Description

Korean character input device with 3 * 4 keypad {3 * 4 keypad}

The present invention relates to a Hangul character input device that can be applied to mobile products such as telephones, cellular phones, PDAs, etc., including other keypads with limited buttons (3 * 4), and other home appliances and remote controls requiring character input.

In order to arrange the phonemes of Korean characters on the 3 × 4 keypad, for the efficiency of character arrangement, it includes a mixed button for arranging consonants and vowels together. Press to use a two-key method for entering Korean phonemes.

Ahead of the ubiquitous era, where humans and machines communicate anywhere, anytime, the Korean character input method that enables P2M to instruct human commands on home appliances such as mobile communication terminals, remote controllers and MP3s Research and development continues.

In order to smoothly use a service that can instruct a human command on the machine, an indispensable thing will be a text input method that can be easily manipulated by the user. A keyboard layout that can be done is required.

Figure 1a is a phoneme on the keypad of 'Cheonjiin Hangul', characterized in that the vowel of Hangul composed of a combination of Cheon (天: '·), Ji (地:' ㅡ '), In (人:' ㅣ ') This is an array of characters. The 'Cheonjiin Hangul' is characterized by inputting 21 vowels used in Hangul by combining 'ㅣ', '·', 'ㅡ', and thus, three buttons (' ㅣ ',' · ',' ㅡ ') is enough. When inputting a vowel using 'Cheonjiin Hangul', it is not necessary to recognize the vowel keyboard separately, and then press the buttons in the same order as in writing. For example, if you press the button corresponding to '·', 'ㅡ', 'ㅣ', '·', you can enter. Therefore, the vowel input of 'Cheonjiin Hangul' can be called the one-key method.

In addition, as shown in FIG. 1A, the 'Cheonjiin Hangul' has two buttons arranged with '*' and '#' as the Hangul consonant, and three with the 'ㅣ', '·', and 'ㅡ' arranged. The seven buttons except for the button are 'ㄱ', 'ㄴ', 'ㄷ', 'ㄹ', 'ㅁ', 'ㅂ', 'ㅅ', 'ㅇ', 'ㅈ', 'ㅊ', 'ㅋ' , 'ㅌ', 'ㄷ', and 'ㅎ' are arranged in irregular pairs of two, '에' is placed on 'a' button, 'ㄸ' is placed on 'b' and 'ㅃ' Is placed on the button where 'ㅂ' is placed, 'ㅆ' is placed on the button where 'ㅅ' is placed, and 'ㅉ' is placed on the button where 'ㅈ' is placed.

When the consonants are input using the 'Cheonjiin Hangul', a multi-tap method of pressing a button on which the consonants to be input are arranged one to three times is used. For example, in the 4th button in which the 'ㄱ' and 'ㅋ' are arranged, pressing the '4' once, 'ㄱ', pressing twice, 'ㅋ', the button is not displayed, but pressing '번' three times Is entered.

The 'Cheonjiin Hangeul' has the advantage of not having to memorize the vowel keyboard separately, because the vowel keyboard can be entered as if writing a vowel, but the number of strokes increases because the vowel is separated into strokes. You can also use the multi-tap method

Since the consonant is input, especially when the consonant is input, the corresponding button needs to be pressed three times, so that the number of strokes increases in the case of a Chinese sentence having about 10 or more syllables. Also, one of the most used consonants, 'ㄴ' and 'ㄹ'

In order to enter the 'b' and 'ㄹ' button is frequently used, in particular, to enter 'ㄹ' frequently used as the finality of syllables, the button 'b' and 'ㄹ' There is a hassle to press to enter.

1b shows basic consonants ('ㄱ', b ',' ㄹ ',' ㅁ ',' ㅅ ',' ㅇ ') and basic vowels (' ㅏ ',' ㅓ ',' ㅗ ',' TT ',' It shows the character array of keypad used in 'EZ-Hangul' (hereinafter, 'EJ-Hangul'), which is a method of making letters by transforming and combining ㅣ ',' ㅡ ').

As shown in FIG. 1B, 'EJ-Hangul' denotes only the basic consonants on the buttons, and thus 'c', 'ㅂ', 'ㅈ', 'ㅊ' and 'ㅋ' are not included in the basic consonants. , 'ㅌ', 'ㄷ', 'ㅎ' uses a two-key method of transforming and inputting from the basic consonants by pressing a special key having a function of adding strokes. Accordingly, the consonants not included in the basic consonants are not marked on the button, and thus a relatively long time is required in order to use the 'Easy-Hangul'. In addition, when inputting a consonant consonant by pressing a special key having a function of transforming into a consonant after inputting the 'b', 'c', 'ㅂ', 'ㅅ', 'ㅈ' which is the basic type of the double consonant Use a two-key method to enter.

