Description

TECHNICAL FIELD The present invention relates to a method and apparatus for inputting Korean characters using touch and drag,

The present invention relates to a Hangul input method. More particularly, the present invention relates to a method and apparatus for inputting Korean characters using a touch-and-drag method of inputting Korean characters through a selective combination of a touch and a drag.

The characters in the world are separated by a tabular character and a phonetic character. Hangul belongs to a phonetic character. Hangul consonants were made scientifically by applying pronunciation agency. In addition, the Hangul vowels are based on the heavenly people, and contain philosophical meaning.

Hangeul, which has scientific and philosophical implications, can also be scientific and logical. As an example, a basic vowel consisting of 'ㄱ', 'ㄴ', 'ㄷ', 'ㅁ', 'ㅅ', 'ㅇ' and 'ㅡ', 'ㅣ' All consonants and vowels can be created. For example, 'ㅋ' and 'ㄲ' can be generated according to a continuous tag of 'a', 'd' can be generated according to a continuous tag of 'b' It can generate 'ㅌ' and 'ㄸ' according to the category, and can generate 'py' and 'ㅃ' according to the successive category of 'ㅂ', and ' , 'ㅆ' can be generated, and 'Ĉ' and 'ㅉ' can be generated according to the successive tag of 'ゃ', and 'ㅁ' can be generated according to the successive tag of 'ㅇ'. On the other hand, in the case of a vowel, all the vowels can be generated corresponding to the input order and the number of touches of the basic vowel.

However, such an input method provides scientific logic of character combination, but has a disadvantage in that the number of touches increases.

On the other hand, smartphones are becoming more and more common necessities. That is, a smart phone is used not only as a device for personal management but also as a task processing because it can perform almost all the functions that a computer such as a desktop and a notebook computer can perform.

In such a smartphone, various keypads are provided to support user's convenience. That is, the user can select and use a desired keypad among various keypads.

However, while smartphones have strengths of portability, their size is limited. This also limits the screen size. Accordingly, when the number of input keys of the keypad selected by the user is large, the size of the input key becomes small, so that it is difficult to input the key correctly. Although the keypad screen can be rotated in response to the rotation of the smartphone, the keypad screen can be extended in the horizontal direction, but there is a limit to expand the size of the input key.

In case of a QWERTY keypad (keyboard) connected to a desktop and a notebook, each phoneme of a consonant and a vowel corresponds to one input key, so that it is possible to input quickly and accurately if skilled. However, It is difficult to arrange the keypad in an environment where the screen size is limited, and the size of the input key becomes very small. Moreover, the unskilled person has the inconvenience of memorizing and practicing the input keys.

Hereinafter, an exemplary embodiment of a method and apparatus for inputting Korean characters using touch and drag according to the present invention will be described with reference to specific embodiments.

1 is a block diagram of a Korean input device using touch and drag according to an embodiment of the present invention.

Referring to FIG. 1, the Korean-language input device using touch and drag according to the present invention includes an input key determination unit 1 for determining an input key selected by a user's touch, A consonant phoneme of a consonant phoneme of the input key determination unit 1 and a consonant phoneme of an input key tracing unit or a phoneme generation unit which generates a final phoneme by selecting a vowel phoneme of an input key tracing unit And an input key expansion unit 4 for expanding the input key from the vowel phonemes of the input key determination unit 1 and the vowel phonemes of the input key tracing unit.

Here, the Hangul input device using the touch and drag according to the present invention can be applied to a smart phone or the like, and the input key can be determined according to the coordinate value input from the touch screen (touch pad).

Here, 'touch' means that a finger or a pen touches the touch screen and is spaced apart, and 'drag' means that the 'touch' includes an area of another input key.

The Korean-language input device using the touch and drag according to the present invention configured as described above is capable of automatically executing a Hangul input device in response to a user's operation of inputting a message or the like, do. Coordinate values are generated from the touch screen in response to the user's touch and transmitted to the Hangul input device. The input key determination unit (1) of the Korean input apparatus determines the input key selected by the user. When the user continuously touches the touch screen with the finger or the pen touched, the input key tracking unit 2 tracks the input key to be dragged. When the user releases the contact state, i.e., separates the finger or the pen from the touch screen, the phoneme generation unit 3 generates a consonant phoneme of the input key determination unit 1 and consonant phonemes of the input key tracking unit And in the case of a vowel, a consonant phoneme of the input key tracking unit is selected to generate a phoneme.

On the other hand, in the case of a Hangul vowel, the input key is expanded from the phoneme of the input key determination unit 1 and the phoneme of the input key tracing unit and output to the screen. That is, the input key expansion unit 4 outputs the phonemes extended from the phoneme first selected by the input key determination unit 1 or outputs phonemes extended from the phonemes tracked by the input key tracing unit.

