Description

A system and method for inputting character in a telephone}

The present invention relates to a character input method using a phone, and in particular, a phone that allows for easier and convenient input of Korean characters by automatically recognizing seconds, middle, and finality using a Hangul module executed by a Hangul recognition program. It relates to a character input method using.

Recently, the purpose of the telephone is not to be used only for a simple voice call, but to use various additional functions. Various functions such as a memory function using a text input and a text transmission function have been utilized. However, the keypad for inputting characters has to implement all desired characters by using numeric buttons ('1'-'9', '0') and special buttons ('*', '#') in the limited device structure of a telephone. do.

Various methods have been suggested for inputting Korean characters, and the menu method displays Korean alphabet characters on the screen and inputs them using a numeric code and the Korean alphabet characters on the keypad of the phone. There is a way to input Hangul by defining Korean combination and creation rule.

Currently widely used multi-frequency code (MFC) push-button telephones can store phone numbers in correspondence with Korean characters, and can input, transmit, and control characters between systems that can transmit and receive DTMF signals from MFC telephones. By arranging Korean alphabets and vowels on the 12 numeric buttons of MFC phones and defining the combinations and generation rules of characters, MFC phones are actively using existing phones as information terminals.

Wireless handset manufacturers, such as mobile phones, provide their users with their own text input systems. However, the utilization is low. The reason is that the provided character input system is complicated and difficult to use. Also, the dial button is pressed too many times to display the desired character.

The reason why the text input system currently used or provided is encountered in this problem is that it is necessary to implement text input with only 12 dial buttons. Implementing characters with limited dial buttons can be inconvenient for the way you already use them. In particular, this is more prominent in the implementation of Hangul than in the implementation of alphabets, special symbols, and numbers.

When implementing Hangul, in order to implement complex Hangul such as Bokja consonants, Bok vowels, etc., it is common to implement through a predefined "combination of dial button and * or # key".

However, this is inconvenient for the user to memorize this method. Or you can see how to write the entire consonants and vowels on the dial button and press the desired consonants and vowels (including the consonants and vowels) several times. This also shows the disadvantage of too many presses and problems such as rewriting.

The present invention is to provide a character input system and a method of the phone of the user to implement the character completely with only a limited number of buttons to solve this problem and at the same time easy and convenient to use the user.

Therefore, the present invention should firstly be extremely simple in its use. In other words, it should be easy, and secondly, the number of times the dial button should be pressed should not be high, and thirdly, the user may realize the desired character while satisfying the above two conditions.

The character input system of the present invention for achieving the above object is, first of all, the center of the Hangul implementation of the character input, there is no predefined combination key, any combination in marking the vowel sound, bokja consonants, vowel vowels, etc. There is no key, and you need to press the dial button a few times to implement the character, and to support the writing, you don't have to press any key as a sign that you have completed the Hangul characters. Any Korean characters can be written because it is composed of Bokja consonants, Bok consonants, and Bokja consonants ("ㄲ", "ㄹㅂ") and Bok consonants ("ㅐ", "ㅙ") are implemented by combining single consonants and single vowels. It is characterized in that it is made so as not to mark it separately on the dial button.

The present invention automatically recognizes whether the current input signal corresponds to consonants or vowels based on the Hangul structure composed of initial, neutral, and final characters, and the initial, It converts into neutral and final, and when the conversion key is input, the last input character is automatically converted into seconds, middle, and species by Hangul establishment, and when the delete function is deleted, the corresponding character is deleted and the conversion state is returned to the previous state. It is characterized by the implementation of Hangul input according to the apprentice principle of Hangul.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary view of a keypad of a Hangul input telephone according to the present invention. As shown in the drawing, consonants and vowels are arranged in correspondence with 12 telephone buttons ('1-0', '*', '#'). do.

