Description

Korean language Input Device for a Product containing 3 × 4 Keypad}

1 illustrates the arrangement of Korean consonants and vowels on a keypad in the conventional Korean input methods 'Cheonjiin Hangul' and 'Easy-Hangul'.

Figure 2 shows that the consonants and vowels of the Hangul arranged on the keypad in the vowel crisscross Hangul arrangement.

3 is a block diagram of consonants and vowels arranged on a 3 × 4 keypad in the input unit of the Hangul character input device of the present invention.

Figure 4 shows the device configuration of the present invention.

The present invention relates to mobile products such as telephones, portable telephones, cellular-phones, personal digital assistants (PDAs), including keypads (key-pads) with limited buttons (3 × 4); The present invention relates to a Hangul character input device that can be applied to other home appliances (remote control) and the like that require character input. More specifically, in the arrangement of the phonemes of the Hangul in the 3 × 4 keypad, for the efficiency of the character arrangement, including a consonant mixed buttons for arranging consonants and vowels, phonemes input according to the number of times the button is pressed The multi-tap method is changed and the two-key method of inputting Korean phonemes by pressing two buttons is used.

Ahead of the ubiquitous era of 'communication between humans and machines at any time', the P2M (Person to Machine), which directs human commands to home appliances such as mobile communication terminals, remote controllers and MP3s, is realized. Hangul) character input method '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 vowels of Hangul composed of a combination of 天 (天: ' · '), ji (地: 'ㅡ'), In (人: 'ㅣ') This is an array of characters. The 'Cheonjiin Hangul' is characterized by inputting 21 vowels used in Korean by combining 'ㅣ', ' · ', 'ㅡ', and thus, three buttons (' ㅣ ',' · ',' ㅡ ') is enough. When inputting a vowel using the 'Cheonjiin Hangeul', it is not necessary to recognize the vowel keyboard separately, the button in the same order as when writing. Take 'ㅘ' as an example and press the button corresponding to ' · ', 'ㅡ', 'ㅣ', ' · ' to input. Therefore, the vowel input of 'Cheonjiin Hangul' can be referred to as the one-key method.

In addition, as shown in Figure 1a, the 'Cheonjiin Hangul' has two buttons arranged with '*' and '#' of Hangul consonants and three arranged with 'ㅣ', ' · ', 'ㅡ' 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, 'ㄲ' is placed on the button with 'ㄱ' and ',' is placed on the button with 'ㄷ''버튼' is placed on the button where 'ㅂ' is placed, 'ㅆ' is placed on 'button' and 'ㅉ' is placed on the button.

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

The 'Cheonjiin Hangeul' has the advantage that you do not need to memorize the vowel keyboard separately because you can press the button as if writing a vowel, but the number of strokes increases because the vowel is separated into strokes. In addition, since the consonant is input using the multi-tap method, when a double consonant (double consonant) is input, the corresponding button has 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. In addition, by placing one of the most commonly used consonants 'b' and 'ㄹ' into one button, the buttons 'b' and 'ㄹ' are frequently used, and 'ㄹ' which is often used as a final syllable. In order to enter, there is a hassle to input by pressing the button 'b' and 'ㄹ' arranged twice.

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 in which a special key having a function of adding strokes is pressed to input from the basic consonants. 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 double consonant (double consonant), by pressing the special key having the function of transforming into a double consonant after entering 'ㄱ', 'ㄷ', 'ㅂ', 'ㅅ', 'ㅈ', which is the basic form of the double consonant Two-Key method is used to input double consonants.

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. In order to input 'ㅑ', 'ㅕ', 'ㅛ', 'ㅠ', press the 'ㅏ', 'ㅓ', 'ㅗ', 'TT' button, and then add the stroke. By using a two-key method to transform the input from the default vowel by pressing a special key that has.

