Description

Hangul input method in mobile communication terminal {Method of Inputting Characters in the Mobile Communication Terminal}

The present invention relates to a Hangul input method in a mobile communication terminal. Particularly, a Hangul input method in a mobile communication terminal in which all consonants and vowels are inputted by pressing a combination of a corresponding legend key and a number key using a legend key in two presses. It is about.

In general, Hangul, which is based on the Unification of Korean Spelling, consists of 19 consonants, 21 neutrals, and 28 consonants. The theoretical number of letters that can be formed by combining the consonants, neutrals, and species is 11,172 (i.e., 19 x 21 x 28) pieces. However, the actual number of characters commonly used is about 2,500, and in the case of a commonly used completed code or combined code, 1,800 to 1,900 Korean characters can be expressed.

In the existing code system, 'ㄲ', 'ㄸ', 'ㅃ', 'ㅆ' and 'ㅉ' and 'ㅑ', 'ㅛ', 'ㅛ', 'ㅠ', 'ㅒ' ',' ㅖ ',' ㅔ 'and' ㅐ 'are assigned. In order to display the Hangul as a complete Hangul using the keys of the mobile terminal, there are about 12 numeric keys (ie, 1 to 9, 0, *, and #) to perform input corresponding to each vowel and consonant.

The liquid crystal display of the mobile communication terminal is currently installed in many sizes in the main body, and as data services such as short messages or e-mails by the Internet and Short Message Service (SMS) become available, not only Korean display but also Korean input can be further improved. It became more important.

As shown in FIG. 1, the Korean input device of the conventional mobile communication terminal includes a central processor 11 controlling a system and a program of the mobile communication terminal, and a screen switch key and a numeric key connected to the central processor 11. And a key input unit 12 which is composed of a plurality of keys such as an input completion key and allows a user to input a key value, and is connected to the corresponding central processor 11 and the key input unit 12 and in the central processor 11. Including a liquid crystal display 13 for displaying the result of the processing and displays the key value input through the corresponding key input unit 12, and a memory 14 connected to the central processor 11 and storing the Hangul font consist of.

Referring briefly to the operation of the Hangul input device configured as described above, when the user inputs a number or Hangul through the key input unit 12, the central processor 11 detects and checks the corresponding input key value and processes it. give.

In this case, the central processor 11 displays the number input through the key input unit 12 as it is through the liquid crystal display unit 13, and the Hangul input through the key input unit 12 is the memory 14. The inputted key value is searched by using the Korean font embedded in the display, and then displayed on the corresponding liquid crystal display 13 after the Korean input code is converted from the Korean combination code to the Korean complete code according to the Korean input internal automata by the Korean input key.

An example of Hangul input in a conventional mobile communication terminal will be described with reference to the key matrix of the terminal shown in FIG. 2.

First, look at the phonemes assigned to the numeric keys of the key matrix: 'ㅡ' at '1', '·' at '2', 'ㅣ' at '3' and 'ㄱ' at '4' 'ㅋ', '5' at '5', 'ㄹ', 'ㄷ' at '6' and 'ㅌ', '7' at '7' and 't', '8' at 'ㅅ' 'And' ㅎ, '9', 'ㅈ' and 'ㅊ', '0' and 'ㅇ' and 'ㅁ' are placed, '*' supports Korean-English conversion and English capitalization. Make sure you enter between the letters '#'.

The vowels are combined using the '1', '2' and '3' keys. For example, the '모음' of the '3' and the '·' of the '2' are consecutively inputted to 'ㅏ'. Combination of ',' '3' and '2' twice 'ㅑ' combination, '2' and '3' by inputting consecutively 'ㅓ' and so on.

The Hangul input method is simple in vowel input and convenient to store and convenient to input. However, since the vowel must be repeatedly selected after combining several keys, the number of keys to be pressed by the user increases. In particular, in the case of a double vowel, you have to press four or five times to enter one vowel.

For example, "what" should press 8 for the numeric keys 0, 0, 3, 2, 2, 1, 5, 5, and "look" for the numeric keys 7, 2, 3, 1, 3. You must press 5 in order, and "why" should press 6 in number key 0, 2, 3, 1, 2, 1.

As such, complex double vowels have the disadvantage of having to enter a vowel multiple times even multiple times.

In addition, an example of another Korean input will be described with reference to the key matrix of the terminal illustrated in FIG. 3.

First, if you look at the phonemes assigned to the numeric keys in the key matrix, one vowel is selected according to the number of times the child key is pressed at '1', 'b' at '2', and 'b' at '3'. 'ㅗ' and 'ㅓ', 'ㄹ' at '4', 'ㅁ' at '5', '6' at '6' ',' 7 ',' 8 ',' ㅇ ',' 9 ',' 9 ', one vowel is selected according to the number of key presses,' ㅣ ',' 0 ',' ㅡ ' Consonants and vowels not assigned above in combination with consonant keys (1, 2, 4, 5, 7, 8) or vowel keys (3, 6, 9, 0) It is made to be pressed before or after the consonant key or the vowel key respectively so that it can be assigned.