As shown in FIG. 1, Korean characters and function keys are defined in 12 keys, and Korean characters are inputted according to Korean combination and generation rules. The characteristics of Hangul consonant and vowel arrangement are that the basic consonants are arranged in sequence for each key, and the vowels ('ㅋ', 'ㅌ', 'ㄷ', 'ㅊ') are arranged in plural to the corresponding basic consonant keys. The vowel placed only one single vowel for each key. In addition, double consonants (including consonants) can be implemented by a combination of consonants, a double vowel and a triple vowel by a combination of a single vowel. In other words, the first input is consonant and the second input is automatically recognized as a vowel according to the Hangul composition rules by placing ㅏ, ㅑ, ㅓ, ㅕ, ㅛ, ㅛ, ㅠ, ㅡ, ㅣ up to the number 1-0, respectively. It is an array characteristic for.

The relation between the Hangul consonants and vowels and the dial buttons corresponding thereto, the method of mapping the consonants and vowels to the dial buttons thoroughly considered the convenience of the user. Most people are aware of the consistent sequence of consonants and vowels unconsciously, and the consonants are familiar with the order "" ㄴㄹ ㅁㅂ ㅅㅇㅈ ". Buttons corresponding to "a" were followed by "ㅋ" and buttons corresponding to "c".

In the case of the vowel consonants and vowel vowels, as described above, the consonants and the vowels are embodied in combination with 14 consonants and 10 vowels including the above-mentioned vowels.

Therefore, this table was arranged in order to give the impression that the user is familiar and easy, and corresponded according to the order of consonants and vowels that are familiar to users, and the number of consonants and vowels that corresponded was small.

Problems that may arise from this (both consonants, implementations of consonants) are all handled automatically by the internal modules of the character input system.

2 is a block diagram of a text input system of a telephone according to the present invention.

An input unit 10 which recognizes and inputs a key signal input from the keypad; A character mode control module 20 for determining a character mode based on an input value through the input unit 10 and controlling to process a character input for each mode; Based on the character input mode control of the character mode control module 20, according to the state of the character input storage area of the mode, the character corresponding to the current input value is searched by a predetermined character input rule to process the character input. A buffer status recognition and indicating module 30; Under the control of the state of the buffer and the instruction module 30, the character corresponding to the input value is found in the character table so that the character combination is established and stored in the character storage area, and the character combination stored in the character storage area is completed as one character. A search and combination check module 40 which transmits the completed character to the sentence buffer, and informs the buffer state recognition and indicating module 30 of the text storage area when the text is completed; A character storage area (50) having respective character input buffers for each character mode and temporarily storing characters searched by the search and combination check module (40) until one character is completed; Korean consonants, vowels and Hangul complete type table corresponding to each key value of the keypad, English, numbers, special symbol table is provided to search for the corresponding character according to the input value, the character table for searching the character establishment ( 60); A sentence buffer 70 for completing the input sentence by additionally storing the completed character when the combination of characters stored in the character storage area 50 completes one character; A menu display of a text input mode under the control of the text mode control module 20 and an output for outputting a text stored in the sentence buffer 70 and a text stored in the text storage area 50 together to the display means LCD. It is comprised including the part 80.

Here, the character storage area 50, the English module is composed of one English input buffer, in the case of the Hangul module is provided with two buffers for the initial formation, three buffers for the neutral and two buffers for the final, In the case of a character module, one character input buffer is configured. In numeric module, since one number is corresponded to one key, conversion key is not needed. Therefore, it is recognized as a completed character and stored in sentence buffer. Korean, English and special characters duplicate the last input value. Use the character input buffer to convert to the displayed character.

The character table 60 includes an English uppercase letter and a lowercase table in the English module, the special character module includes a corresponding special character table, and the Korean module includes a Korean consonant, a vowel, and a complete type table.

3 is a detailed configuration diagram of the Hangul module according to the present invention, as shown in the text input buffer, the maximum combination of Hangul, that is, to achieve the structure of consonant + consonant + vowel + vowel + vowel + consonant + consonant To this end, the Hangul storage area 51 is configured by allocating two buffers at the beginning, three buffers at the neutral, and two buffers at the final.

