10: keypad 20: character code generation unit

The present invention relates to a Hangul input device, and more particularly to a Hangul input device using a small keypad.

One of the most common Hangul input devices is the keyboard, which is the basic consonant phoneme of Hangul: ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ , ㅋ, ㅋ, ㅌ, ㅍ, ㅎ, basic vowel phoneme ㅏ, ㅑ, ㅓ, ,, ㅗ, ㅛ Separate keys for "TT", "ㅠ", "ㅡ", "ㅣ" are to be assigned and input, and the consonant sound is inputted by the combination of the shift key and the corresponding consonant key. Double vowels and Hangul character combinations are supported by software called Hangul Autometa.

However, mobile terminals such as mobile phones and PDAs cannot be provided with the same level of keys as keyboards, and thus Korean characters can be inputted using 12 numeric keys (except function keys). However, as the size of the mobile terminal becomes smaller and smaller with the development of technology, the size of the keypad provided in the mobile terminal is smaller and the size of each key is also very small. The general public can enter characters freely even with such a small sized key, but in the case of a disabled person whose body motion is not smooth, it is very difficult to select and press a small sized key.

The use of all 12 numeric keys for character input in a conventional mobile terminal is intended for a general person who can operate normally and can be said to reduce the number of key strokes for character input as much as possible. However, in the case of a handicapped or disabled child whose physical motion is inconvenient, a keypad with a small size but a large size is more useful than a keypad with a large number of keys. Hangul input device that can input the can be said to be required.

The present invention was devised to solve the above problems, and the user uses a keypad having five keys which do not separately distinguish keys for consonant input and keys for vowel input. And a Hangul input device using the small keypad that can input Hangul by sequentially stroked key sequences assigned by stroke order, and a method thereof.

In order to achieve the above objects, the Hangul input device using the small keypad according to the present invention has a "＿" key (下地 key) disposed above and centered on the "*" key (天 key). A keypad on which a "￣" key is arranged, a "|" key is arranged on its left side, and a "|" key is arranged on its right side; And "a", "b", "c", "r", "ㅁ", "ㅂ", "ㅅ", "ㅇ", "ㅈ", "ㅊ", "ㅋ", "ㅌ", " For the Korean consonant phonemes of 」and ㅎ, the above five keys are combined independently according to the shape and stroke order of each phoneme, but a key array ending with a key other than the" · "key is assigned. A character code generator for generating a corresponding Hangul character code by combining the recognized phonemes when the key arrays are independently assigned to correspond to the shape and stroke order of the phonemes, and the key arrays are input; It is configured by.

In order to achieve the above another object, the Hangul input method using the small keypad according to the present invention includes (a) placing the "＿" key (下地 key) on the top of the "*" key (天 key) on the keypad. To place the "￣" key on the lower side, the "|" key to the left side, and the "|" key to the right side. step; (b) "a", "b", "c", "r", "ㅁ", "ㅂ", "ㅅ", "ㅇ", "ㅈ", "ㅊ", "ㅋ", "ㅌ" For the Korean consonant phonemes of ',' and 'ㅎ', the five keys are combined independently according to the shape and stroke order of each phoneme, and a key array ending with a key other than the '·' key is assigned. Assigning a key arrangement that independently combines the five keys corresponding to the shape and stroke order of each phoneme; (c) receiving key arrays and recognizing a corresponding Hangul alphabet whenever a key array assigned in step (b) is formed; And (d) generating the Hangul character code by combining the recognized phonemes by the Hangul autometa.

Hereinafter, preferred embodiments of the Hangul input device using the small keypad according to the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, a preferred embodiment of a Hangul input device using a small keypad according to the present invention includes a keypad 10 and a Hangul code generation unit 20.

Five keys are arranged in the keypad 10, centering on the "*" key (天 key) 12, the "＿" key (下地 key) 11 is arranged above, and the "」 "key below. Key 13 is placed, the "|" key 14 is placed on its left side, and the "|" key 15 is placed on its right side. do. In addition, the "11" key 11, the "*" key 12, the "￣" key 13, the "|" key 14, and the "|" key 15 are the numbers "1" and "2", respectively. "," 3 "," 4 "," 5 "are allocated in duplicate. The five keys disposed on the keypad 10 are preferably arranged to have a sufficient size and space so that the handicapped or a child can easily operate, but the specific size and space thereof are not limited in the present invention and are a choice of the developer. Therefore, further description thereof will be omitted. In the present embodiment, the keypad 10 has five keys for inputting a consonant / vowel phoneme of Korean. In principle, the keypad 10 further includes one or more separate function keys (not shown) for function expansion. It should be construed as not limiting it.

In addition, the keypad 10 in this specification is not only a keypad integrally provided in a mobile terminal such as a mobile phone, a PDA, etc., but also a user of an independent type keypad and a touch screen type input device used as an input device of a children's device. It is used in a broad sense including interfaces.

The character code generation unit 20 receives key arrays according to key strokes from the keypad 10, interprets the input key arrays, recognizes corresponding Hangul consonants / vowels, and combines the recognized phonemes. Generate a character code.

