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 mobile terminal comprising:

a touchscreen configured to display a keypad including a plurality of key buttons each button having assigned a different alphabet character; and

a controller configured to receive a first key input of a first key button of the plurality of key buttons of the keypad, to display a first alphabet character originally assigned to the first key button 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 of the keypad consecutively after the first key input, and to display a second alphabet character different from the first alphabet character included in the predicted word on the display portion based on the second key input,

wherein the controller is further configured to, in response to receiving the first key input of the first key button, change a display of the first key button from the first alphabet character to the second alphabet character while maintaining displaying alphabet characters originally assigned to the rest of the key buttons of the plurality of key buttons on the rest of the key buttons, respectively.

2. The mobile terminal of claim 1, wherein the controller is further configured to receive a third key input of the first key button after the second key input, and to display a third alphabet character included in the predicted word on the display portion based on the third key input.

3. The mobile terminal of claim 1, wherein the controller is further configured to configured to change the display of the second alphabet character on the first key button back to the first alphabet character.

4. The mobile terminal of claim 1, wherein the controller is further configured to distinctively display a second key button identifying the second alphabet character of the predicted word.

5. The mobile terminal of claim 1, wherein the controller is further configured to display a pop up window including the second alphabet character of the predicted word near the first key button.

6. The mobile terminal of claim 5, wherein the controller is further configured to display the second alphabet character included in the predicted word on the display portion if the pop-up window is selected.

7. The mobile terminal of claim 1, wherein the controller is further configured to distinctively display at least the second alphabet character of the predicted word on the display portion before the second key input.

8. The mobile terminal of claim 7, wherein the controller is further configured to receive a touch input corresponding to a selection of the distinctively displayed second alphabet character on the display portion and to non-distinctively display the second alphabet character on the display portion based on the received touch input.

9. The mobile terminal of claim 1, wherein the controller is further configured to display an indicator indicating that a plurality of predicted words are available for selection that start with the first alphabet character.

10. The mobile terminal of claim 1, wherein the controller is further configured to display all characters of the predicted word on the display portion based on the first key input, and to receive a predetermined touch input indicating a selection of the displayed predicted word.

11. The mobile terminal of claim 10, wherein the predetermined touch input includes one of a long touching operation, a double touching operation, and a touch and dragging operation.

12. A method of controlling a mobile terminal, the method comprising:

displaying, on a touchscreen of the mobile terminal, a keypad including a plurality of key buttons, each button having assigned a different alphabet character;

receiving, via a controller on the mobile terminal, a first key input of a first key button of the plurality of key buttons of the keypad;

displaying, on a display portion of the mobile terminal, a first alphabet character originally assigned to the first key button based on the first key input;

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

receiving, via the controller, a second key input of the first key button of the keypad consecutively after the first key input;

displaying, on the display portion, a second alphabet character different from the first alphabet character included in the predicted word based on the second key input; and

changing, in response to receiving the first key input of the first key button, a display of the first key button from the first alphabet character to the second alphabet character while maintaining displaying alphabet characters originally assigned to the rest of the key buttons of the plurality of key buttons on the rest of the key buttons, respectively.

13. The method of claim 12, further comprising:

receiving, via the controller, a third key input of the first key button after the second key input; and

displaying, on the display portion, a third alphabet character included in the predicted word based on the third key input.

14. The method of claim 12, further comprising:

changing, via the controller, the display of the second alphabet character on the first key button back to the first alphabet character.

15. The method of claim 12, further comprising:

distinctively displaying, via the controller, a second key button identifying the second alphabet character of the predicted word.

16. The method of claim 12, further comprising:

distinctively displaying, via the controller, at least the second alphabet character of the predicted word on the display portion before the second key input;

receiving, via the controller, a touch input corresponding to a selection of the distinctively displayed second alphabet character on the display portion; and

non-distinctively displaying, via the controller, the second alphabet character on the display portion based on the received touch input.

17. The method of claim 12, further comprising:

displaying, via the controller, an indicator indicating that a plurality of predicted words are available for selection that start with the first alphabet character.

18. The method of claim 12, further comprising:

displaying, via the controller, all characters of the predicted word on the display portion based on the first key input; and

receiving, via the controller, a predetermined touch input indicating a selection of the displayed predicted word.