The 'Easy-Hangul' is a Hangul input method based on two-handed input, which has the advantage of being able to input Korean with only a few strokes compared to the 'Cheonjiin Hangul', but as already mentioned, consonants and vowels not displayed on the button There is a disadvantage that it takes a lot of time to enter the Hangul familiarly, and also the fingering distance (the distance the finger moves) because you need to press a special key to enter consonants and vowels that are transformed from the basic consonants and basic vowels. It has a big disadvantage.

Table 1 shows the number of strokes when inputting the same sentence in the prior art, respectively.

In constructing Table 1, the Korean spacing was not considered, and the 'Cheonjiin Hangul' did not consider the necessary cursor movement when there were repeated consonants.

As shown in Table 1, in the case of 'Cheonjiin Hangul' (FIG. 1A), 13 strokes are required to enter a short sentence ('I love you'), and 26 strokes are required to enter a Chinese sentence ('Call me now'). You need 52 strokes to enter a long sentence ('I'll be late, please wait a bit'). In addition, in the case of 'Easy-Hangul' (FIG. 1B), 13 strokes are required to input a short sentence, 24 strokes are required to input a Chinese sentence, and 47 strokes are required to input a long sentence. Therefore, the vowels are separated and input in one-key mode, and the consonants are input in syllables that the 'Eo-Hangul' uses the two-key method of modifying and combining the basic consonants and the basic vowels rather than the 'Cheonjiin Hangul' inputted in the multi-tap method. As the number of numbers increases, the number of strokes decreases.

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, basic consonants and 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 five buttons 'ㄱ' consonant series ('ㄱ', 'ㄷ', 'ㅂ'), 'b' consonant series ('ㄴ', 'ㅁ', 'ㄷ'), 'ㄹ' consonant series ('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 special keys that transform to sound. In addition, the remaining five buttons include 'ㅣ' collection sequence ('ㅡ', 'ㅣ'), 'ㅗ' collection sequence ('ㅗ', 'ㅛ'), 'TT' collection sequence ('TT', 'ㅠ') , 'ㅓ' collection sequence ('ㅓ', 'ㅕ'), 'ㅏ' collection series ('ㅏ', 'ㅑ'), but place the 'ㅣ' collection series (button 8) Place the vowel button at (button 5, 7, 9, 0). 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.

As shown in Table 1, the vowel cross-shaped batch Hangul input device (Fig. 2: Patent Registration No. 10-0431733-00-00 'Hangul input processing device suitable for a mobile communication device using a reduced keypad' And the method '), it is confirmed that 10 strokes are required to input a short sentence, 24 at-bats are required to input a Chinese sentence, and 48 at-bats are required to input a long sentence. The vowel crisscross type Hangul input device uses a multi-tap method for inputting consonants, a two-key method for inputting multiple 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 the corresponding vowels on each of the five buttons, fourteen consonants are placed on the remaining five buttons. Since the consonants are arranged in the button is arranged two to three consonants have a disadvantage that a large number of strokes are required during consonant input.

Therefore, the Hangul consonants and vowels are effectively placed on a limited button, and the Hangul input device is required to reduce the number of strokes required for inputting syllables compared to the prior art while shortening the time required for the user to be familiar.

The present invention is to solve the problems of the prior art, it is applied to a product including a 3 × 4 keypad including 10 buttons arranged 0 to 9 and two buttons arranged '*' and '#' Hangul input device, which has '*' and '#' buttons, five consonant buttons with consonants only, one vowel button with only vowels, and four consonants with consonants and vowels together An input unit including a button, a memory including a vowel font storage area and a consonant font storage area, and a syllable combining unit for importing a font corresponding to a phoneme received from the input unit from a memory, and combining the imported fonts to form a syllable; An object of the present invention is to provide a Hangul input device.

Hereinafter, the Hangul arrangement as shown in FIG. 3B is specified as a field electronic Hangul arrangement , which appears when combining the vowels arranged in the Jamo mixture button.