Basic consonant Key array Basic consonant Key array A 1,5 ㅇ 1,4,3,5 N 4,3 ㅈ 4,5,3 C 1,4,3 H 2,4,5,3 D 1,5,4,3 Lol 2,1,5 M 4,1,5,3 ㅌ 2,1,4,3 or 1,4,2,3 ㅂ 4,5,1,3 ㅍ 1,4,5,3 or 1,3 S 1,4,5 ㅎ 2,1 or 2,1,4,3,5

In order to recognize the corresponding Hangul consonant phonemes by the input key arrangement, the character code generation unit 20 manages a table as illustrated in Table 1. The numbers in the key arrangement of Table 1 represent the numbers displayed on each key, and mean the corresponding keys.

The key arrangement of the Hangul consonant phonemes shown in Table 1 is basically a combination of the five keys independently corresponding to the shape and stroke order of each phoneme. For example, "a" is formed by the stroke of the "key" key 11 in the stroke order, followed by the stroke of the "|" key 15, and "b" is the stroke of the "|" key 14 in the stroke order. After being stroked, the "￣" key 13 is formed by the stroke, and "c" is formed by the stroke order of the "＿" key 11 and the "|" key 14 is stroked, followed by the "￣" key 13 ) Is formed by stroke. Thus, the key arrangement of Table 1 is composed of combinations corresponding to Hangul consonant writing, so even beginners can easily recognize it with a little practice.

According to Table 1, all the key constellations of Hangul consonants are terminated with keys other than the "2" key (or "·" key) 12, which is confusing when used with the key constellations of Hangul vowel letters described below. It is configured not to.

In one embodiment of the present invention, the character code generation unit 20 is the last key input in the key array corresponding to "a", "c", "ㅂ", "ㅅ", "ㅈ" of the Hangul consonant phoneme When it is detected that the long press (for example, 0.5 seconds or more), the input consonants are recognized as twin consonants "ㄲ", "ㄸ", "ㅃ", "ㅆ", and "ㅉ". However, in another embodiment, the keypad is provided with a function key for inputting a consonant, and the character code generator corresponds to "a", "c", "ㅂ", "ㅅ", and "ㅈ" among Korean consonants. If the consonant function key is input immediately after the key arrangement is input, the consonant inputted first may be recognized as the twin consonants "ㄲ", "ㄸ", "ㅃ", "ㅆ", and "ㅉ".

Basic vowel Key array Basic vowel Key array ㅏ 4,2 ㅛ 2,2,3 ㅑ 4,2,2 TT 1,2 ㅓ 2,5 ㅠ 1,2,2 ㅕ 2,2,5 ㅡ 3 ㅗ 2,3 ㅣ 5

In order to recognize the corresponding Hangul vowel characters by the input key arrangement, the character code generation unit 20 manages a table as illustrated in Table 2.

In the present embodiment, the vowel input method is similar to the celestial input method, but the land key according to the prior art is divided into a "key" key 11 and a "kkey" key 13. In the related art, the human key is divided into "|" key (右 人 key) 14 and "|" key (左 人 key) (15), and keys for vowel input as they are. It is to use as. Double vowels such as ㅐ, ㅒ, ㅔ, ㅖ, ㅘ, ㅙ, ㅚ, ㅝ, ㅞ, ㅟ, ㅢ Can be combined by extending the key array. For example, the key sequence for "ㅖ" is 2,2,5,5.

On the other hand, the character code generation unit 20 may manage the numeric input mode in addition to the character input mode. The character code generation unit 20 may switch between the character input mode and the numeric input mode by detecting a stroke of a separate function key or by detecting a long press of the "|" key (右 人 key) 14. Utilizing the "|" key 14 to toggle between the character input mode and the number input mode is that the "|" key 14 (i.e., numbers) among the key arrangements corresponding to the consonant / vowel consonants of Table 1 and Table 2. This is possible because there is no key sequence ending with "4" key).

In an exemplary embodiment of the present invention, the character code generation unit 20 may enter “1” when the keys marked “1”, “2”, “3”, “4”, and “5” are shortly input in the numeric input mode. , '2', '3', '4', '5' character codes are generated, and in the numeric input mode, the keys marked '1', '2', '3', '4', '5' are short. If input twice, it is implemented to generate "6", "7", "8", "9", and "0" character codes, respectively.

However, in another embodiment, the character code generation unit 20 assigns one or two simultaneously pressed key combinations to the numbers "0" to "9", respectively, and the numeric keys input in the numeric input mode or the simultaneously pressed numeric keys. It may be implemented to generate a numeric code corresponding to the combination of. For example, the key combinations illustrated in Table 3 are possible.

number Key combination number Key combination One One 6 4 + 3 2 2 7 5 + 1 3 3 8 5 + 2 4 4 + 1 9 5 + 3 5 4 + 2 0 2 + ANY KEY

Also, according to Table 1, 1,4,3,5 key arrays are assigned to the Korean consonant phoneme "ㅇ". 4 key strokes is very burdensome. To this end, the character code generation unit 20 does not input a key array corresponding to "ㅇ" in the initial letter of the first letter for each word when the Hangul character is input. It is desirable to recognize that the initial property of is "o".

