Description

Character input device and method of mobile communication terminal {Divice for input character of cellular phone and, Method for as the same}

The present invention relates to a character input device and method of a mobile communication terminal, and in particular, by adding a character input function to a direction key generally used in a mobile communication terminal to generate a character input signal by parallel operation with a numeric key to which a character is assigned. The present invention relates to a character input device and method for a mobile communication terminal.

Recently, with the introduction of digital cell phone service, various information terminals that need to send and receive texts along with text service through telephones have been developed, and various methods have been developed to try to enter texts using only the keyboard of the phone, not the computer keyboard. As information and communication devices become smaller, the number of input buttons decreases. However, as the function is improved in inverse proportion to the reduction in size, the necessity of inputting characters continues to increase.

In case of Hangul, based on the unification method of Hangul spelling, Choseong is a, b, c, d, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅁ, ㅋ, ㅌ, ッ, ㅎ, and neutral is ㅏ, ㅑ, ㅓ , ㅕ, ㅗ, ㅛ, ㅜ, ㅠ, ㅡ, ㅣ, ㅐ, ㅒ, ㅔ, ㅖ, ㅘ, ㅙ, ㅚ, ㅝ, ㅞ, ㅟ, ㅢ, and the finality is a, b, c, d, ㅁ , 으로, ㅅ, ㅇ, ㅈ, ㅋ, ㅋ, ㅌ, ,, ㅎ, ㄱㅅ, ㄴㅈ, ㅎㅎ, ㄹㄱ, ㄹㅁ, ㄹㅅ, ㄹㄱ, ㄹㅍ, ㄹㅎ, ㅂㅅ. In addition, the theoretical number of letters that can be formed theoretically by combining initial, neutral, and final is 11,172 characters, but the actual number of commonly used characters is about 2,500 characters, and in the case of commonly used completed codes or combination codes, about 1,800 to 1,900 characters. I can express Hangul. In the existing code system, when the keyboard is input, ㄲ, ㄸ, ㅃ, ㅆ, ㅉ and ㅑ, ㅕ, ㅛ, ㅠ, ㅔ, ㅖ, ㅐ, ㅒ are allotted. In order to display the Hangul as a complete Hangul using the keys of the terminal, there are about 12 keys (1, 2, 3, 4, 5, 6, 7, 8, 9, 0, *, #) provided in the terminal. Inputs corresponding to consonants and vowels of.

Accordingly, since a character must be input with a limited input button, a plurality of characters are assigned to one button, and then, when selected, the character is continuously pressed to perform the character input.

For example, a mobile phone, which is a small and generalized product using a Korean input device, is described. As a character input key of a mobile phone is used in a limited number, it is necessary to assign several consonants and vowels to a single button. Select one letter by finding consonants, vowels in the button, and pressing the button as many times as necessary, and then move to the next space with the cursor movement key, and then select the next letter in the same way. This method is very inconvenient because the user does not input the characters but combines the characters one by one, making it difficult to input a large amount of characters because the input method is difficult, and it is possible to input Korean and English characters continuously. Character input is very inconvenient.

In addition, at least 24 letters, including 14 consonants and 10 vowels, are required to fully implement Hangul. However, since the phone keyboard contains only 12 special symbols, at least two letters are assigned to each number. For this reason, complicated rules have been proposed to determine which of the two or three letters written on the keyboard should be applied when a particular keyboard is pressed.

Because of these rules, the process of assembling letters as you think about the letters you need to type is very complicated, not easy, and there are twelve keyboards to enter the letters because there is a mixture of letters that are frequently used and not frequently used in the composition of the keyboard. It is often uncomfortable to input frequently used consonants or vowels because of the fact that they are used up and down diagonally and the frequency of Hangul alphabet is not considered at all.