The Hangul character table 61 is composed of a consonant table, a vowel table, and a Hangul complete table, and the consonant table is a general consonant (ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅎ) table. And, consonants (ㅋ, ㅌ, ,,)) table, double consonants (ㄲ, ㄸ, ㅆ, ㅉ, 과), 일반, ㄵ, ㄶ, ㄺ, ㄻ, ㄼ, .... A double consonant table is formed, and the vowel table includes a single vowel (ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, ,, ,, ㅡ, ㅣ) table, and a double vowel (ㅐ, ㅒ, ㅔ, ㅖ, ㅟ, ㅚ,., ..) table and triple vowel (ㅙ, ㅞ, ..) table, and the Hangul complete table is configured to provide all the Hangul that can be provided as a table.

The buffer state recognition and indication module 31 recognizes the buffer state of the initial, neutral, and final, and searches the consonants or vowels corresponding to the buffers of the super, medium, and final where the input value can be located by the buffer state. It is made to indicate.

The search and combination check module 41 includes a consonant search unit for searching for consonants or vowels indicated in the table in accordance with an input value, a vowel search unit, and a Hangul complete search unit for searching the combined Hangul. A buffer initialization unit for initializing a buffer, a transmission unit for transmitting a completed sentence to a sentence buffer, a conversion control unit for controlling conversion of the last input character into a corresponding character according to the state of the character input buffer, and deletion. It includes a delete control unit for controlling the, double consonants including double consonants of Hangul, double and triple vowels are configured to control the implementation of Hangul by combining according to the principles of Hangul disciples by a combination of a single consonant and a combination of a single vowel.

On the other hand, Figure 4 is for explaining the configuration and Hangul input method for the Hangul input buffer of the present invention.

Hangul is composed of consonants and consonants, and consonants + consonants, consonants + vowels + vowels, and consonants + consonants + consonants. In the neutral, three buffers B1 (B2) and B3 are assigned, and in the finality, two buffers C1 and C2 are allocated. When the user presses the dial button (numeric buttons) to input Korean characters using this type of Korean structure, the input values (characters) that are sequentially input are recognized first in the order of A1 → B1 → B2 → B3 → C1 → C2. It is assigned to the next order automatically determined by the Hangul combination rule, and determined in accordance with the Hangul combination rules, and automatically receives the input by judging the Hangul input value by the rules, such as conversion, deletion.

The present invention configured as described above controls the text input mode as shown in FIG. 5. FIG. 5 is a flowchart for controlling the text input mode according to the present invention.

When the text input mode is set for searching or sending a message using a phone, the mode is initialized to the Hangul mode by the mode initialization process (S1). In the state initialized to the Hangul mode, the input value is determined (S2), and the input value is determined as the character mode change (S3), the general character key input (S4), and the function key input (S5). If the character mode is changed, the character mode is changed to the corresponding mode among "Hangul", "Hanja consonants", "English", "number" and "special characters" according to the corresponding key input value (S6). In the change of the character mode, the input value determination according to the input rule and the character combination rule is applied differently according to the corresponding character mode, and the character input buffer on the character input storage area 50 is set differently. The buffer status recognition and indication module 30 and the search and combination check module 40 drive subprograms for each character therein. When the character mode is changed in this way, the character buffer of the previous mode in the character input storage area 50 is transferred to the sentence buffer 70 (S7) to be treated as sentence completion and the character input buffer according to the changed character mode is changed. Set it up and get ready to accept the new input. In addition to displaying the changed mode, the current input characters stored in the sentence buffer are output (S8), and a new key input is waited for.

On the other hand, in the case of the general character input key (S4), the input value is retrieved from the character table 60 according to the current character mode (S9), and the combination of the retrieved character and the character stored in the character input buffer on the character storage area 50 is used. The character combination is searched by searching for other characters corresponding to the same input value automatically according to a predetermined rule until it is established by searching whether the character is supported as the completed type character (S10). When the character combination is established, the search character is stored in the corresponding character input buffer of the storage area 50 (S11), and it is determined whether one character is completed (S12). (S13), if the character is completed or not yet completed, the contents of the mode sentence buffer and the character input buffer is displayed on the screen through the output unit 80 (S14) so that the user can check the displayed content.