Hereinafter, a Hangul input method using a small keypad according to the present invention will be described with reference to FIG. 2.

First, the "10" key is placed on the keypad 10 with the "*" key (天 key) 12 as the center, and the "￣" key (上 地) below it. Key) 13, the "|" key 14 is arranged on the left side, and the "|" key 15 is arranged on the right side (S10). In addition, the "11" key 11, the "*" key 12, the "￣" key 13, the "|" key 14, and the "|" key 15 are the numbers "1" and "2", respectively. "," 3 "," 4 "," 5 "are allocated in duplicate. In addition, the keypad 10 is provided with the above five keys for inputting the Korean consonant / vowel phoneme, but one or more separate function keys may be installed to expand the function.

In the character code generation unit 20, "a", "b", "c", "r", "ㅁ", "ㅂ", "ㅅ", "o", "ㅈ", "ㅊ", "ㅋ" For the Korean consonant phonemes of ,, ㅌ, ㅍ, and ㅎ, the above five keys are combined independently according to the shape and stroke order of each phoneme. For the Korean vowel phoneme, a key arrangement in which the above five keys are independently combined in correspondence with the shape and stroke order of each phoneme is allocated (S20).

Thereafter, the character code generation unit 20 detects key arrangements input by the user (S30), and recognizes a corresponding Hangul alphabet whenever a pre-assigned key arrangement is formed (S40). Thereafter, the Hangul character code is generated by combining the recognized phonemes by the Hangul autometa (S50). At this time, it is detected that the last key input is pressed for a long time (for example, 0.5 seconds or longer) in a key array corresponding to "a", "c", "ㅂ", "ㅅ", and "ㅈ" among Hangul consonants. In this case, the input consonants are recognized as double consonants "ㄲ", "ㄸ", "ㅃ", "ㅆ", and "ㅉ".

Assume that the key array entered by the user is as follows.

"1, 5, 4, 2, 4, 1, 5, 3, 1, 4, 5, 4, 2, 2, 1, 4, 2, 4, 5, 1, 3, 4, 3, 5, 1 , 4, 3, 4, 2 "

First, a key array of "1, 5" is inputted to recognize "AB", a key array of "4, 2" is inputted to recognize "ㅏ", and a key array of "4, 1, 5, 3" By inputting this and recognizing "wh", the Hangul autometa of the character code generation unit 20 generates a character code of "sensation".

」이란 문자 코드를 생성한다.Subsequently, a key array of "1, 4, 5" is input to recognize "S", a key array of "4, 2" is input, to recognize "ㅏ", and a key array of "2, 1" is input. By recognizing "ㅎ", the Hangul autometa of the character code generation unit 20 is "

Generates a character code.

」 대신에 「사」란 문자 코드를 생성하고, 그 다음으로 입력된 키 배열 "4, 5, 1, 3"를 「ㅂ」으로 인식함으로써, 「합」이란 문자 코드를 생성한다.By the way, since the key array input afterwards is the neutral "ㅏ" of "4, 2", the Hangul autometa "

Instead of "," 4 "is generated, and the next input key array" 4, 5, 1, 3 "is recognized as" ㅂ ", thereby generating a character code of" sum ".

」이란 문자 코드를 생성한다. Subsequently, a key array of "4, 3" is input to recognize "b", a key array of "5" is input to recognize "ㅣ", and a key array of "1, 4, 3" is inputted. By recognizing "c", the Hangul autometa of the character code generation unit 20 is "

Generates a character code.

」 대신에 「니」와 「다」란 문자 코드를 생성한다.Afterwards, the input key array is the neutral "ㅏ" of "4, 2".

Instead of ", generate the" y "and" da "character codes.

Therefore, the character code "Thank you" is input as a whole.

So far I looked at the center of the preferred embodiment for the present invention. Those skilled in the art will appreciate that the present invention can be implemented in a modified form without departing from the essential features of the present invention. Therefore, the disclosed embodiments should be considered in descriptive sense only and not for purposes of limitation. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the scope will be construed as being included in the present invention.

According to the present invention, each key is relatively wide in spite of being a small mobile terminal by inputting Korean characters using a keypad having five keys which do not separate keys for consonant input and keys for vowel input separately. It is easy to input Hangul while handicapped people or children with space. Therefore, the Hangul input device of the present invention can be utilized in information terminals that deaf people can communicate with each other through the input of Hangul characters and display confirmation.

In addition, according to the present invention, since the key arrangements respectively assigned to the Hangul alphabet / vowel phoneme are based on the shape and stroke order of writing the corresponding phoneme, even beginners can easily learn. Therefore, as the Hangul input device of the present invention is spread, the superiority of Hangul can be promoted naturally.

In addition, as the present invention is activated on the existing mobile terminal keypad, it is possible to use the extra keys for additional purposes such as the Internet, electronic payment, etc., and when using them for children's play equipment, it becomes possible to learn Korean characters naturally. .
