality of item pages, at least one item page of the plurality of item pages comprising a plurality of selective items, the method comprising:

determining whether a focus moving among the plurality of the selective items in accordance with a touch motion of a user is located at an outermost selective item among the plurality of the selective items, the outermost selective item being positioned at an edge of the one item page of the plurality of item pages; and

stopping moving the focus if it is determined that the focus is located at the outermost selective item.

13. The method according to claim 12, further comprising moving the focus if the user inputs a touch motion on a touch panel after the user stops contacting the touch panel.

14. The method according to claim 13, further comprising

determining whether a first direction of the touch motion generated before the user stops contacting the touch panel is same as a second direction of the touch motion generated after the user stops contacting the touch panel and reestablishes contact with the touch panel;

and

moving the plurality of the item pages in the first or the second direction of the touch motion if it is determined that the first and the second directions of the touch motion are same.

15. A display apparatus comprising:

a display unit;

a user interface (UI) generator which generates UI information to be displayed on the display unit;

a user input unit which receives a user input motion of a user; and

a controller which controls the UI generator to display a plurality of scrollable pages, wherein at least one of the plurality of scrollable pages comprises a plurality of selective items, moves a focus among the plurality of the selective items in accordance with the user input motion of the user, and stops moving the focus if the focus is located at an outermost selective item among the plurality of selective items on one of the plurality of scrollable pages.

16. The display apparatus according to claim 15, wherein the controller moves the focus after stopping the focus if the user input motion of the user is input, the user input motion is then stopped, and the user input motion is then input.

17. The display apparatus according to claim 16, wherein the controller determines whether a first direction of the user input motion before being stopped is same as a second direction of the user input motion after being stopped, and if the first and the second directions of the user input motion are same, scrolls the scrollable page that is displayed on the display unit among the plurality of the scrollable pages in the first or the second direction of the user input motion.

18. The display apparatus according to claim 15, wherein the user input unit comprises a touch panel.

19. A method of controlling a display apparatus that displays a plurality of scrollable pages, wherein at least one scrollable page of the plurality of scrollable pages comprises a plurality of selective items, the method comprising:

moving a focus among the plurality of selective items in accordance with a user input motion of a user;

determining whether the focus is located at an outermost selective item among the plurality of the selective items on one of the plurality of scrollable pages; and

stopping moving the focus if it is determined that the focus is located at the outermost selective item of one of the plurality of scrollable pages.

20. The method according to claim 19, further comprising moving the focus among the plurality of selective items after stopping moving the focus if a user input motion of the user is input, the user input motion is then stopped, and the user input motion is then input.

21. The method according to claim 20, further comprising determining whether a first direction of the user input motion before being stopped is same as a second direction of the user input motion after being stopped, and if the first and the second directions of the user input motion are same, scrolling the plurality of scrollable pages in the first or the second direction of the user input motion.