In addition, since the 'Easy-Hangul' is used as a button for inputting a vowel, a button marked only with 'ㅏ', 'ㅓ', 'ㅗ', 'TT', 'ㅡ' and 'ㅣ' is used. To input 'ㅑ', 'ㅕ', 'ㅛ', 'ㅠ', press the button that has 'ㅏ', 'ㅓ', ',', or 'TT', and then add the stroke. By using a special key that has a two-key method to transform the input from the default vowels.

The 'Easy-Hangul' is a Korean input method based on two-handed input, which has the advantage of being able to input Korean characters with only a few strokes compared to the 'Cheonjiin Hangul', but as already mentioned, the consonant and There is a vowel, familiar Hangul

There is a disadvantage in that it takes a lot of time to input a, and also a fingering distance (distance of finger movement) is large because a special key must be pressed in order to input consonants and vowels deformed from the basic consonants and basic vowels.

FIG. 2 shows the arrangement of Korean characters in a keypad in the patent registration No. 0431733, 'A Hangul input processing apparatus and method thereof suitable for a portable communication device using a reduced keypad' (hereinafter, 'vowel ten cross type Hangul input method'). . In FIG. 2, the basic consonants and the basic vowels are arranged on the remaining 10 buttons except for the buttons in which '*' and '#' are arranged. More specifically, 14 consonants are divided into five series, and the five buttons have ' A 'consonants (' ㄱ ',' ㄷ ',' ㅂ '),' b 'consonants' ('b', 'ㅁ', 't'), 'ㄹ' consonants ('ㄹ', 'ㅇ' , 'ㅋ'), 'ㅅ' consonant series ('ㅅ', 'ㅈ', 'ㅊ') and other consonants ('ㅎ', 'ㅌ'), and the buttons arranged with the other consonants Includes the function of a special key to transform to. In addition, the remaining five buttons include 'ㅣ' collection sequence ('ㅡ', 'ㅣ'), 'ㅗ' collection sequence ('ㅗ', 'ㅛ'), 'TT' collection sequence ('TT', 'ㅠ' ), 'ㅓ' vowel series ('ㅓ', 'ㅕ'), '모' vowel series ('ㅏ', '되'), but with 'ㅣ' vowel series (button 8) Button (buttons 5, 7, 9, 0)

Place the vowel button in. Looking at the input method of the vowel in the Hangul input method, the five phonemes follow the multi-tap method in which the phonemes are changed according to the number of key presses in the arrangement order.

The vowel crisscross type Hangul input device uses a multi-tap method for inputting consonants, a two-key method for inputting consonants among the consonants, and a multi-tap method for inputting vowels. Accordingly, the number of strokes required when entering a syllable is reduced compared to the 'Cheonjiin Hangul' and 'Easy-Hangul', but by arranging corresponding vowels on each of the five buttons, fourteen consonants are placed on the remaining five buttons. Because two or three consonants are placed on the button where consonants are placed

There is a disadvantage that a large number of strokes are required at the time of consonant input.

Therefore, users can effectively place Hangul consonants and vowels on limited buttons.

The time required to enter the syllables is short, even though it takes a while

There is a need for a Hangul input device, which has been reduced from the prior art.

Located under the Hereinafter, the Hangul batch as shown in FIG. 3B is specified as a field electronic Hangul batch that appears when combining the vowels arranged in the mixing button.

However, the method of arranging the consonant button, the vowel button, and the mixed button on the 3 * 4 keypad may include various methods, and it is obvious that the present invention may be included unless the technical spirit of the present invention is violated.

Figure 4 shows the device configuration of the present invention. As shown in FIG. 4, the present invention includes an input unit, a memory, and a syllable combining unit, and may further include a display unit.

The input unit includes a 3 * 4 keypad in which the consonants and vowels of the Hangul described above are disposed.

The memory stores Korean phonemes and includes a vowel font storage area and a consonant font storage area. The vowel font storage area is' ㅏ ',' ㅓ ',' ㅗ ',' TT ',' ㅡ ',' ㅣ ',' ㅑ ',' ㅕ ',' ㅛ ',' ㅠ Korean, including ',' ㅐ ',' ㅒ ',' ㅔ ',' ㅖ ',' ㅘ ',' ㅙ ',' ㅚ ',' ㅝ ',' ㅞ ',' ㅟ 'and' ㅢ ' Store fonts for 21 vowels. In addition, the consonant font storage area is used as a consonant and finality in Korean syllables' ㄱ ',' ㄴ ',' ㄷ ',' ㄹ ',' ㅁ ',' ㅂ ',' ㅅ ',' ㅇ ',' ㅈ, ㅋ, ㅋ, ㅌ, ㅍ, ㅎ, ㄲ, ㄸ, ㅃ, ㅆ, ㅉ and ㄳ It stores fonts for 28 consonants in Korean, including ',' ㄺ ',' ㄻ ',' ㄼ ',' ㄽ ',' ㄾ ',' ㄿ ',' ㅀ 'and' ㅄ '.