On the other hand, the consonant input key and the vowel input key are preferably arranged on one screen, and they can be arranged in the vertical direction or the horizontal direction. Of course, the consonant keypad and the vowel keypad may be sequentially switched in consideration of the screen size. It is preferable that the consonant keypad and the vowel keypad are switched when the finger or pen is separated from the touch screen.

Hereinafter, a method of inputting a Korean-language using touch and drag according to the present invention using the Hangul input device configured as described above will be described.

FIG. 2 is a flowchart illustrating a method of inputting a Korean character using touch and drag according to an exemplary embodiment of the present invention.

Referring to FIG. 2, a Hangul input device is executed in response to a user operation such as message input (S1).

Then, the consonant keypad and the vowel keypad are displayed on the screen (S2).

The user touches a desired consonant or vowel by using a finger or a pen or performs a drag operation for a combination (consonant) or selection (vowel) of the phoneme following the touch. At this time, the end of the touch and drag operation is caused by the separation of the finger or the pen from the touch screen.

On the other hand, the input key determination unit 1 of the Hangul input device determines an input key selected by the user in response to the user's operation (S3). Then, the input key tracking unit 2 tracks another input key that is dragged and selected (S4). Subsequently, the phoneme generating unit 3 generates phonemes by combining consonant phonemes of the input key determination unit 1 and consonant phonemes of the input key tracing unit (S5). On the other hand, the phoneme generation unit 3 selects phonemes of the input key tracing unit to generate phonemes (S5). The generated phoneme is output to the touch screen (S6).

Here, the process of generating phonemes of consonants and vowels will be described in detail.

3 is a diagram illustrating a process of generating phonemes of consonants according to an embodiment of the present invention.

Referring to FIG. 3, first, it is determined whether a specific consonant phoneme is touched (S11).

If only a specific consonant phoneme is touched (S12), the specific consonant phoneme is output (S13).

On the other hand, while the contact state is maintained on the touch screen, it is determined whether or not the specific consonant phonemic region is moved to another consonant phonemic region (S14).

If it is determined that another consonant phonemic region has been entered, a specific consonant phoneme and a current consonant phoneme are combined (S15). At this time, the process of entering another consonant phoneme area may be repeated for phoneme combination.

When the touch state is ended after dragging (S16), consonant phonemes are synthesized by combining consonant phonemes reaching the final consonant phoneme from a specific consonant phoneme (S17).

On the other hand, in order to generate phonemes of consonants through touching, dragging, and continuous dragging, consonant keypads should be arranged based on the order of writing consonant part strokes. The arrangement of the consonant keypad will be described with reference to FIG.

4 is a diagram illustrating a phoneme generation process of a vowel according to an exemplary embodiment of the present invention.

Referring to FIG. 4, first, it is determined whether a specific vowel is touched (S21).

When a specific vowel phoneme is touched, a phoneme of an inputable vowel extending from the specific vowel phoneme is output (S22).

At this time, if only the touch is performed for a specific vowel phoneme (S23), the specific vowel phoneme is output (S24).

On the other hand, it is determined whether the user has entered another vowel phoneme area beyond the specific vowel phoneme area while maintaining the contact state on the touch screen (S25).

If it is determined that another vowel phoneme area has been entered, the phonemes of the input vowel extended from the other vowel phonemes are output (S26).

At this time, if only the touch of the other vowel phonemes is performed, the corresponding other vowel phonemes are output. That is, when the vowel phonemic region is expanded through dragging, the process of outputting the phonemes of the input vowel extended from the corresponding vowel phoneme is repeated. Further, if the extended vowel phoneme is the last expansion stage, no further expansion is performed.

Thereafter, when the final vowel phoneme is selected (touch completion) in the expanded vowel phoneme (S27), the final vowel phoneme is output (S28).

On the other hand, in order to generate phonemes of a vowel through touch, drag, and continuous dragging, the vowel keypad should have a basic vowel arranged in the upper, lower, left, and lower left portions based on the "ㅣ". The arrangement of the vowel keypad will be described with reference to Fig.

5 is a view showing a consonant keypad.

Referring to FIG. 5, the consonant cap pad is used to generate consonant phonemes through touch, drag, and continuous dragging,

'A' is placed on the upper part of 'ㅡ'

'B' is placed at the bottom of '

'And' ', which are common to' a 'and' a '

',' Which is common to 'ㅡ' and 'ㄴ'

'=' Is placed in common to 'a' and 'g', and '

Quot; and " o " which are in common contact with " l " and "

Quot; x2 " in common with the " I ", " a &

Place 'x2' in common with 'o', 'b', and 'g'.

