Description

Korean input device {SYSTEM FOR INPUTTING KOREAN CHARACTERS FOR THE ELECTRONIC APPARATUSES}

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 final consonant of a Korean syllable, which are two-dimensionally arranged and composed of a 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 by simply floating between the phoneme order and the space. However, in the case of Hangeul, not only two-dimensional arrangement, but also when two or more consonants are repeated except Yieun (ㅇ), as in the example of "weave," "gyegi", "kigi" You need to decide how to place each syllable, and because more than 14 consonants and theoretically infinite vowels can exist, more complex protocols are required.

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). Later on, vowels were developed and settled by extracting the basic morphemes of each vowel, placing ━, ㆍ, and 에 on three buttons and entering all vowels through their permutations. Republic of Korea Patent Publication No. 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. If the input device is available and there is more than one consonant (and thus in most cases) between neutral and neutral (ie between vowels and vowels), then the user has a separate function key (e.g. There is a limit that you can decide the syllable you want by pressing the cursor movement key).

Summary of the Invention

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, the user automatically determines the arrangement for two or more consecutive consonants An object of the present invention is to provide a device for inputting Hangul in the same manner as writing with a pen.

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. .

The present invention for achieving the above object relates to a Hangul input device having a Hangul input unit, a database unit and a syllable determination unit as essential components.

The Hangul input unit includes the first to third keys allocated to the three basic shapes extracted by separating the morphemes of the Hangul consonants and the fourth to the third assigned to the three basic shapes extracted by separating the morphemes from the Korean vowels. A neutral input key consisting of six keys, a final input key consisting of seventh to ninth keys assigned the same figure as the first to third keys, and an tenth input key assigned to Yieun, a Korean consonant, to the tenth key. It is configured including keyboard or keypad. 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.

The database unit may be configured to recognize a response coded by a sequence of information for recognizing the input signal by the response input key as a Hangul consonant response and the input signal by the initial input key or the final input key. Each Hangul consonant information excluding and each Hangul vowel information coded by the permutation of the input signal by the neutral input key are stored. The database unit may be physically RAM or ROM.

The syllable determination unit receives a signal from the Hangul input unit, queries the database unit, and extracts consonants and vowels corresponding to the input signal to complete Hangul syllables. Specifically, (a) one or two or more signals are input from the initial input key or the response input key of the Hangul input unit, followed by one or more signals from the neutral input key of the Korean input unit, or (b) the Korean input unit. One or more signals from the initial input key or the response input key, one or more signals from the neutral input key of the Hangul input unit, and one or more signals from the final input key or the response input key of the Hangul input unit. After receiving, the database unit is queried to extract consonants and vowels corresponding to the input signal, thereby completing Korean syllables consisting of (a) primary and neutral or (b) primary, neutral and final. The syllable determination unit may be interpreted as a program that functions as electricity.

The syllable determination unit (A) when the neutral input key signal is input after the initial input key signal is input, extracts a consonant corresponding to the input first input key signal up to that point, and determines the initial consonant, and then the neutral input key signal is input. After inputting the initial input key signal, the vowel corresponding to the input neutral input key signal is extracted and determined as neutral to complete one Hangul syllable consisting of initial and neutral, and recently inputted initial input key. The signal is used as a signal for the beginning of the next Hangul syllable.

(B) When the neutral input key signal is input after the initial input key signal is input, the consonant corresponding to the input first input key signal is extracted to determine the initial consonant, and the final input after the neutral input key signal is input. When the key signal is input, the vowel corresponding to the neutral input key signal inputted until the previous time is extracted and determined to be neutral, and the consonant corresponding to the final input key signal input until immediately before the next initial input key signal is inputted is extracted. Completion of one Hangul syllable consisting of the first consonant, the neutral, and the final consonant, and the recently input first input key signal is used as a signal for the first consonant of the next Hangul syllable.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. The drawings or embodiments are merely examples of the apparatus to which the present invention is applied. ① Three basic morphemes of Korean consonants and Korean vowels are utilized, and ② three initial input keys, one final input key and neutral input, and one response. (ㅇ) Various embodiments may be possible based on the principle that the input key is a Korean input device installed basically.