When defining such a character input rule as a program and the present invention with the necessary character tables, the basic principle or concept will be described with reference to the following tables.

The present invention is composed of Korean consonants and vowels corresponding to dial button codes, English large (small) letters, and special symbols codes as shown in Tables 1, 2, 3, and 4, and has a control code for controlling them. The numbers should be recognized and used exactly as they are written on the dial button without any code.

In Table 3 above, only two of the special symbol handling problems are specified, but this may be a significant addition or correction in the future. Here, only two are specified for simplicity. The description of special symbols is no longer given.

If you press the character mode change key (# 9) in the above <Table 4>, you can select the currently supported character mode by LCD screen or voice.

For example, if you press the text mode change key (# 9) on a wireless phone such as a mobile phone, the currently displayed text mode is displayed on the LCD screen, and the user can select one of them.

When '# 9' (Character Mode Change Key) is pressed

1.Korean 2.Hangul consonants 3.Numbers 4.English (large) 5.English (small) 6.Special symbols

LCD screen

If you want to change the character mode without using the above, press the shortcut key for each character mode to change the character mode.

For example, pressing '# 1' immediately changes to Hangul text mode, and pressing '# 4' changes directly to uppercase English letter mode.

As illustrated in Table 1 to Table 4, the basic principles and concepts of the Hangul character input method of the present invention to define each character to correspond to 12 keys, and to implement the character input using the same,

Prior to all principles and concepts, the character input system of the present invention is thoroughly constructed for the convenience of the user. Complex, difficult parts operate only inside the system, and each part (module, routine) is configured so that the user can use the character input system in a simple and easy manner.

In addition, the text input system is described on the assumption that it is displayed on the "LCD screen" of a wireless telephone terminal such as a mobile phone or informs the user of the result of the user input through the ARS system (hereinafter, it is assumed that the "LCD screen").

Hangul structure

As described in reference to Figure 4, the structure of the Hangul is composed of a consonant, a consonant in the configuration, the consonant consonant + consonant, the neutral is a vowel + vowel + vowel, the final consonant is the maximum set of consonant + consonant, Two buffers A1 (A2) are initially assigned, three buffers B1 (B2) (B3) are assigned to neutral, and two buffers C1 (C2) are assigned to finality.

Using the Korean structure like this, when a user presses a dial button (number button) to input Korean characters,

The first input number is recognized as the first consonant A1.

The second input digit is recognized as the neutral first vowel B1.

The third input digit is recognized as the neutral second vowel B2.

The fourth input digit is recognized as the neutral third vowel B3.

The fifth input digit is recognized as the final first consonant C1.

The sixth input digit is recognized as the final second consonant (C2).

In the above, the reason for not recognizing the second input number as the first consonant (A2) and the basic principle as the neutral first vowel (B1) is that most letters in Hangul have two consonants, ie consonants, at the beginning. It is based on the fact that there are many things that start with a single consonant rather than one.

ㅇ Hangul combination

To implement Hangul with input consonants and vowels, all combinations are completed with a combination of single consonants and single vowels.

[A] is [ㄱ + ㅏ]

[Dog] is a combination of [a + [+ ㅣ].

Therefore, the double vowel [ㅐ] combining [ㅏ + ㅣ] does not exist separately. Only the vowel codes corresponding to the numeric buttons are [ㅏ] and [ㅣ]. If you want to use [ㅐ], [ㅏ] and [ㅣ Each number button corresponding to] is combined with [ㅐ].

In the case of double consonants (ㄲ, ㄹㅂ ...) similarly by pressing the respective number button to implement a double consonant.