However, the method for arranging the consonant button, the vowel button, and the button for mixing the Hangul on the 3 × 4 keypad can be various ways, and it can be included in the present invention as long as it does not violate the technical idea of the present invention.

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 ',' ㅐ ',' ㅒ ',' ㅔ ',' ㅖ ',' ㅘ ',' ㅙ ',' ㅚ ',' ㅝ ',' ㅞ ',' ㅟ ',' ㅢ ' Stores fonts for 21 vowels in Korean. In addition, the consonant font storage area 'a', 'b', 'ㄷ', 'ㄹ', 'ㅁ', 'ㅂ', ' ㅅ, ㅇ, ,, ㅊ, ㅋ, ㅌ, ㅍ, ㅎ, ', ㄸ, ㅃ, ㅆ, ㅉ Korean, including 'ㄳ', 'ㄺ', 'ㄻ', 'ㄼ', 'ㄽ', 'ㄾ', 'ㄿ', 'ㅀ' and 'ㅄ' Stores fonts for 28 consonants.

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, it serves to transmit the syllables formed by combining the plurality of phonemes to the display unit.

When the consonant button is pressed at the input unit, the syllable combiner retrieves the consonant arranged in the consonant button from the consonant font storage area of the memory. As described above, three consonants are arranged in the consonant button, and fonts to be loaded from the memory vary according to the number of times the consonant button is pressed. In other words, 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 second consonant placed on the consonant button. When the consonant button is pressed three times, a font for the double consonants ('ㄲ', 'ㄸ', 'ㅃ', 'ㅆ', 'ㅉ') arranged in the consonant button is called.

For example, the syllable combination unit reads the font for 'ㄷ' from the consonant font storage area by pressing the 'ㄷ ㄹ' consonant button once, and presses twice for the 'ㄹ' consonant button. The font 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, by pressing the consonant button three times, a multi-tap method and a consonant button for reading a font for the consonant arranged on the consonant button After pressing once, by pressing a special button to perform a consonant conversion is characterized by using a two-key method to read the font for the double consonants arranged in the consonant button. Conventionally, either a multi-tap method or a two-key method is used to input a twin consonant, so that 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 Tuki method can be used in a mixed manner, the user can be used in a method already 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, so the user 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 once the vowel button is pressed, the font for 'ㅣ' is pressed twice, and the font for 'ㅡ' is pressed three times. Press to read the font for 'ㅢ' from the collection 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 to read the font for the 'ㅢ' three times by pressing the vowel button and the vowel button once and then press a special button to perform the function of the double consonant conversion for the 'ㅢ' You can use a combination of two-key methods for reading fonts.

In addition, the syllable combining unit is loaded from the memory first from the component phonemes necessary for configuring the syllable according to the input value before the Jamo mixture button is input.

Hangul syllables consist of consonants, neutrals and species. The primary and final star are formed by consonants, and the neutral is composed of 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 in which the consonants and vowels of the buttons are mixed according to the conditions before inputting the buttons. However, in a special case, it may be possible to input contents that do not correspond to the Hangul spelling. The syllable combining unit reads fonts corresponding to the phonemes input by the Jamo mixed material button according to the alphabetical order as well as the Hangul spelling from the memory.

Referring to the 'TT ㅌ' alphabet mixed material button of the crisscross Hangul batch (Fig. 3a) as an example, if 'ㅋ' was input before pressing the 'TT 자' alphabet mixed material button, the 'ㅋ' is consonant, so the consonant Or it can be judged as finality. 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' letter combination button once to bring up the font for 'TT' and press the font for 'ㅠ' twice 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' letter combination button three times.

If 'ㄱ' and 'ㅏ' were sequentially input before receiving the 'TT ㅌ' letter mixture, the 'ㅏ' 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' letter combination button once, pressing the font for 'TT' twice, and pressing the font for 'ㅠ' three times. Read from the collection font storage area.
