Description

Korean input device {APPARATUS FOR INPUTTING KOREAN LETTERS}

The present invention relates to a Hangul input device, and more particularly, to a Hangul input device that can be applied to a variety of electronic devices, including personal computers, in particular mobile phones, etc., the number of buttons (keys) to be mounted according to the miniaturization of the device. .

Hangul is the initial consonant of a Korean syllable unlike a phoneme, that is, English, French, German, and Japanese except for Hanja, where each alphabet is arranged one-dimensionally (ie in a row). , A vowels of a Korean syllable, and a finality (the final consonant of a Korean syllable). Have a system.

In the case of inputting a character into an electronic device, a one-dimensional character is possible only by a relatively simple character input protocol because a single word is completed only by phoneme order and space. However, in the case of Hangul, not only two-dimensional arrangement, but also when two or more consonants are repeated except Yi Eung ( ㅇ ), as in the example of lace, weight, and female, how should they be arranged in each syllable? More complex protocols are required because there are basically 14 consonants and theoretically infinite vowels.

With the rapid development of electric and electronic technology, various electronic devices such as mobile phones, PDAs, pagers, small game machines, remote controllers, cameras, home appliances, etc., such as CDMA, PCS, TDMA, GSM, AMPS, IMT-2000, etc. It is being advanced. However, as the function is improved in inverse proportion to the miniaturization, as the desire to express characters in electronic devices increases, the necessity of inputting characters continues to increase. In response to this, various methods (devices) for inputting Korean characters have been developed, particularly in mobile phones with limited buttons (keys). The initial input device is the simplest. When the Hangul input mode is displayed, all consonants (consonants) are displayed on the LCD (display device), the user selects the desired consonant using the cursor, and when a large number of vowels are displayed, the user One syllable was determined by moving a cursor to select a desired vowel (Korean Patent No. 99-24320). Since then, the vowel input method (device), the so-called Cheonji, was developed and settled by extracting the basic morphemes of each vowel, placing ━, ·, and 에 on three buttons and entering all vowels through their permutations. Patent 97-2558).

Consonant input method (device) is largely: ① A method of determining one consonant according to the number of presses of a specific key within a predetermined time by arranging two or three consonants (continuously arranged), ② Only one consonant that is the core is placed on one key, and 2 or 3 function keys are added to the consonant that is not arranged on the key. To select consonants by pressing (function key utilization type) and ③ morphologically disassemble each consonant, extract shapes (or symbols) that are common in shape, place them on each key, and press these keys one to several times By the method of selecting consonants (figure permutation type).

Continuous batch type is disclosed in Korean Patent Publication Nos. 00-18394 and 00-41317. According to the above data, one consonant or vowel corresponding to the number of times a particular key is pressed is sequentially selected to complete one syllable in a keyboard composed of a total of 8 or 11 keys in which the consonants and vowels are assigned in sequence or arbitrarily two or three. It is done. However, this method is not easy to use because many phonemes are printed on one key, which not only confuses the user, but also keeps an eye on the change of phonemes displayed on the display device according to key presses. There is this.

The function key utilization type is disclosed in Korean Patent Publication Nos. 00-42231, 00-49346, 00-49347 and 00-54571. The technique of these materials allocates 6 to 7 representative consonants to one key, arranges the three vowel morphemes or 6 representative vowels to 5 to 6 keys, and 1 to 3 function keys. The keyboard where I placed is applied. The phoneme not displayed on the key is determined by selecting a predetermined phoneme displayed on the key and pressing a predetermined function key a predetermined number of times within a predetermined time. Although this method has the advantage that the keyboard is visually clean, it takes a lot of effort and time to quickly and freely select phonemes not displayed on the keys.

An example of a graphics sequence Hangul input method approached under a different concept from the continuous arrangement type and function key utilization type is disclosed in Korean Patent Publication No. 00-17771. Fig. 1 shows the key arrangement in the data, and Fig. 2 shows the correspondence between the permutations of the keys and the phonemes. In order to determine one phoneme by two key inputs, the disclosed patent invention abstracts a common figure extracted by dismantling consonants so much that the relationship between the permutations of the figures and the corresponding phonemes must be memorized clearly. is able to use an input device, and if any abnormality is consonant than two yieung (o) to (among other words collection and collection) neutral and neutral between (and thus in most cases) that a separate function key (e. g. There is a limit that you can decide the syllable you want by pressing the cursor movement key).

The present invention is to solve the problems of the conventional Hangul input method (device) mentioned above, the user does not need to specifically memorize consciously, by determining the arrangement automatically or manually for two or more consecutive consonants An object of the present invention is to provide a device capable of inputting Hangul in the same manner as a handwriting by a user.

6 is a flowchart illustrating a process of artificially separating the final and the first consonants in the Hangul input device according to the present invention.

The present invention for achieving the above object relates to a Hangul input device including a Hangul input unit, a database unit, a phoneme extraction unit and a syllable determination unit.