ㅇ Completion of one letter

The character input system of the present invention regards the completion of a letter as "consonant + vowel + consonant". That is, the minimum combination of one character, "consonant + vowel", is not regarded as the completion of one letter, and the basic completion of one letter is considered as the consonant (single) consonant + neutral (single vowel) + finality (single consonant). If you don't have a finality, you can complete a letter with "Conversion", "Off", and "Enter". You can also indirectly complete a character in the form of "consonant + vowel" through the "character mode change key".

ㅇ To input only Korean consonants

If you want to input only Hangul consonants, select Hangul Consonant Text Mode.

However, even in Hangul text mode, you can enter only consonants, not completed one letters. Even if you finish typing "Hong Gilc", it does not recognize it as an error and accepts it as it is. That is, even if the consonant + vowel, which is a minimum Korean structure of one letter, can have the same effect as in the Korean consonant character mode.

ㅇ Convert (transition) key and delete key

The character input system of the present invention operates on both axes of "conversion (conversion in progress)" and "delete". The concept of "conversion" is introduced to eliminate predefined combination keys, implement simple and easy character input, and to control and assist in "conversion", and to "delete" to minimize the number of times the number button is pressed. The concept of introduced.

The conversion key function as described above will be described with reference to the flowchart of the Korean input conversion key of the present invention shown in FIG.

When the key value is received (S61) and the conversion key ("*") (S62), it is determined whether the conversion is possible by the state of the current character input buffer, that is, the state in which the last input value is stored (S63). The consonants or vowels to be converted are searched for according to the state of the character input buffer (S64) (see FIG. 4). Hangul constitution is searched by combining the found consonants or vowels (S65), and if Hangul is established (S66), the corresponding conversion character is stored in the character input buffer and the next input is received. The consonant or vowel of S is searched (S67) and the integrity search (S65) is repeated.

On the other hand, if the delete key ("# 0") (S68), it is determined whether there is a character stored in the character input buffer (S69), and if there is a character stored in the character input buffer, and deletes the last input character (S70) If there is no character stored in the character input buffer, the last character stored in the sentence buffer is deleted (S71). And, if other function keys, such as a space, enter key, etc. are input, each performs a corresponding function (S72).

As described above, according to the present invention, the conversion function by inputting the conversion key (*) is, if the conversion key is input, whether or not there is a conversion character corresponding to the last character stored in the character input buffer of the character mode and whether it is supported in each character mode. It is judged whether or not to be converted according to whether or not the conversion target is maintained and the status is maintained without conversion. In the case of the conversion target, in Korean consonant mode, the consonant and the corresponding consonant are converted to each other, and in English case, the character is converted into the next sequence of characters assigned to the button corresponding to the last character. When the character to be converted is the first consonant of the first consonant, the neutral first vowel is the double consonant according to whether the consonant is established in combination with the second consonant, and the second or third neutral vowel Is automatically converted to the consonant, the consonant, or the first letter of the next letter, depending on whether Hangul is supported. In the case of Jongsung, it is converted into a vowel sound or the first letter of the next letter depending on whether Hangul is supported.

Meanwhile, the delete function deletes only a single consonant or a vowel if the last input character is a single consonant or a vowel, and if the character to be deleted forms a double consonant in combination with the preceding consonant, the unit of a consonant is one unit. If no character is stored in the character input buffer but only in the sentence buffer, the last character of the sentence buffer is deleted. After the deletion proceeds, the internal state of the conversion process is returned to the previous state.

ㅇ Operation method of conversion

"Conversion" does not work on a completed character. In addition, it does not work even if the conversion cannot be performed.

The conversion possible state is defined in the internal module of this character input system.

A consonant can only have a single consonant or a double consonant (ㄲ, ㄸ, ㅆ, ㅉ ,,), and the neutral double vowels have consistent rules among the single vowels that are synthesized, and the single consonants and double consonants that can be used in the finality It is done according to the rules.

Hangul is a very scientific language, and faithfully, this character input system constitutes an internal module related to "conversion". The details of the configuration of this module are not covered here, but only some of the behavior of "conversion".

