1 is a block diagram of a Korean input device provided with a general touch screen.

Referring to FIG. 1, the Korean input device including a touch screen includes a character combination means for combining the control unit 110 with an input window 120 for inputting a character and a character input by the touch screen by a predetermined process ( 130 and an output window 140 for controlling and displaying the characters combined by the character combination means 130, the input window 120 and the output window 140 is provided on the touch screen.

The present invention relates to the Hangul input device, the input window is provided with a terminal input, the first vowel 'l', and the second vowel '-' is independently arranged, the character combination means is a single touch Consonants and vowels are selected according to the touch characteristics, whether the touch is multi-touch or the touch direction, which is the drag direction of the touch, to combine Hangul.

Meanwhile, the single touch described in detail below means a general simple touch, and the multi-touch refers to a double touch in which two touches are performed by one touch operation and a touch is performed in two touch operations at specific time intervals. It will be regarded as a distinct touch action.

2 illustrates an embodiment of an input window of a Hangul input device according to an embodiment of the present invention.

That is, the character input key of the input window may have the input arrangement shown in FIG. 2, and may be variously configured according to the embodiment and the use environment.

Referring to FIG. 2, the letter input keys include the consonants of 'b, b, c, d, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅁ, ㅋ, ㅌ, ッ, ㅎ and vowels of' l, ㅡ '. Each is placed independently.

Based on the character input keys, the character combination means selects consonants and vowels according to the touch characteristics, whether the touch input by the user is single touch or multi-touch, and the touch direction, the drag direction of the touch, to combine Korean characters. do.

First, in order to input the letter of 'sa' based on the letter input key of FIG. 3, touch 'zy' consonant to input consonant 'ㅅ', then drag to the right to enter 'vo' Will complete the text.

That is, the dragging direction determines the vowel. Dragging to the right determines the 'ㅏ' vowel, and dragging to the left determines the 'vowel'. In the same way, dragging upwards determines the 'ㅗ' vowel, dragging downwards determines the 'TT' vowel.

Then, the input of the double consonants 'ㄲ, ㄸ, ㅃ, ㅆ' and the double vowel 'ㅑ, ㅕ, ㅛ, ㅠ' and the fold '' ㅐ, ㅒ, ㅔ, ㅖ, ㅘ, ㅙ, ㅚ, ㅝ, ㅞ, ㅟ , Input of ㅢ 'becomes a problem.

Input of double consonants and input of double vowels are as follows.

First, in order to input double consonants, a touch input is performed on the character input key of FIG. 2 by multi-touch instead of a single touch on a specific consonant.

Then, a single touch may be defined as a touch performed for input of a simple consonant, and a multi touch may be defined as a touch performed for input of a twin consonant.

The double vowels 'ㅑ, ㅕ, ㅛ, ㅠ' can be determined by the multi-touch action. That is, the dragging direction by the multi-touch determines the vowel. When dragging to the right with the multi-touch, the 'ㅑ' vowel is determined, and when dragging to the left with the multi-touch, the 'vowel' is determined. In the same way, dragging upward with multitouch determines the 'ㅛ' vowel, and dragging downward with the multitouch determines the 'ㅠ' vowel.

And, the input of the fold collection can be performed as follows.

The vowel of 'ㅐ' is determined by the single-touch input action by dragging the right side of a certain consonant, and the 'l' vowel is determined by touching the 'l' vowel on the character input key. The vowel of 'ㅐ' can be determined by combining the vowel of 'and the vowel of' l '.

The vowel of 'ㅒ' is determined by the multi-touch input action by dragging the right side of a certain consonant, and the 'l' vowel is determined by touching the 'l' vowel on the character input key. The combination of the vowel and the vowel of 'l' determines the vowel of 'ㅒ'.

In the same way, a collection of '모음', 'ㅖ', 'ㅚ' and 'ㅟ' can be determined.

A vowel of 'ㅘ' can be entered as shown in FIG. 4.

That is, for example, the input of '솨', for example, as described above, determine the 'ㅅ' consonant, dragging upward 311 to determine the 'ㅗ' vowel, dragging (312) to the right by continuous operation By determining the 'ㅏ' collection, it is possible to determine the 'vowel' by the combination of the 'vowel' and the 'vowel'. On the other hand, operation 311 and 312 are performed continuously. Finally, the character of '문자' can be determined.

As it is shown in Figure 4 to enter the vowel to determine the character of '솨' by dragging the area to enter the character input key of the other character 'c' by the dragging, the question about the possibility of error in the character input Can have

However, according to the present invention, since consonants are determined by touch and vowels are determined by a dragging action, even if a dragging action invades another consonant region, the present invention is not mistaken as an input of another consonant.

In summary, the input of the similar characters 'sa, sha, sa, sa, sa, shoot' is as shown in FIG.

That is, the letter of 'sa' is determined by the single touch of the 'ㅅ' consonant, the 'ㅅ' consonant, and the 'ㅏ' vowel is determined by the dragging of the single touch to the right 'sa' character is completed.

The consonant input mode is to determine the consonant input mode by the single touch of the consonant input. The consonant input mode is to determine the vowel by dragging the right touch of the single touch and the consonant determined by the consonant input mode. Hangul characters are completed by the combination of vowels determined by the vowel input mode.

In addition, the character of 'Sha' is determined by the single touch of the 'ㅅ' consonant, the 'ㅅ' consonant, and the 'ㅑ' vowel is determined by the dragging of the multi-touch to the right 'sha' character is completed.

On the other hand, the letter of 'Sai' determines the 'ㅆ' consonant by the multi-touch of the 'ㅅ' consonant, and the 'ㅏ' vowel is determined by dragging the right side of the single touch to complete the letter 'Sai'.

Then, the letter 'ㅆㅑ' determines the 'ㅆ' consonant by the multi-touch of the 'ㅅ' consonant, and the 'ㅑ' vowel is determined by the right dragging of the multi-touch to complete the 'ㅆㅑ' character.

Meanwhile, the character of 'shoot' determines the '결정' consonant by the multi-touch of the 'ㅅ' consonant, and the 'ㅘ' collection is determined by the upper dragging of the single touch and the continuous right dragging. Is completed.

On the other hand, according to another embodiment of the present invention, the character combination means is arranged on the touch screen terminal consonants and consonants of consonants, the touch characteristics of whether the single touch or multi-touch and the drag (drag) direction of the touch By determining the vowel according to the touch direction, Hangul can be combined by the selected consonants and vowels.

In addition, the input of the short vowel, the double vowel and the double vowel is the same as described above.