The Hangul input unit includes a consonant input key consisting of first to third keys allocated with three basic shapes extracted by separating the shapes of the Hangul consonants, and fourth to fifth allocated three basic shapes extracted by separating the shapes of the Korean consonants. and 6 the key bar, the input key comprising, an input device, such as Hangul consonants of yieung (o) is configured including the dividend yieung input key keyboard, a keypad or a touch screen. Of course, additional special function keys (for example, a mobile phone, for example, a signal transmission key, call interruption key, and various menu keys) required for an electronic device may be added thereto. In addition, if necessary, a Hangul-number-English conversion key and a special character input key may be added.

A database unit, the coding information corresponding to the input signal by the yieung input key corresponding to the permutations of the input signal according to the information, the consonant input key to be recognized in Hangul consonants yieung (o) coding, except yieung (o) It is a searchable information group that stores each Hangul consonant information and each Hangul vowel information coded corresponding to a permutation of input signals by a vowel input key. The database unit is physically stored in a storage device such as RAM or ROM.

The phoneme extracting unit receives one or more signals from the consonant input key, the response input key, and the vowel input key of the Hangul input unit respectively, and then extracts the consonants and vowels corresponding to the permutation of the input signal by querying the database unit. Do it. The phoneme extracting unit may be a kind of program.

The syllable determination unit is a device that completes Hangul syllables by combining consonants and vowels extracted by the phoneme extractor.

The syllable decision unit, ① vowels and the number of consonants that can exist between 1 to 4 consonants, ② the first consonant consists of 1-2 consonants, ③ the final consonant consists of 0 to 2 consonants, ④ consonants in the consonant If the number is 2, the consonants are always the same. ⑤ If the consonant Yi-eun ( ㅇ ) comes to the initial consonant, there is no phonetic value. ⑥ The consonant-yiung ( ㅇ ) cannot be between the consonant and the consonant. Hangul syllables are determined from phonemes of vowels.

That is, the syllable determining unit (A) if the number of consonants between the vowel extracted by the phoneme extracting unit and the vowel is 1, determines the consonant as a consonant of the next syllable, and (B) the vowel extracted by the phoneme extracting unit. If the number of consonants between and vowels is 2 or 3 and the two consonants are different, the final consonant is determined as the beginning of the next syllable and the final consonant is the final syllable, and (C) the vowel extracted by the phoneme extraction unit. If the number of consonants between and vowels is 4, it is preferable that the two consonants and the second consonant are programmed to determine the final syllable and the first syllable of the next syllable, respectively.

On the other hand, as in the examples such as [chief, weights], [inverses, weaving], [dad, apaba], [god, gasso], [go, gatsaw], etc., in Korean, the number of consonants between vowels and vowels is 2 or 3 If two consonants are the same, there are cases where two syllables are possible by the same phoneme sequence, and the syllable determining unit cannot operate correctly. Therefore, if the number of consonants between the vowels and the vowels is 2 or 3 and the two consonants in the future are expected to be the same according to the key input of the Hangul input unit-not the action of the syllable decision unit-artificially, that is, by the user's operation Alternatively, it is preferable to divide the consonant group into the final syllable of the first syllable and the first syllable of the next syllable by the user's non-operation.

According to the user's operation, the method is to add a sparse separation key to the Hangul input unit of the input device according to the present invention, and when the sparse separation key is input, the consonant extracted immediately before the extracted consonant is determined to be the final syllable of the last syllable, and then a new input. When the consonant is extracted by the key signal, the consonant is determined as the consonant of the next syllable.

Another method by the user's manipulation is to make the response input key perform the function without adding a separate parasitic separation key. That is, if after the extraction consonant yieung (o) is an extraction method of determining the front of the consonant yieung as trailing the preceding syllable, and then when a consonant is a consonant of the following syllable extracted determine and remove the yieung.

In the apparatus according to the present invention, in order to prevent confusion of the user, all the consonants may be applied so that the herbicidal separation method by the user's operation is applied.

The method of separating the seedlings by the user's non-operation is that after the consonant and the vowel have been extracted or after the consonant, the vowel and the consonant have been extracted and there is no additional key input signal for a predetermined time, the consonant and the vowel or the consonant, the vowel and It is to determine the syllables that make consonants consonant and distant, or consonant, neutral and distant. In this case, no additional key needs to be added.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. Figure or embodiment as a mere example of a device to which the invention is applied, ① Hangul consonants and Hangul collection basic morpheme and utilizing three individual, ② 3 consonants input key, neutral type, one yieung (o) the input key Various forms of the embodiment will be possible based on the principle that is basically an Hangul input device installed.