The concept of "conversion (progression)" is not limited to simply converting the phoneme state of the input Hangul, but rewriting through "conversion". In other words, the finish mark of one letter is part of the operation of "conversion (progression)".

The basic "conversion progress" sequence is as follows:

The first consonant (a, ct, ㅂ, 격) is converted into a vowel sound

The second vowel converts into consonants (ㄲ, ㄸ, ㅆ, ㅃ, ㅉ) or finality in association with the earlier consonants.

The third final transformation works internally with rewriting. It may be converted to a sound or to a next letter.

A "transformation" is internally defined in detail and operates on the basis of this.

If only "consonants" are entered, if "consonants + consonants",

"Consonant + Vowel", "Consonant + Consonant + Vowel", etc .......

In each case that can be combined, the state is completely identified and converted.

It checks whether conversion is possible according to the current input status and converts accordingly. "Transition" works differently each time an input is made, thus tracking the current input state and proceeding with the appropriate conversion.

ㅇ How delete works

In the above description, "delete" has been introduced to control and assist in "conversion" and to minimize the number of times the number button is pressed.

"Delete" is extremely simple from the user's point of view. When the delete key is pressed, the character input system of the present invention deletes the last input. However, "delete" does not mean simply to delete, but means that the internal state of "conversion (conversion)" is returned to the previous state in the character input system.

When the dial button is pressed and the corresponding consonants and vowels are displayed on the "LCD screen", the character input system refreshes the state of "conversion" according to the system's internal module every time an input is made. Set Deleting the last input means that the state of the current "conversion" must also return to its previous state. "Delete" returns the state of "conversion" to its previous state after deleting the last one entered.

As such, "delete" internally knows the status of "conversion" and has the ability to control, change, and assist it.

If the delete key is pressed while "ㄲ" is entered, it is decomposed into [a + a] to delete the entire "ㄲ" instead of deleting only the "a" after it.

In other words, double consonants (ㄲ, ㄸ, ㅃ, ㅆ, ㅉ) are treated as one unit and deleted. The core of the internal algorithm of the character input system is that the modules that manage the two parts of "conversion" and "delete" are organically combined with each other.

The module responsible for "deletion" knows the whole process of "conversion" and knows what to do if the delete key is pressed.

ㅇ How spacing works

When the user presses the corresponding dial button (##) for the spacing, the text input system unconditionally spaces regardless of the state of the sentences accumulated. In other words, no space is possible.

For example, if the user presses the space key (##) while typing only 'ㄱ' in the Hangul text mode, it does not recognize it as an error. However, if you press the space key (##) while only one consonant is entered in the Hangul text mode, no space will be given after 'ㄱ'. If the user presses "##" after entering "ㄱ", enters "b", then press "##" again, and enters "c". "Not" but "a". If you want to type "ㄱㄴㄷ", enter "ㄱ" and press "##" twice. Likewise, pressing '##' twice after entering 'ㄴ' enters a space. In principle, if you want to write only consonants, it is preferable to do it in Hangul consonant text mode. However, the reason for providing such a function in Hangul text mode is for the convenience of the user.

In the normal state, not all of the above, all the spaces work in the same way.

In other words, if you input "Right" and then do "##" and type "Lee", it becomes "We". In the Hangul consonant text mode, the input of "##" gives a margin of course unlike the Hangul mode.

ㅇ Operation mode of text mode change

Changing the character mode operates as described in Table 4 above. If "# 9" is pressed, it will show all the supported character modes and allow you to select them, and you can use the hotkeys (# 1 to # 6) to switch to that character mode immediately. If the change key is pressed to change the character mode while only the consonants are input in the case of Korean character mode, the character mode is changed without recognizing it as an error. That is, even if the completion of one letter is not achieved, the character mode can be changed.

ㅇ How Enter works

It works in a similar way to Enter on a computer keyboard. Enter, which means you have entered all the sentences, is the normal behavior, and can be used to mean that you have completed a single character if necessary. Later, the Enter key indicates that there may be a significant modification of the function. In case of Enter key, it is not recognized as an error even if only consonants are entered as in the case of the above space and character mode change key.