The syllable combining unit obtains fonts for phonemes received from the input unit from a memory, and combines a plurality of fonts read from the memory into one syllable based on an input order and a Hangul spelling method. In addition, the plurality of phonemes

It plays the role of transmitting the syllable composed by combining to the display unit.

When the syllable combiner presses a consonant button in the input unit, the consonant consonant arranged in the consonant button is read from the consonant font storage area of the memory. The consonant button, as described above, three consonants are arranged, according to the number of times to press the consonant button

The fonts to be loaded from the list are different. That is, pressing the consonant button once brings up the font for the consonant shown first on the left side of the consonant button, and pressing the consonant button twice brings up the font for the consonant shown second on the right side of the consonant button. When the consonant button is pressed three times, a font for the double consonant arranged in the consonant button is called up.

For example, the syllable combination unit reads the font for 'c' from the consonant font storage area by pressing the 'ㄷ ㄹ' consonant button once, and pressing the 'ㄹ' consonant button twice. The font for is read from the consonant font storage area. When pressed three times, the font for 'ㄸ' is read from the consonant font storage area.

In the Hangul input device proposed by the present invention in inputting a consonant, as described above, after pressing the consonant button and the multi-tap method of reading the font for the consonant arranged in the consonant button three times by pressing the consonant button three times By pressing a special button to perform a consonant conversion, it is characterized by using a two-key method that reads the font for the double consonants arranged in the consonant button. Conventionally, when inputting a pair of consonants, either a multi-tap method or a two-key method is selected and used. Therefore, when a user uses a Hangul input device using a multi-tap method and uses a Hangul input device using a two-key method or vice versa, In this case, there is a problem in that it takes a long time to use the Hangul input device. In the present invention, by using the multi-tap method and the two-key method can be used in combination, the user can be used in a method that has already been used to reduce the time required to use the Hangul input device familiar It was. In addition, while using the multi-tap method has a disadvantage in that the number of strokes is increased, while the fingering distance is not large, on the contrary, in the case of using the tucky method, the number of strokes is reduced while the fingering distance is increased. If it is selected and used in a convenient way, the time and effort required to input Hangul can be reduced according to the user.

The special button for converting the consonants into a consonant may be used by selecting one of '*' arranged in the left button of the fourth row where consonants and vowels are not arranged or '#' arranged in the right button of the fourth row. Can be.

The syllable combining unit reads a font from the vowel font storage area of the memory with respect to the vowel disposed in the vowel button. As mentioned above, the vowel button is arranged with 'ㅡ', 'ㅣ', 'ㅢ', and the vowel button once

Pressing it reads the font for 'ㅣ', twice for the font for 'ㅡ', three times for reading the font for 'ㅢ' from the vowel font storage area. Since 'ㅣ' is used more than 'ㅡ', pressing the vowel button once reads the font for 'ㅣ'. The 'ㅢ' is a multi-tap method of reading the font for the 'ㅢ' by pressing the vowel button three times, and pressing the vowel button once and then pressing the special button to perform the function of double consonant conversion to the 'ㅢ'. You can use a combination of two-key method of reading the font.

In addition, when the mixing button is input, the syllable combining unit loads from the memory first from the component phonemes necessary for constructing the syllable according to the input value before the mixing button is input.

Hangul syllables consist of consonants, neutrals and species. The initial and final stars are formed by consonants, and the neutral is composed by vowels. If there is no initial or neutral, it is preferable to receive a vowel to form a desirable syllable.

On the contrary, when there is no primary or neutral, it is preferable to receive consonants for more preferable syllables. According to the present invention, the order of inputting consonants and vowels of the mixing button is changed according to the condition before inputting the mixing button using the Hangul spelling method as described above. However, in a special case, since a content that does not match the Hangul spelling may be input, the syllable combining unit reads a font matching the phoneme input by the mixing button from the memory according to the Hangul spelling as well as the input order.

For example, when the 'TT 혼합' mixing button of the crisscross Hangul arrangement (FIG. 3A) is described as an example, if 'ㅋ' is input before the 'TT ㅌ' button is pressed, the 'ㅋ' is a consonant or a consonant. You can judge. In addition, since there is no vowel used as a finality, it is preferable that the vowel 'TT' or 'ㅠ' be input based on the Hangul spelling. Therefore, the syllable combining unit presses the 'TT 혼합' mixing button once to bring up the font for 'TT' and press twice for the font for 'ㅠ' from the vowel font storage area. If the special case does not comply with the Hangul spelling, that is, the user intends to input consonants, the syllable combining unit reads the font for 'ㅌ' from the consonant font storage area by pressing the 'TT' mixing button three times.

If 'ㄱ' and 'ㅏ' were sequentially input before receiving the 'TT' button, the ',' may be determined to be neutral since it is a vowel. Therefore, the syllable combiner reads the font for 'ㅌ' from the consonant font storage area by pressing the 'TT' button once, and presses the font for 'TT' twice, and presses the font for 'ㅠ' three times. Read from storage.