However, this Hangul input method is too difficult to input if you do not know where the consonants that are not written on the key because you do not realize the principle of double vowels or double consonants are used. ㅎ ',' ㅃ ',' ㅉ ',' ㄸ 'consonants and multiple double vowels, etc. is a disadvantage that is entered more than three times.

For example, "ja" should press four times in the order 7, *, #, 3, and "wave" should press four times in the order of 5, *, *, 3.

In addition, referring to the key matrix of the terminal illustrated in FIG. 4 as an example of the above-described method and another Korean input, the following description is made.

First, look at the phonemes assigned to the numeric keys in the key matrix: 'a' and 'b' at '1', 'c', 'ㄹ' and 'ㅋ' at '2', ' ',' ㅂ 'and' ㅌ ',' 4 'at' ㅅ ',' ㅇ 'and' t ',' 5 'at' ㅈ ',' ㅊ 'and' ㅎ 'at' 6 ' 'ㅏ', 'ㅐ' and 'ㅑ', 'ㅓ' at '7', 'ㅔ' and 'ㅕ', 'ㅡ' at '8', 'ㅗ' and 'ㅛ', '9' 'ㅣ', 'ㅠ' and 'ㅒ', 'ㅣ' and 'ㅖ' are placed at '0', '*' supports Korean-English conversion and English capitalization, and '#' is between character strings. To be entered.

The keys are assigned to one key each of three consonants and vowels, so that the corresponding phonemes are changed and input according to the number of times of pressing a specific key.

By the way, there are some consonants coming out by pressing the same key four times, and almost every key has three consonants or vowels arranged.

In addition to the shortcomings described above, when entering a symbol, it is necessary to switch back to the Hangul input mode after inputting a single symbol. Therefore, to use multiple symbols, the same operation, changing from Hangul to a symbol, finding a desired page, There was an inconvenience of having to perform a scrolling operation every time.

In order to solve the problems described above, the present invention introduces a legend key, pressing all the consonants and vowels two times or less, including the legend key (except, only one vowel 'ㅢ' three times as an exception) Pressing), so that the user can input the Hangul, the user does not have to repeat the same operation several times to input the Hangul to provide convenience to the Hangul input, the purpose is.

In addition, the present invention by placing the consonants on the left, 'ㅏ' and 'ㅓ' of the vowels on the right side, 'ㅗ' and 'TT' of the vowels to follow the Hangul alphabet arrangement shape and can be input simultaneously with both hands. The purpose is to reduce the number of keystrokes a user enters and make it user friendly.

According to an embodiment of the present invention, a Hangul input method of a mobile communication terminal includes: assigning a main consonant and a main vowel as a primary key; Assigning a vowel inputted by pressing the primary key corresponding to the main vowel as a duplicate key and combining the primary key and the duplicate key corresponding to the main vowel; Assigning an input consonant and a vowel by combining a basic key and a legend key by setting a legend key; Detecting a press of the primary key and displaying a corresponding consonant or vowel in a text input window and displaying a consonant or vowel which can be input by pressing the legend key; Detecting pressing of the legend key and combining the primary key and the legend key to display consonants or vowels corresponding thereto instead of the main consonants or vowels; And detecting a pressing of the duplicate key, combining the primary key and the duplicate key corresponding to the main vowel, and displaying the corresponding vowel instead of the main vowel. Here, the consonants assign keys to the left and upper positions, and the vowels assign keys to the right and lower positions.

Alternatively, a Hangul input method in a mobile communication terminal according to an embodiment of the present invention includes the steps of: setting a lock key for continuously inputting a symbol even after continuously inputting the symbol; Checking whether the lock key is pressed after checking whether a symbol is input; Storing the input symbol in a legend window when the lock key is pressed; The method may further include inputting a symbol stored in the legend window into the text input window at a time when pressing cancel or unlocking.

Alternatively, the Hangul input method of the mobile communication terminal according to an embodiment of the present invention may directly input consonants and vowels combining the basic and legend keys or directly input consonants and vowels corresponding to the duplicate keys. And a step of setting consonants and vowels corresponding to the keys, duplicate keys, and legend keys to the keys. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

A Hangul input method in a mobile communication terminal according to an embodiment of the present invention will be described with reference to the flowchart of FIG. 9 as follows.