3 is a schematic structural diagram of a Hangul input device according to the present invention. As shown in the figure, the apparatus according to the present invention basically comprises a Hangul input unit consisting of an initial input key, a neutral input key, a final input key, and a response input key, and a consonant or a vowel corresponding to a permutation of each input key. A syllable determination unit receives a signal from a database unit and a Hangul input unit that stores information, and extracts consonants and vowels corresponding to the input signal by querying the database unit. If necessary, a device for temporarily storing the completed Hangul syllables or a device for displaying the Hangul syllables confirmation process may be added to the Hangul input device according to the present invention.

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 syllable determination 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 the Korean consonants, ie, primary and final forms, are selected as ,, ∧, ┃, and vowels, ie, the basic shapes for neutral are ,, ㆍ, ┃. Each of them is placed on a keyboard or keypad equipped with at least 10 keys.The three keys on the first line are designated as the initial input keys to match the order of writing Hangul syllables. It is preferable to designate the Korean input consonant basic figure by setting the neutral input key, and to set the Korean consonant basic figure by setting the three keys of the third row as the final input key, respectively, and to place the corresponding input key on the last tenth key. 4).

Phonemes (consonants or vowels) corresponding to the input signal permutation of each of the initial, neutral, and final input keys input from 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.

On the other hand, in Hangeul is a consonant with no phonetic consonants, so its characteristics can be applied to the apparatus of the present invention. That is, when the first input signal is generated from the neutral input key or the neutral input key signal is generated immediately after the final input key signal, the syllable determination unit responds immediately before the neutral input key signal. ㅇ) Input key signal can be automatically processed as input. This can significantly reduce the number of strokes.

In the case of the Hangul input device according to the present invention, an abnormal situation, for example, the initial input key is continuously inputted so that the initial consonant cannot be determined, a key signal other than a predetermined permutation is input, or the final input immediately after the initial input key. It would be possible to add a system that would warn the user in the event of a key signal or the like and prompt for proper use.

5A, 5B and 5C are flowcharts illustrating a process of inputting Korean characters in the Korean input device according to the present invention.

For convenience of explanation, it is 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.

Since the first signal inputted from the input key of the Hangul input unit is the initial input key signal, the first signal starts to be stored in permutation as a signal for determining the initial consonant of the n-th syllable. When the initial input key signal is continuously input, the syllable determination unit stores the signal in permutation, and when the neutral input key signal is generated, it determines the initial consonant of the n-th syllable for the permutation of the initial input key signal. Delete the primary input key signal sequence. Meanwhile, the first inputted neutral input key signal is sequentially stored as a signal for neutral determination of the n-th syllable.

If the neutral input key signal is continuously input, the syllable determination unit stores the signal in a permutation sequence, and when the final or initial input key signal occurs, the syllable determination unit determines the neutral consonant of the n-th syllable for the permutation of the neutral input key signal up to this point. Delete the neutral input key sequence. ① When the initial input key signal is generated after the neutral input key signal, the syllable determination unit determines the n-th syllable composed of the initial-neutral. On the other hand, the first input first input key signal is first stored in a permutation store as a signal for the initial determination of the (n + 1) -th syllable. ② When the final input key signal is generated after the neutral input key signal, the syllable determination unit stores the final input key signal in permutation until the initial input key signal is input, and when the initial input key signal is generated, the final input key up to this time The stored final input key signal sequence is deleted while determining the final consonant of the n-th syllable for the signal sequence. The syllable determination unit then determines the n-th syllable consisting of the primary-neutral-terminus. On the other hand, the first input first input key signal is first stored in a permutation store as a signal for the initial determination of the (n + 1) -th syllable.

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 primary input keys and a final input key. And at least ten keys, such as a neutral input and one response input key. Therefore, the user can conveniently input the Hangul in the same order as the handwritting method without the need for special conscious memorization. In addition, since all Korean characters can be input with a limited number of keys, it is expected to be applied as a small keyboard or keypad to miniaturized and multifunctional electronic devices such as mobile phones.