ㅇ Hangul consonant text mode

When the character mode is the Hangul consonant character mode, the conversion is performed in the order of "normal consonant ==> plethora ==> double consonant". In the Hangul consonant mode, the consonants are implemented by pressing the corresponding dial buttons, respectively, and converting them. However, in the Hangul consonant character mode, only the conversion is performed.

When dial button 1; A ==> ㅋ ==> ㄲ

When dial button 3; C ==> ㅌ ==> ㄸ

When dial button 6; ㅂ ==> = ==> ㅃ

When dial button 7; ㅅ ==> ㅆ

When dial button 9; ==>> ==> ㅉ

Spacing works by giving a space, changing the text mode works the same in all text modes, deleting deletes the last consonant (including double consonants), and pressing Enter to delete all sentences (words). It means that it is entered.

ㅇ Numeric character mode

In numeric text mode, there is no corresponding code as described above. It is implemented by recognizing the number on the dial button as it is. In the numeric mode, there is no "conversion (transition in progress)."

ㅇ English small letter character mode

"Conversion" in English upper / lowercase character mode converts in the order indicated on the corresponding dial button.

When dial button 2; A ==> B ==> C ==> (A)

When dial button 3; D ==> E ==> F ==> (D) and so on

If "C" is in the state of "conversion (conversion progress)", it returns to "A" and cycles.

Exception

On the other hand, the exception is based on the Hangul completion type (2350 characters) when "conversion (conversion progress)" has the following problems. In the case of a character such as "Why", when the conversion key is pressed, it should be converted into "ㅇ". However, the Hangul type "ㅇ" is converted to "Wah" because Hangul Completion (2350 characters) is not supported.

The letter "같은" is in Korean (2350 characters) but cannot be implemented. The reason for this is that the complete form (2350 characters) does not have the letter "ㄹ" and is not supported by the computer's operating system. Although it is possible to implement "뢨" by combining [ㄹ + ㅗ + ㅏ + ㅣ], it is not supported for the final form (2350 characters).

Therefore, "ㄹ" is implemented as "롸 ㅎ" and "뢨" is not implemented. Hangul like "ㅂ" is not implemented. Completion type (2350 characters) are "bok" and "ㅂ". If "Conversion (Progress)" operates while "Bok" is input, it must be "ㅂ" but not implemented.

However, the above problems are limited to the computer's OS and Hangul completion type (2350 characters). Otherwise, any Hangul can be implemented in this character input system. As described above, the character input system implements a combination of a single consonant and a vowel of a consonant, a consonant, and a vowel consonant.

Basic example of conversion progress

1) Consonant (when the input is single consonant only) → [to beep]

'ㄱ' ==> 'ㅋ' (converts to beep 'ㅋ' for button 1)

'ㄷ' ==> 'ㅌ' (converts to beep '격' for button 3)

'ㅂ' ==> 'ㅍ' (converts to the '6', the corresponding sound of button 6)

'ㅈ' ==> 'ㅊ' (converts to the phonetic equivalent of button 9)

If the conversion key (*) is pressed at 'ㅋ', it is converted back to 'ㄱ'.

The same is true of ㅌ, ㅌ, and ㅊ.

2) consonant + vowel → [with consonant]

"Go" ==> "ㄲ"

A + ㅏ ==> a + a

Converts the vowel '에' corresponding to button 1 to a consonant 'ㄱ'.

"More" ==> "ㄸ"

ㄷ + ㅓ ==> ㄷ + ㄷ

Converts the vowel 'ㅓ' corresponding to button 3 into a consonant 'ㄷ'.

If the conversion key (*) is pressed again at "ㄸ" and "ㄲ", it switches back to "A" and "More". If the delete key (# 0) is pressed at "ㄸ" and "ㄲ", the entire double consonant is deleted.