First, set the primary key, duplicate key, and legend key to the example shown in Table 1 below. Here, numbers or symbols in parentheses indicate keys configured in the key input unit of the terminal. That is, as in the example of the key arrangement shown in FIG. 6, the number keys '1' to 'a', '2' to 'c', '3' to 'ㅏ' and 'ㅡ', '4' to 'ㅁ' ',' 5 ',' 6 ',' ㅓ 'and' ㅣ ',' 7 ',' ㅈ ',' 8 '' ㅗ 'and' 9 'and' TT 'and' * ' 'Key to' · ', numeric key' 0 'to' ‥ 'and' # 'key to'… ' ', Where the user uses both hands to feel friendly and easy to input, the consonant consonants according to the composition principle of Hangul left and top positions (1, 2, 4, 5 and 7) The vowels are assigned to the right and bottom (3, 6, 8, and 9).

Primary key Duplicate key Legend key ㆍ (*) ‥(0) … (#) A (1) B (1 *) (10) ㄲ (1 #) C (2) D (2 *) ㅌ (20) ㄸ (2 #) ㅁ (4) ㅂ (4 *) P (40) ㅃ (4 #) S (5) ㅇ (5 *) ㅎ (50) ㅆ (5 #) (7) (7 *) ㅉ (7 #) ㅏ (3) ㅡ (33) ㅑ (3 *) ㅐ (30) ㅒ (3 #) ㅓ (6) ㅣ (66) ㅕ (6 *) ㅔ (60) ㅖ (6 #) ㅗ (8) ㅛ (8 *) ㅘ (80) ㅙ (8 #) TT (9) ㅠ (9 *) ㅝ (90) ㅞ (9 #) ㅢ (336) ㅚ (86) ㅟ (96)

In other words, the primary key includes five main consonants of 'ㄱ', 'ㄷ', 'ㅁ', 'ㅅ' and 'ㅈ' and a main collection 4 of 'ㅏ', 'ㅓ', 'ㅗ' and 'TT' It consists of five, and assigns the five main consonants and the four main vowels from the number keys '1' to '9' and set them as the primary keys (step S1). At this time, referring to Table 2 below, which shows the consonant frequency of Korean consonants in the Korean Dictionary, the five main consonants correspond to the most frequently used consonants. Therefore, the number of key presses is actually less than 1.5 times. It is possible. In addition, since the four main vowels are also frequently used vowels, the number of key presses can be reduced to less than 1.6 to 1.7 times on average.

Consonant A N C D M ㅂ S ㅇ ㅈ H Lol ㅌ ㅍ ㅎ frequency(%) 14.5 3.9 7.4 0.5 6.3 9.5 13.5 15.4 11.8 4.5 1.0 2.3 2.8 6.6

In addition, the five vowels (ㅡ, ㅣ, ㅚ, ㅟ and ㅢ) inputted by pressing the numeric keys (eg, 3, 6, 8, 9) corresponding to the four main vowels repeatedly are displayed. Combining the two numeric keys (3, 6) to be pressed simultaneously with the numeric key corresponding to and assigns each of them to set the duplicate key, in the case of four vowels (ㅡ, ㅣ, ㅚ, ㅟ) If you press only two times, you can input, except in the case of 'ㅢ' only three times in the order of 3, 3, 6 (step S2).

When the user presses the number key corresponding to the primary key, the user detects the pressing of the primary key and displays the character input window and the legend window as shown in FIG. 5 to display the pressed key through the corresponding character input window. In order to display and select an expandable consonant or vowel in addition to the primary key through the corresponding legend window, that is, the keys of the '*', '0' and '#' keys are selected from the legend keys (... Each of the primary keys and the legend keys is assigned to each of the basic consonants and the vowels (step S3).

By setting the '#' key as a key for performing a lock function, when the '#' key is pressed during continuous input of a symbol, the symbol can be continuously entered without exiting after the symbol is input. To perform a function for performing the operation (step S4). Here, the symbol input method uses the '#' key as a lock key, and after checking whether the symbol is in the symbol input state and detecting the pressing of the '#' key in the symbol input state, the symbol selected and input by the user without exiting Symbols stored in the legend window when they are canceled (ie return) or unlocked (that is, when the '#' key is pressed again) are remembered in the legend window used by the Korean input method. Eliminate the need to repeat the same thing by typing in the input window at once.

Accordingly, when the user presses a numeric key (ie, 1 to 9) corresponding to the primary key, the user detects the pressing of the numeric key corresponding to the corresponding primary key (step S5). The key (i.e., main consonant or main vowel) is displayed in the character input window (step S6), and a legend window is displayed below the corresponding character input window to read and display the consonants or vowels that can be input using the legend key. (Step S7).

Then, the user checks whether the '*', '0' and '#' keys corresponding to the legend key are pressed (step S8), in which case the eighth step (S8) corresponds to the legend key. If it is detected that the key is pressed, the Jamo displayed in the seventh step S7 is deleted, and instead, the corresponding key is displayed by combining the basic key and the legend key (step S9).

