Description

Korean character input in mobile communication terminal

The present invention relates to a method of inputting Korean characters using a keypad in a mobile communication terminal, and in particular, a character including at least Korean using a keypad of a mobile communication terminal in which a minimum of Korean consonants and a Korean vowel for inputting Korean characters are adaptively arranged. It relates to a Hangul character input method that can be input conveniently and efficiently.

In recent years, with the expansion of general wired communication services, technical development and subscription to personal wireless communication services such as Personal Communication Service (PCS) based on Code Division Multiple Access (CDMA) technology. Thanks to the drastic increase in embroidery, various additional services have been developed and are currently being actively serviced.

In particular, among these additional services, the Hangul transmission service is of particular interest to users due to the specificity of performing the Hangul transmission function through a voice communication terminal.

In order to provide such a Hangul transmission service, a useful Hangul input system that can easily input a Hangul through a Hangul keyboard such as a keypad of a mobile communication terminal is required, and the Hangul input system can display all Hangul syllables that can be represented by the Hangul alphabet. The degree of convenience of comprehensive operation such as rich character expressive ability to express uniquely, simple key operation and easy understanding of Hangul keyboard layout when the user directly reproduces the character expressive ability. The higher the number, the better its availability.

In addition to the Hangul transmission service, the application field using the Hangul code input method using the keypad part is connected to the stock information telephone service via telephone, and then, when the desired company name is entered, it can be applied to the stock information service that informs the price. Applications include various telephone voice information retrieval systems such as library collection guides, ticket reservations, and unattended 114 services. Other applications include small notebooks, such as electronic notebooks and palm top computers. And a keyboard system as a substitute for a general keyboard system, an operation such as an Internet TV, a digital still camera, and an input device, and an input system having a similar structure and function, such as an electronic lock and an automatic teller machine.

In order to provide Hangul transmission service using a reduced size Hangul keyboard with a limited number of key buttons, such as the keypad of a mobile communication terminal, the alphabet of the language to be supported can be effectively duplicated on an electronic telephone keypad or a function key can be operated. By the user's intention, it should be able to quickly extract or combine the desired Hangul alphabet.

The method used for inputting Korean characters in such a general mobile terminal is to store all completed characters in memory and use them, and to input the consonants and vowels of "Cheon (·) 지 (ㅡ) 인 (ㅣ)" separately. It is a general view that a method of completing letters is used, and that the "Cheonjiin" method is much more convenient than the method of storing all completed letters in a memory and using them.

FIG. 1 is a diagram illustrating an arrangement relationship between a keypad, a consonant, and a Korean character of a vowel of a general mobile communication terminal.

As shown in the figure, the "Cheonjiin" input method, in the keypad 200 of the mobile communication terminal 100 distinguishes the buttons of consonants and vowels, "1, 2, 3" button corresponding to the vowel | ·, ㅡ ”character is assigned, and“ 4 ~ 9, 0 ”button assigns consonants to input Hangul.

On the other hand, "ㄲ, ㄸ, ㅆ, ㅉ" is to press the number three times (in the case of 'ㄲ', '4' button three times in a row). In the input of the vowels, all vowels are composed of a combination of a vertical line (ㅣ), a horizontal line (ㅡ) and a dot (·), and "ㅏ" denotes the number key button "1" of the keypad 100 of the terminal 100. -2 "," ㅓ "is" 2-1 "," ㅐ "is" 1-2-1 "and so on. For example, to complete the text "My", you must press "5-1-2-1" consecutively. To complete the text "Release", press "5-2-3-1-2" consecutively. Should give.

As described above, the Korean character input method using "Cheonjiin" completes the letter by a combination of consonants and vowels, and in particular, since all three vowels can be expressed with only three buttons, it is easy to input letters on the mobile communication terminal 100. On the side.

However, since various vowels must be represented by only three buttons, it is inconvenient to press a button from at least two times up to five times. For example, in order to input "Lyn" in "Lynx", you have to press "4-4-2-3-1-2-1-0" in order and you need 5 buttons to input vowel. Has a very inconvenient and inefficient problem in that the same key must be repeatedly pressed several times to use the input key for inputting Korean characters.

In addition, in the case of other methods, consonants should be keyed up to three times, vowels up to four times, and the problem of pressing a maximum of ten times to complete a letter.

Accordingly, the present invention is proposed to solve the above problems of the prior art,

It is an object of the present invention to conveniently and efficiently complete characters containing at least Korean characters in all kinds of telephones by using a keypad of a mobile communication terminal of a telephone type in which at least Korean consonants and Korean vowels are uniformly arranged.

Hereinafter, preferred embodiments of the method for inputting Korean characters in a mobile communication terminal according to the above technical concept will be described in detail with reference to the accompanying drawings.

First, a difficulty in inputting Hangul in a mobile communication terminal is to input various consonants and vowels with only a limited key. In particular, vowels are more complicated than consonants because of the large number of cases. Accordingly, the present invention is to simplify the input of the vowels to be able to input all the vowels up to three times or less key input.