In addition, in Japanese, there are many types such as hiragana, katakana, sound, bass, and touch, so it is very difficult to display the entire Japanese language with limited input buttons such as mobile phones. In order to overcome this problem, several letters are assigned to one button, and one letter is selected by inputting as many numbers as necessary, and then moved to the next space with the cursor movement key, and the next letter is selected in the same manner as described above. The same is true for English. This method is not only very inconvenient because the user is inputting characters, but a process of creating letters one by one, and it is difficult to input a large amount of characters because the input method is difficult. In order to overcome this problem, a liquid crystal, which is a character output unit, is adopted as a large one, and the hiragana and katakana are displayed on the liquid crystal, and the user selects the corresponding character by the selection means. . Even if the above method is adopted, the size of the liquid crystal is large, and since it is necessary to introduce a separate hardware for selection, the situation is inconvenient in terms of price and use.

Accordingly, an object of the present invention is to add a character input function to a direction key generally used in a mobile communication terminal, to generate a character input signal in parallel with a numeric key, but to input a Korean vowel with a direction key and a consonant. Character input device of a mobile communication terminal configured to generate a character input signal by operating a numeric key to which a vowel is selectively assigned, or to generate a character selection signal for selecting a character in a character string assigned to a numeric key when inputting English or Japanese characters And providing a method.

2 is a diagram illustrating a configuration of an input unit for inputting Korean characters according to an embodiment of the present invention. Referring to FIG. 2, the arrangement of the Hangul alphabets assigned to the numeric keys 100 of the input unit 1 is divided according to the numeric keys 100 and the number of repetitions as shown in Table 1, and in Table 2, the direction keys ( 103 shows the array of vowels assigned to it.

Hangul consonants a, b, c, d, b, k, k, k, k, k, k, k, k, k, k, k, k, k, k, and vowels k, k, k, k 숫자, ㅗ, ㅛ, ㅜ, ㅠ, ㅡ, ㅣ, ㅐ, ㅒ, ㅔ, ㅖ, ㅘ, ㅙ, ㅚ, ㅝ, ㅞ, ㅟ, ㅢ among the 상기, ,, ,, ㅟ, ㅢ , ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅁ, ㅋ, ㅌ, ,, ㅎ, ㄲ, ㄸ, ㅃ, ㅆ, ㅉ and assign ㅗ, 에는 to the up arrow among the arrow keys 103, Assign ㅏ and 에는 to the directional keys, assign TT and ㅠ to the directional keys, and assign ㅓ and 에는 to the left key.

Also, ㅣ, ㅝ, ㅞ and ㅡ, ㅘ, ㅙ were assigned to the number 2 and number 3 keys of the number keys 100, respectively.

On the other hand, it will be apparent that among the remaining vowels ㅐ, ㅒ, ㅔ, ㅖ, ㅚ, ㅟ, ㅢ is completed by a combination of the vowels assigned to the direction key 103 and the numbers 2 and 3 keys.

The Hangul alphabet assigned to the numeric key 100 and the direction key 103 is databased and stored in advance in the storage unit 2.

The user displays the Hangul characters on the output unit 3 by the operation of the input unit 1 while the user is able to input the Hangul characters by the operation of the general key 109 of the mobile communication terminal. For example, if you want to enter the letter "a" first, if you enter the number 1 number once, "a" is displayed on the output unit (3), and if you enter the right key once, "ㅏ" is displayed. In combination with "a", the Korean character "ga" is displayed on the output unit 3 by finally inputting two keys.

In addition, if you want to enter the letter "Ga", enter the number 1 key once, "ㄱ" is displayed on the output, and then enter the right key twice, "ㅑ" is combined with "ㄱ" The Korean character "Gya" is finally displayed on the output unit 3 by three key inputs.

In addition, if you want to enter the character "strong", if you enter the number 1 key once, "a" is displayed on the output unit (3), and if you enter the next right key once, "ㅏ" is "a" Combining to the letter "ga" is combined with "7" by inputting the number seven times, and then by combining "ㅇ" to display the Hangul characters to the output unit 3 in the last three key input.

In addition, if you want to enter the letter "Yes", if you enter the number seven times once "ㅇ" is displayed on the output (3), then if you enter the left arrow twice, "ㅕ" is "ㅇ" Combining with the letter "F" and then by inputting the number 2 number once, "" by combining "Hangul" characters are displayed on the output unit (3) by the last four key inputs.