On the other hand, if the eighth step (S8) does not detect the pressing of the key corresponding to the legend key, to check whether there is a pressing of the numeric key (ie, 3, 6) corresponding to the duplicate key (step S10) In this case, when detecting the pressing of the numeric key corresponding to the duplicated key in the tenth step (S10), the vowel corresponding to the duplicated key is displayed (step S11).

By repeatedly performing the operation as described above, that is, the operation from the fifth step S5 to the eleventh step S11, all the letters are input by pressing two keys.

First, a method of inputting consonants will be described as follows.

First, as shown in Table 1, there are 19 consonants, and each of the five main consonants ('ㄱ', 'ㄷ', 'ㅁ', 'ㅅ', and 'ㅈ') is set as a primary key, and each number key ' 1 ',' 2 ',' 4 ',' 5 'and' 7 ', and' · ',' ‥ 'and'… '. 'As the legend key and assign it to the keys of' * ',' 0 'and' # 'respectively, and each primary key and each legend key will be displayed when the corresponding primary key is pressed. Allocate them in combination.

Therefore, press '1' to display 'ㄱ' in the text input window, 'b', 'ㅋ' and 'ㄲ' in the legend window, and press '*' after pressing '1' to enter text. Display 'b' instead of 'ㄱ' in the window, press '2' to display 'b' in the character input window, 'd', 'ㅌ' and 'ㄸ' in the legend window, After pressing '2' and pressing '*', all consonants can be entered by pressing the key twice or less, such as displaying 'ㄹ' instead of 'ㄷ' in the character input window.

Secondly, the input method of the vowel is described again as an example.

First, as shown in Table 1, there are 21 vowels. The four main vowels ('ㅏ', 'ㅓ', 'ㅗ' and 'TT') are set as primary keys, respectively, and the numeric keys' 3 'and' 6 ',' 8 'and' 9 ', and the five vowels (ㅡ, ㅣ must be pressed repeatedly by pressing the number keys corresponding to the four main vowels (eg, 3, 6, 8, 9). , ㅚ, ㅟ, and ㅢ) are set as duplicate keys and assigned by combining the numeric keys corresponding to the four main vowels and the two numeric keys (3, 6) to be pressed repeatedly, respectively. 'And'… 'As the legend key and assign it to the keys' *', '0' and '#' respectively, and if you press each of those primary keys, a collection of lines will be displayed in the legend window. Allocate them in combination. Here, 'ㅏ' or 'ㅓ' always located on the right side of the consonant should be placed on the right side (3, 6), and 'ㅗ' or 'TT' always on the bottom side of the consonant. By setting it to be user-friendly and convenient for both hands to type.

Thus, pressing '3' displays 'ㅏ' in the text input window and displays 'ㅑ', 'ㅐ' and 'ㅒ' in the legend window.Press '3' and then press '3' to enter text. Display 'ㅡ' instead of 'ㅏ' in window, press '*' after pressing '3', display 'ㅑ' instead of 'ㅏ' in character input window, press '6' to input character Display 'ㅓ' in the window, 'ㅕ', 'ㅔ' and 'ㅖ' in the legend window, press '6' and then press '6' in the character input window instead of 'ㅓ' You can enter all vowels with two or fewer keystrokes, such as displaying ',' and pressing '6' followed by '*' instead of 'ㅕ' in the text input window. .

To enter "what" in the same way as above, just press 5 times in the order of 4, 9, 0, 2, *. "Look" just press 4 times in the order of 4, *, 8, 0. 'Is just 4 times in order of 5, *, 8, #.

As compared with the conventional Hangul input method, the Hangul input method according to the present invention has a low number of inputs due to a slight numerical difference in a general terminal sound or a short vowel, but in the case of a double vowel consonant or a complex consonant, the legend key of the present invention is used. It can be seen that the Hangul input method used is much lower.

On the other hand, when there is no legend window, if there is only a primary key, there is a possibility that crosstalk occurs when inputting consonants, and examples of key arrangement in a mobile communication terminal according to an embodiment of the present invention are provided to eliminate this problem. This allows the user to view the corresponding key arrangement and input a letter combination combining the primary key and the legend key or a letter corresponding to the duplicate key.

As described above, according to the present invention, by introducing a legend key so that all consonants and vowels including the legend key can be input by pressing two or less times, the user may input the same operation several times. It can be provided as a convenience for Korean input by eliminating repetitive work.

Also, according to the present invention, the consonants are placed on the left side, 'ㅏ' and 'ㅓ' on the right side, and 'ㅗ' and 'TT' on the bottom side of the vowel to follow the shape of the Hangul alphabet and input simultaneously with both hands. By doing so, the user can reduce the number of keystrokes and make the user friendly.

In addition, according to the present invention, in the symbol input method, by pressing the corresponding lock key in the symbol input state by using the lock key, a plurality of symbols selected by the user are written at a time to be written in the input window. Can be removed.