3 is a schematic structural diagram of a Hangul input device according to the present invention. As shown in the drawing, the apparatus according to the present invention basically includes a Hangul input unit consisting of a consonant input key, a vowel input key, and a response input key, and a database unit that stores information on consonants or vowels corresponding to a permutation of each input key. And a phoneme extracting unit for receiving a signal from the Hangul input unit, searching a database unit, and extracting consonants and vowels corresponding to the input signal, and a syllable determining unit combining the extracted phonemes to complete the Hangul syllables. In the apparatus of the present invention, there may be independently a control unit for controlling and adjusting the operation relationship of the respective components. If necessary, the Hangul input device according to the present invention may be added a temporary storage device for temporarily storing the completed Hangul syllables, a device for displaying the Hangul syllable confirmation process.

Each component of the Hangul input device according to the present invention is merely a functional division for the operation of the present invention, and they do not necessarily have to be physically independent. For example, it will be obvious that the database unit and the phoneme extracting unit may be manufactured as one integrated program or one component as necessary.

In addition, in the input device according to the present invention, additional input keys and input keys for additional functions such as input of special characters such as quotation marks, commas, periods, Korean-English-numeric input conversion, space bar function, etc. Adding functionality would be easy for one of ordinary skill in the art.

In the preferred embodiment of the present invention, the basic shapes of Korean consonants, that is, initial and final forms, were chosen as ━, ┃, ∧ , and vowels, that is, the basic shapes for neutrals were chosen as ━, ·, ┃. Each of them is placed on a keyboard, keypad, or touch screen equipped with at least seven keys.The three keys on the first line are defined as consonant input keys, and the basic Korean consonants and the three keys on the second line are vowel input keys. appointed it is preferred to place the respective Hangul yieung bar (o) input key a basic figure, the end seventh key (Fig. 4).

Phonemes (consonants or vowels) corresponding to each consonant, the input signal sequence of the vowel input key, and the response input key input signal inputted by the Hangul input unit illustrated in FIG. 4 may be determined as shown in Tables 1 and 2 below. In this case, the consonant and vowel coding information shown in Table 1 is stored in the database unit.

In the case of the Hangul input device according to the present invention, in an abnormal situation, for example, the consonant input key is continuously inputted so that the finality and the initiality cannot be determined, or a key signal sequence other than the permutation stored in the database is input. It would be possible to add a system that could alert the user to this and prompt the correct use.

5 is a flowchart showing a seed type automatic separation method in the Hangul input device according to the present invention.

As shown, if there is one consonant between the extracted vowel and the vowel (A), the consonant is determined as the consonant of the latter syllable, and if there are two consonants between the vowel and the vowel (B) and the two consonants are not equal, the front The consonant is determined as the final syllable of the previous syllable and the later consonant is the first syllable of the next syllable.

If there are three consonants between the vowels (C) and the last two consonants are not the same, the first two consonants are determined by the final syllable, the last consonant is the first syllable, and if the two consonants are the same, Artificially- or non-manipulated-herbicidal separation methods apply. If there are four consonants between the vowels (D), the first two consonants are determined to be the final syllables and the second two consonants are the first syllables.

FIG. 6 is a flowchart illustrating a process of artificially separating a seed and a starch that may be applied to the present invention when it is not possible to automatically separate seedlings or even when a plurality of consonants are extracted. For convenience of description, the description of the operation of the control unit for controlling and adjusting each component of the apparatus of the present invention is omitted. It is also assumed that there is no abnormal input. First of all, in order to start the input, the input device must be dedicated to Hangul or be switched to the Hangul input mode.

If there is a consonant input key signal after the vowel input key signal, the signal sequence is stored in the forest storage device, and the phoneme extractor checks the database unit to check whether there is a consonant corresponding to the stored signal sequence. If there is no corresponding consonant, the control unit continuously receives the consonant input key signal and stores the permutation, and the phoneme extracting unit checks the corresponding consonant. If there is a corresponding consonant, the consonant is extracted to determine the desired consonant, and the temporarily stored signal sequence is deleted (consonant determination step).

Then, if there is a consonant input key signal, the process is repeated while storing the permutation, and the secondary constellation separation key signal (signal of the response input key when using the response input key) or an additional consonant input key signal has elapsed for a predetermined time or more. In this case, the consonants determined in the previous process are determined as the final syllables of the preceding syllables (separation phase separation), and the subsequent consonants are determined as the initial consonants of the next syllable (consonant determination step).

By repeating the process as described above, syllables, words, sentences, and the like in Korean can be prepared.

As described in detail above, the Hangul input device according to the present invention extracts three basic morphemes of the Korean consonants and the Korean vowels, and determines consonants and vowels based on their permutations, respectively, three consonant input keys and a vowel input key. you can form at least seven keys such as one yieung (o) the input key. Therefore, all Korean characters can be input with a limited number of keys, so it is expected to be applied to small-sized and multifunctional electronic devices such as mobile phones as small keyboards, keypads, and touch screens. In addition, by extracting and using the morphemes of the Korean consonant vowels, the user can conveniently input the Korean characters in the same order as the handwriting method without the need for special conscious memorization.