3) Consonants + Consonants + Vowels → [Cannot be subject to conversion]

In the case of "black", there is no "conversion" even if the conversion key (*) is pressed.

4) Consonant + Vowel + Vowel → [To]

"And" ==> "jade"

ㅇ + ㅗ + ㅏ ==> ㅇ + ㅗ + ㄱ

Converts the vowel '에' corresponding to button 1 to a consonant 'ㄱ'.

5) consonant + vowel + vowel + vowel → [to finality depending on support, or to first letter of next letter]

"Ru" ==> "a" <-"a" is not supported in complete (2350 characters). therefore

"Ru" ==> "and"

ㄱ + ㅗ + ㅏ + ㅣ ==> ㄱ + ㅗ + ㅏ + ㅎ

Convert the vowel 'ㅣ' corresponding to button 0 to a consonant 'ㅎ'.

After completing the letter "and", the consonant "ㅎ" is converted to the first letter of the next letter.

6) Consonants + Vowels + Consonants → [to the sound box or to the next letter]

"Trap" ==> "like"

ㄱ + ㅏ + ㄷ ==> ㄱ + ㅏ + ㅌ

The consonant 'ㄷ' corresponding to button 3 converts into a sonic 'ㅌ'.

"Close" ==> "d"

C + c + c ==> c + c + c

The consonant 'c' corresponding to button 3 is converted to the first letter of the next letter.

After completing the letter "da", "c" is converted to the first letter of the next letter.

7) Consonants + Vowels + Consonants + Consonants → [to the consonants or to the next letter]

"Value" ==> "Gap"

ㄱ + ㅏ + ㅂ + ㅅ ==> a + ㅏ + ㅂ + ㅅ

The consonant 's' corresponding to button 7 is converted to the first letter of the next letter.

After completing the letter 'A', 'ㅅ' is converted to the first letter of the next letter.

"ㅇ" ==> "읊"

The above "ㅇ" character is not supported in the complete form.

However, the "읊" character is supported, so in this case, the input "ㅂ" is automatically converted to "方".

ㅇ + ㅡ + ㄹ + ㅂ ==> ㅇ + ㅡ + ㄹ +

When "ㅂ" is entered while "" is entered, it automatically converts to "p" by "converting".

Therefore, the above input principles are programmed into the buffer state recognition and indication module 30 and the search and combination check module 41, and correspondingly, the character table is composed of single consonants, double consonants, double consonants, vowels, single vowels. And a Korean complete table for double vowel, triple vowel, and combination search, and process Hangul character input by processing input values according to the programmed principle. The Hangul Completion Table configures the combined characters of the intermediate stage for the completion of all Hangul that can be supported together into a table and searches whether the Hangul can be completed when the currently entered characters are combined.

7 is an example of inputting a Hangul sentence according to the present invention. The case of inputting the sentence "Let's play in a flower garden" is an example of inputting a process using the Hangul input sequence, combination search, conversion key, and spacing key described above in detail.

8 is an exemplary diagram of a Hangul input instruction manual for attaching to a phone employing a character input system according to the present invention, wherein a double consonant including a double consonant, a double vowel, a triple vowel, and the like by a single consonant or a combination of a single vowel Because it can be implemented, a brief description of its use can be given.

As described in detail above, according to the present invention, a partition sound, a consonant sound, a consonant sound, and the like can be implemented without having a predefined combination key, and a character can be embodied by pressing a dial button a small number of times.

In addition, the Hangul combination rule supports rewriting, so you don't have to press any key as a sign that you have completed the Hangul characters.Because the Hangul implementation implements consonants and vowels by combining single consonants and single vowels, There is an effect that can be written.

In addition, the double consonant ("ㄲ", "ㄹㅂ"), and the double vowel ("ㅐ", "ㅙ") is implemented as a combination of a single consonant and a single vowel in the implementation, it is not necessary to mark it separately on the dial button, accordingly Since the number of characters written on the button is small, the user can easily find the characters written on the button and input Korean characters.