Here, it is set to generate 'f' in response to the touch of 'I', to generate 'I' in response to the touch of '', and to generate 'he' in response to touch of '=' Setting. That is, it is sufficient to memorize only the touch values of 'ㅣ', 'ㅡ' and '=', and preferably display the touch values of 'ㅣ', 'ㅡ' and '=' on the screen.

Thus, the consonant keypad arranged in consideration of the handwriting order of each consonant can generate phonemes of all consonants.

6 is a diagram illustrating a method of generating consonants according to the order of writing consonant part strokes.

Referring to FIG. 6, the consonant phonemes according to the present invention are applied in accordance with the order of writing the partial strokes. Intuitive input is possible and is arranged so that all consonants can be input through continuous dragging. That is, the consonant keypad is not composed of only consonants, but generates consonants by combining partial strokes ('ㅣ', 'ㅡ' and '=') included in the handwriting sequence with consonants. In addition, 'x2' (horn symbol) is used to generate audible sound. In other words, consonants are formed through the handwriting sequence and the one-way progress of the drag.

As described above, the partial strokes constituting each consonant are arranged adjacent to each other. Therefore, when implemented with a touch screen, consonant phonemes are generated through touching, dragging, and continuous dragging without releasing a finger or a pen. At this time, since one or more input keys are sequentially selected and combined, it is necessary to judge input start and end of input. In the case of a touch screen, it is determined that the corresponding consonant is completed at the time of separating a finger or a pen.

On the other hand, as described above, 'f', 'x', and 'h' can complete the input with only partial strokes.

'ㅁ' means you can input all three part strokes, or you can enter only the second part stroke. That is, if the input order of the touch and drag is not the same, an abbreviated form of input can be made possible.

7 is a diagram showing an initial state of the vowel keypad.

Referring to FIG. 7,

'' 'Is placed on the upper part of the' ㅣ '

'ㅜ' is placed under 'ㅣ'

'ㅓ' is placed on the left side of 'ㅣ'

'A' is placed on the right side of 'ㅣ'

Place 'ㅡ' which is common to 'ㅓ' and 'ㅜ'.

In this way, the vowel keypad displays only the six vowels of 'ㄱ', 'ㅓ', 'ㅗ', 'ㅜ', 'ㅡ', and 'ㅣ' on the nine keypads at the initial state.

When the corresponding six vowels are touched by touching the corresponding input key, the generation of the vowel phoneme is completed.

On the other hand, if the finger or pen is not touched while touching the vowels of 'a', 'ㅓ', 'ㅗ', and 'ㅜ', the arrangement of the input keys is changed so that the phonemes of the other vowels can be selected.

The vowel keypad has the following characteristics.

1. You can enter one vowel by touching it without releasing your finger.

(However, a combination of horizontal and vertical lines such as 'ㅘ', 'ㅙ', 'ㅚ', 'ㅝ', 'ㅞ', 'ㅟ', and 'ㅢ' It is the same as the keyboard input method of Hangul2)

2. In the initial state, only the basic vowels are displayed so that even the beginner can easily find the desired key without being embarrassed.

3. The process of expanding from a basic form of vowel to a complex form of vowel has a consistent rule so that it can be easily adapted with little learning.

- Touch the vowel of 'ㅗ', 'ㅜ', 'ㅓ', 'ㄱ' in the upper, lower, left and right positions and move in one of the four corners to touch 'ㅛ', 'ㅠ', 'ㅕ' , And 'ㅑ'.

- If you move to the middle vertical line, a vertical stroke is added ('ㅐ', 'ㅔ', 'ㅒ', 'ㅖ').

8 is a view illustrating a keypad extended in a state in which 'a' is touched.

Referring to FIG. 8, when 'a' is touched, 'ㅑ' is arranged on the upper and lower sides of 'a', and 'ㅐ' is outputted on the left of 'a'.

In this extended state, when a finger or a pen is released immediately from the position of 'a', 'a' is inputted, and when a finger or a pen is released after moving to the positions of 'ㅑ' and 'ㅐ' '.

On the other hand, 'ㅑ' is arranged two vertically so that user convenience is considered.

FIGS. 9 and 10 are diagrams showing a keypad extended in a state of touching '.'

Referring to FIG. 9, 'ㅑ' is input when the finger is released immediately from the position of 'ㅑ', and 'ㅒ' is entered when the finger is released after moving to the position of 'ㅒ'.

At this time, if the finger is not lifted after moving to the position of 'ㅑ', the arrangement of the keypad corresponding to the drag direction is expanded as shown in FIG. 9 or 10.

11 is a view showing a keypad extended in a state of touching 'ㅓ'.

Referring to FIG. 11, when 'ㅓ' is touched, 'ㅕ' is arranged at the top and bottom of 'ㅓ', and 'ㅔ' is outputted at the left of 'ㅓ'.
