5 is a flowchart for displaying an input result of a drag operation and a down-up operation in the input window of FIG. 2 on a display window of a touch screen.

In the process as shown in FIG. 5, the principle of configuring and displaying Korean characters by dragging and down-up using the input window displayed as shown in (1) of FIG. 2 will be described in detail.

When the keyboard is touched in the input window where the buttons of the phonemes (consonants and vowels) are arranged, the consonants of the touched buttons are recognized and displayed as initials, the coordinates of the drag operation are memorized, and the drag ends. Comparing and analyzing the drag coordinate values and the vowel values stored in the DB, the vowel corresponding to the drag is recognized as neutral and displayed in the output window. In this state, the vowel button or the consonant button is down-up. If it is selected by the operation, the vowel is recognized as a vowel in the double vowel or the consonant is recognized as a consonant and displayed in the output window, and after the button marked 'pair' is operated down-up, the consonant button on the keyboard When touched, the consonants are recognized as twin consonants and displayed on the output window.

If you explain this with letters,

If you want to display the 'bot', as shown in (10) of Figure 2, the keyboard 'ㅂ' of the input window is displayed (down), the phone bar '(' immediately dragged up (up). That is, the starting point of the drag is 'ㅂ', and the coordinate values of the drag become 'ㅗ' so that the system is configured to display 'beam' on the display unit 4.

In the case of displaying 'Bok', the system is configured to display 'Bok' on the display unit 4 when the down and up (ie, touch) are performed in the coordinate area of 'B' in the 'Bo' state.

In the case of displaying 'look', the system is configured to display 'look' on the display unit 4 when down and up (touch) are performed in the coordinate region of 'ㅏ' in the 'beam' state.

In order to display 'po', the system is configured to display 'po' on the display unit 4 by dragging the 'bo' after down and up (touch) in the coordinate area of the pair.

When displaying '하고자', the system is configured to display '되도록' on the display unit 4 by dragging from the coordinate area of 'ㅂ' to the shape of 'ㅛ' as shown in (11) of FIG. 2.

In addition, as shown in (3) of FIG. 3, when the system starts by dragging the shape of the vowel 'down' at the 'c' of the input window, the system is configured to display the 'large' on the display unit 4.

In summary, in the case of inputting an example of a word, for example, "our country", when the user drags as shown in (1) of FIG. 4, it appears on the display unit 4.

In the case of inputting the 'website', the user appears on the display unit 4 when dragging and down-up (down-up) as shown in FIG.

The above input method is an example of recognizing a vowel by comparing and analyzing coordinate values moved by dragging.

However, the recognition rate can be accurately corrected by converting the variation value according to the coordinate movement into the movement of each unit of the button by making the same recognition value in the rectangular phone (button) of one phoneme displayed in the input window. .

By applying the upright square button as described above, a keyboard having a phoneme (consonants and vowels) is arranged diagonally as a rhombus square button as shown in FIG. 6, so that the moving distance may be shortened and the recognition rate may be increased.

In the present invention, the consonant a, b, c, d, ㅁ, ㅂ, ㅅ, ㅇ, ㅅ, ㅋ, ㅌ, ッ, ㅎ and vowels ㅓ, ㅓ, ㅐ. It has a screen, and the starting point of the drag is selected and displayed, the neutral is selected and displayed according to the drag shape from the starting point to the ending point of the drag, and the added bar or the base is added by a down-up operation. Since it is configured to be selected and displayed, the input is quick by dragging only the neutral without the initial input, and the screen is simple by omitting the vowel arrangement, and the recognition speed is fast and the recognition rate can be increased by allowing only the vowel to be recognized. . That is, the present invention can easily implement the keyboard with a few buttons compared to the method of displaying both consonants and vowel buttons among the conventional methods of inputting Hangul on the touch screen, and recognizes only vowels compared to the method of recognizing characters. Because of this, there is an advantage that can greatly improve the recognition speed and recognition efficiency.