Figure 2 is an exemplary view showing a preferred embodiment of the keypad unit in a mobile communication terminal according to the present invention, showing the arrangement of consonants and vowels used in the present invention with respect to the keypad (keypad) of the mobile communication terminal for convenience of input The input unit is arranged on the left side, and the Korean vowel input unit is arranged on the right side.

After the consonants "ㅋ, ㅌ,,, ㅎ" omitted in the accompanying drawings, respectively, press the "ㄷ,, ,, ㅂ," "buttons provided on the keypad unit 300 of the terminal 100. It is expressed by pressing the function button * which is "·". "B" is entered by first typing "ㅅ (5)" and then pressing "· (*)", and "ㅁ" is entered with "ㅅ (5)" first, followed by "· (*)" twice. You can input by pressing continuously. Therefore, all consonants except "ㅁ" can be represented by button input of the two keypad units 300.

When referring to the <Table 1> attached to the consonant input process in the keyboard layout of the keypad unit 200 as follows, the key input sequence is a number or "*, #" corresponding to successive pressing Means giving.

The reason why "ㅁ" is expressed as in <Table 1> is because the frequency used for the support is the least among "b, ㄹ, ㅁ". The input of the consonants among consonants is to press the key corresponding to each consonant, and the dual consonants can press each consonant in order.

Table 2 attached below is a table showing the input method for the dual bearing according to the present invention.

<Example>

"ㄸ": Enter button 2 (,, ㄸ) twice in sequence (2-2).

<Example>

"ㄵ": After entering 5 (ㅅ, ㅆ) button, enter * (·) function button to create "b", and then press 8 (ㅈ) button (5-*-8).

"ㄶ": After inputting 5 (ㅅ, ㅆ) button, enter * (·) function button to create "b", enter 7 (ㅇ, ㄹ) button, and press * (·) function button. Enter to generate "ㅎ" and enter (5-*-7- *).

"ㄺ": Enter button 7 (ㅇ, ㄹ) twice in succession to create "ㄹ", and enter button 1 (ㄱ, ㄲ) (7-7-1).

"ㅀ": Enter 7 (ㅇ, ㄹ) button twice in succession to create "ㄹ", enter 7 (ㅇ, ㄹ) button, enter * (·) function button to enter "ㅎ" Create and enter (7-7-7- *).

On the other hand, in the vowel input method, "ㅓ, ㅓ,, ㅜ, ㅡ, ㅣ" of the single vowels "ㅑ, ㅑ, ㅓ, ㅕ, ㅗ, ㅜ, TT, ㅠ, ㅡ, ㅣ" In <Table 2> is input by pressing the corresponding key of the keypad 200 once, "ㅑ, ㅕ, ㅛ, ㅠ" is input by pressing the corresponding key of the keypad twice, "ㅐ, ㅔ of the double vowel , ㅒ, ㅖ, ㅚ, ㅘ, ㅙ, ㅟ, ㅝ, ㅞ, ㅢ "inputs a single vowel first in the order in which the letters are written on the keypad, and then inputs a single vowel additionally in order to complete the double vowel. By entering the completed characters.

<Table 3> attached below is a table for vowel input. As shown in this figure, all vowels can be completed by three key inputs.

As described above, Hangul characters have the form of "consonants-vowels" or "consonants-vowels-consonants", and confusion arises as to whether the consonants following the vowels will be used as a consonant or the consonants of the next letter. In this case, the rule follows the input rule of the "double" keyboard of the general Hangul word processor.

On the other hand, the Hangul character input method in the above-described mobile communication terminal according to the present invention follows the following input rules.

First, the beginning of a sentence always starts with the input of consonants, the first consonant character entered after the vowel is recognized as the first consonant, and the second consonant following the first consonant is recognized as the double consonant consonant. The consonant following the consonant is used as the consonant of the next letter, and if there is a vowel following the single consonant consonant or double consonant consonant, the first or second consonant used as a consonant has the principle of going to the next consonant.

On the other hand, an embodiment of the Hangul character input method according to the present invention as described above is briefly illustrated as follows.

<Example>

"Hello": "ㅇ (7)"-"ㅏ (0)"-"ㄴ (5- *)"-"ㄴ (5- *)"-"ㅕ (#-#)"-"ㅇ (7) "

"Lyn": "ㅋ (1- *)"-"ㅗ (3)"-"ㅏ (0)"-"ㅣ (9)"-"ㅇ (0)"

According to the present invention described above, the method for inputting Korean characters in a mobile communication terminal, the method of inputting Korean characters using a keypad of a mobile communication terminal is adaptively adapted to each numeric key button with a minimum of Korean consonants and a Korean vowel uniformly. Using the keypad of the arranged phone type has the advantage that it is possible to completely input the characters containing at least Hangul characters very conveniently and efficiently.

In addition, the character input method has a short fingering distance (편리), the number of strokes (打 件 數) is reduced and the usage method is intuitively understood, so it is very convenient to use and has the advantage of efficiently entering Korean characters. .

In addition, it has the advantage of easy to store and find the Hangul keyboard, and has the advantage that can be easily applied to any character input system, such as a terminal having a portable telephone terminal, a conventional landline telephone terminal and a telephone type keypad. .
