Abstract

Disclosed is a display apparatus including: a display; an input comprising circuitry configured to receive a key moving command for moving between keys of an on-screen keyboard displayed on the display and a key-group selecting command for selecting a key group of the on-screen keyboard; and a processor configured to control a user interface (UI) of the on-screen keyboard, the keyboard comprising a first key group including keys=corresponding to a plurality of letters and a second key group including keys=corresponding to a plurality of functions, to be displayed on the display, to control an input marker moving between first keys of the first key group in response to the key moving command and at least one dummy marker moving between second keys of the first key group to be displayed if the first key group is selected by the key-group selecting command, to control an input of the first key to be made if a first key corresponding to the input marker is selected, to control a function marker moving between keys of the second key group in response to the key moving command to be displayed if the second key group is selected by the key-group selecting command, and to control a function of a key to be implemented if the key corresponding to the function marker is selected.

First claim

What is claimed is:

1. A display apparatus comprising:
a display;
an input comprising circuitry configured to receive a key moving command for moving between keys of an on-screen keyboard displayed on the display and a key-group selecting command for selecting a key group of the on-screen keyboard; and
a processor configured to control a user interface (UI) of the on-screen keyboard, the on-screen keyboard comprising a first key group including keys corresponding to a plurality of letters and a second key group including keys corresponding to a plurality of functions, to be displayed on the display, to control an input marker moving between first keys of the first key group in response to the key moving command and to control at least one dummy marker moving between second keys of the first key group to be displayed if the first key group is selected by the key-group selecting command, to control an input of the first key to be made if a first key corresponding to the input marker is selected corresponding, to control a function marker moving between keys of the second key group in response to the key moving command to be displayed if the second key group is selected by the key-group selecting command, and to control a function of a key to be implemented if the key corresponding to the function marker is selected.

2. The display apparatus according to claim 1 , wherein the input comprises a remote controller comprising a plurality of buttons.

3. The display apparatus according to claim 1 , wherein the processor is configured to control the function marker to be marked on a predetermined key of the second key group if the second key group is selected in response to the key-group selecting command.

4. The display apparatus according to claim 3 , wherein the predetermined key of the second key group corresponds to at least one of: a default key, a randomly selected key, a key just previously used and a key used more frequently than a predetermined number of times.

5. The display apparatus according to claim 3 , wherein the processor is configured to control the function marker in the second key group and to control the at least one dummy function marker moving between the keys of the second key group to be displayed if the second key group is selected by the key-group selecting command.

6. The display apparatus according to claim 1 , wherein the processor is configured to control the input marker and to control at least one dummy marker to be displayed in the first key group if the key corresponding to the function marker is selected.

7. The display apparatus according to claim 1 , wherein the processor is configured to control a region of the first key group where the input marker and to control at least one dummy marker are movable and a region of the second key group where the function marker is movable to be displayed on the UI of the on-screen keyboard.

8. The display apparatus according to claim 1 , wherein the processor is configured to control the at least one dummy marker to move in a direction different from a direction in which the input marker moves within the first key group.

9. The display apparatus according to claim 1 , wherein the processor is configured to control the at least one dummy marker to move successively in an ongoing second direction if the input marker moves two or more times successively in a first direction.

10. A method of controlling a display apparatus, the method comprising:
displaying a user interface (UI) including an on-screen keyboard, the on-screen keyboard comprising a first key group including keys corresponding to a plurality of letters and a second key group including keys corresponding to a plurality of functions;
receiving a key moving command for moving between keys of the on-screen keyboard displayed on the display;
displaying an input marker moving between first keys of the first key group in response to the key moving command and at least one dummy marker moving between second keys of the first key group if the first key group is selected by the key-group selecting command;
making an input of the first key if a first key corresponding to the input marker is selected;
displaying a function marker moving between keys of the second key group in response to the key moving command if the second key group is selected by the key-group selecting command; and
implementing a function of a key if the key corresponding to the function marker is selected.

11. The method according to claim 10 , wherein the key moving command and the key-group selecting command are issued by a remote controller comprising a plurality of buttons.

12. The method according to claim 10 , wherein the displaying the function marker comprises marking the function marker on a predetermined key of the second key group if the second key group is selected in response to the key-group selecting command.

13. The method according to claim 12 , wherein the predetermined key of the second key group corresponds to at least one of: a default key, a randomly selected key, a key just previously used by a user and a key used more frequently than a predetermined number of times.

14. The method according to claim 12 , further comprising: displaying the function marker in the second key group and displaying at least one dummy function marker moving between the keys of the second key group if the second key group is selected by the key-group selecting command.

15. The method according to claim 10 , further comprising: displaying the input marker and the at least one dummy marker in the first key group if the key corresponding to the function marker is selected.

16. The method according to claim 10 , further comprising: displaying a region of the first key group where the input marker and at least one dummy marker are movable and displaying a region of the second key group where the function marker is movable, on the UI of the on-screen keyboard.

17. The method according to claim 10 , further comprising: controlling the at least one dummy marker to move in a direction different from a direction in which the input marker moves within the first key group.

18. The method according to claim 10 , further comprising: controlling the at least one dummy marker to move successively in an ongoing second direction if the input marker moves two or more times successively in a first direction.

19. A computer program product comprising:
a memory configured to store instructions;
wherein the instructions, when executed by a computing device, cause the computing device:
to control a user interface (UI) of an on-screen keyboard, the on-screen keyboard comprising a first key group including keys corresponding to a plurality of letters and a second key group including keys corresponding to a plurality of functions, to be displayed on a display,
to control an input marker moving between first keys of the first key group in response to a key moving command and to control at least one dummy marker moving between second keys of the first key group to be displayed if the first key group is selected by a key-group selecting command,
to control an input of the first key to be made if a first key corresponding to the input marker is selected, to control a function marker moving between keys of the second key group in response to the key moving command to be displayed if the second key group is selected by the key-group selecting command, and
to control a function of a key to be implemented if the key corresponding to the function marker is selected.
