Abstract

A mobile terminal including a touchscreen configured to display a keypad including a plurality of key buttons having assigned first alphabet characters, respectively; and a controller configured to receive a first key input of a first key button of the plurality of key buttons, to display a first alphabet character corresponding to the first key input on a display portion of the mobile terminal, to predict a word that starts with the first alphabet character, to receive a second key input of the first key button after the first key input, and to display a second alphabet character included in the predicted word on the display portion based on the second key input.

Claims

1. A digital television comprising:

a display unit configured to display a keypad including a plurality of key buttons assigned with different alphabet characters, respectively; and

a controller configured to;

receive a first selection of a first key button of the plurality of key buttons,

input a first alphabet character assigned to the first key button in a text input box of the display unit,

predict a word that starts with the first alphabet character,

generate a first sub key button assigned with a second alphabet character of the predicted word on the keypad,

receive a second selection of the first sub key button, and

input the second alphabet character next to the first alphabet character in the text input box.

2. The digital television of claim 1, wherein the controller is configured to display the first sub key button to adjoin the first key button on the keypad.

3. The digital television of claim 2, wherein the controller is configured to display the first sub key button to partially overlap a second key button neighboring to the first key button.

4. The digital television of claim 1, wherein the controller is configured to display the first sub key button together with information about the predicted word on the display unit.

5. The digital television of claim 4, wherein the controller is configured to:

receive a third selection of the information about the predicted word, and

input the rest of the alphabet characters of the predicted word at the same time such that the rest of the alphabet characters are input next to the first and second characters in the text input box.

6. The digital television of claim 1, wherein the controller is configured to concurrently display both the first sub key button assigned with the second alphabet character and a third key button assigned with the same second alphabet character.

7. The digital television of claim 6, wherein the controller is configured to replace the first sub key button with a second sub key button assigned with the third alphabet character of the predicted word.

8. The digital television of claim 7, wherein the controller is configured to concurrently display both the second sub key button assigned with the third alphabet character and a fourth key button assigned with the same third alphabet character.

9. The digital television of claim 1, wherein the controller is configured to generate a second sub key button in addition to the first sub key button such that the second sub key button is concurrently displayed together with the first sub key button on the keypad.

10. The digital television of claim 9, wherein the controller is configured to display the second sub key button to adjoin the first sub key button on the keypad.

11. The digital television of claim 4, wherein the controller is configured to:

display the first and second alphabet characters of the predicted word in a first style, and

display the rest of the alphabet characters of the predicted word in a second style different from the first style.

12. A method of controlling a digital television, the method comprising:

displaying, via a display unit, a keypad including a plurality of key buttons assigned with different alphabet characters, respectively;

receiving, via a controller, a first selection of a first key button of the plurality of key buttons;

inputting, via the controller, a first alphabet character assigned to the first key button in a text input box of the display unit;

predicting, via the controller, a word that starts with the first alphabet character;

generating, via the controller, a first sub key button assigned with a second alphabet character of the predicted word on the keypad;

receiving, via the controller, a second selection of the first sub key button; and

inputting, via the controller, the second alphabet character next to the first alphabet character in the text input box.

13. The method of claim 12, further comprising:

displaying the first sub key button to adjoin the first key button on the keypad.

14. The method of claim 13, further comprising:

displaying the first sub key button to partially overlap a second key button neighboring to the first key button.

15. The method of claim 12, further comprising:

displaying the first sub key button together with information about the predicted word on the display unit.

16. The method of claim 12, further comprising:

concurrently displaying both the first sub key button assigned with the second alphabet character and a third key button assigned with the same second alphabet character.

17. The method of claim 16, further comprising:

replacing the first sub key button with a second sub key button assigned with the third alphabet character of the predicted word.

18. The method of claim 17, further comprising:

concurrently displaying both the second sub key button assigned with the third alphabet character and a fourth key button assigned with the same third alphabet character.

19. The method of claim 12, further comprising:

generating a second sub key button in addition to the first sub key button such that the second sub key button is concurrently displayed together with the first sub key button on the keypad.

20. The method of claim 19, further comprising:

displaying the second sub key button to adjoin the first sub key button on the keypad.
