combining key icons selected based on the multi-touch events to display a specific text prior to completion of an input of the specific text.

2. The method of claim 1, further comprising detecting drag events occurring when at least one of multi-touches moves in a predefined direction in a state where the multi-touches are maintained.

3. The method of claim 2, wherein the detecting of the drag events comprises at least one of:

detecting drag events occurring at a positioned point of the consonant from the text input area;

detecting drag events occurring at a positioned point of the vowel from the text input area; and

detecting reciprocation drag events dragged and reciprocated to a positioned point of at least one of the consonant and the vowel after a drag occurs in a predefined direction in a positioned point of at least one of the consonant and the vowel.

4. The method of claim 3, wherein the displaying of the specific text includes displaying a text created by adding strokes of a vowel to a vowel according to a direction of the drag event upon detecting the drag events occurring at a positioned point of the consonant, and a text composed of a combination of a consonant and a vowel selected at the time of multi-touches.

5. The method of claim 3, wherein the displaying of the specific text includes displaying a text obtained by adding strokes of a vowel to the selected vowel according to a direction of the drag event upon detecting the drag events occurring at a positioned point of the consonant, and a text combining a consonant selected at the time of multi-touches.

6. The method of claim 3, wherein the displaying of the specific text comprises:

adding strokes of a vowel to a vowel according to a direction of a drag event generated based on the selected consonant;

adding strokes to a corresponding vowel according to a direction of a drag event generated based on the selected vowel; and

displaying a text composed of a combination of the vowel having added strokes, the consonant, and strokes added to the vowel .

7. The method of claim 3, wherein the displaying of the specific text includes combining and displaying a vowel at the time of generating the reciprocation drag event, a double vowel including addition of strokes in a direction of the reciprocation drag event and the vowel , and a text including a consonant and a vowel selected at the time of the multi-touches.

8. The method of claim 1, further comprising activating a double consonant generation mode,

wherein the displaying of the specific text includes displaying a selected consonant as a double consonant when the consonant and a vowel are selected according to the multi-touch event at the time of activating the double consonant generation mode.

9. The method of claim 1, further comprising disregarding a display of a corresponding text when a text to be displayed prior to displaying the text is not included in a stored text data base list.

10. The method of claim 1, wherein the displaying of the text input area comprises:

displaying a vowel area including , and“

12. The method of claim 1, further comprising displaying currently touched key values and at least one complete text capable of being complete according to a drag direction when the multi-touch is dragged in a specific direction in a maintained state prior to input completion.

13. The method of claim 12, further comprising inputting the displayed text in a corresponding drag direction among the at least one displayed complete text when a touch cancellation event occurs after generation of an event to the drag direction.

14. A portable device comprising:

a touch screen including a display unit for displaying a text input area and a text display area including at least one consonant and vowel, and a touch panel provided at an upper side of the display unit for generating a touch event; and

a control unit for controlling text displayed according to a touch event generated from the touch screen,

wherein the control unit detects multi-touch events for at least two key icons output on the text input area, and controls the display of a specific text composed of a combination of the multi-touched key icons based on the detected multi-touch events.

15. The portable device of claim 14, further comprising a buffer for temporarily storing the multi-touch event and a drag event occurring in a state where the multi-touch is maintained.

16. The portable device of claim 15, wherein the buffer further stores at least one of:

a drag event occurring in a predefined direction at a positioned point of a consonant among the key icons in the state where the multi-touch is maintained;

a drag event occurring in a predefined direction at a positioned point of a vowel among the key icons in the state where the multi-touch maintained;

two drag events occurring in a predefined direction at positioned points of the consonant and the vowel among the key icons in the state where the multi-touch is maintained; and

a reciprocation drag event reciprocated to an initial position after a drag occurs in a predefined direction at a positioned area of at least one of the selected key icons in the state where the multi-touch is maintained.

17. The portable device of claim 16, wherein the control unit controls the display of a text obtained by adding strokes of a vowel according to the drag event direction to a vowel , and a text composed of a combination of a consonant and a vowel selected at the time of the multi-touch when a drag event occurs in the positioned point of the consonant;
