PURPOSE: A phone key pad is provided to input Hangul, Korean Language by converting consonants and vowels of the Hangul into number and special character codes in order to express the Hangul on a LCD of a cellular phone or a pager by pushing the key buttons on the key pad. CONSTITUTION: A phone key pad includes 12 key buttons including the consonants and vowels of the Hangul classified into 12 groups. For example a group of (b, pp, p) is arranged on the number 1 key button. So the first vowel or consonant among the group is inputted if a corresponding number key button is pushed one time. The second one is inputted if the key button is pushed twice, and the third one is inputted if the key button is pushed 3 times.

Description

Phone Button for Hangul Input for Creating a Korean Unique Code {Convenient telephone button for Hangul encoding}

The present invention easily converts all letters used in real life into codes consisting of numbers and special characters #, * by simply pressing the consonants and vowels displayed on the phone keyboard using the production principle of Korean characters and the character composition features of vowels and vowels. Its purpose is to create a phone keyboard that can enter Korean characters on other phones, pagers, mobile phones and other machines that can display other characters.

Conventional Korean input method has been applied for several patents related to communication devices of the hearing impaired.

In 1991, the Automatic Interpretation Research Team of the Korea Telecommunications Software Research Institute developed a system for inputting text using an electronic phone. Has been admitted, but is rarely used due to inconvenience in use.

Recently, with the introduction of digital mobile phones and PCS services, various information terminals that need to send and receive texts along with text services through telephones have been developed, and various methods have been developed to try to enter text using only the keyboard of the phone, not the computer keyboard. come

However, in order to fully implement Hangul, at least 24 letters, including 14 consonants and 10 consonants, are required. However, since the phone keyboard has only 12 symbols including special symbols, at least two letters must be assigned to each number. Because of this, complex 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.

For example, a can be pressed as shown on the phone keyboard, but in order to enter ㄲ, you may need to enter special characters #, *, etc. In some input methods, you must press a specific button to enter a vowel. Most of the methods are configured to function only with the letters #, *, etc., which are not related to the letter, in addition to the letter shown on the phone keyboard.

Because of these rules, the process of assembling letters is very complicated and not easy, and in some cases it is necessary to enter the keyboard more than 7 ~ 8 times to make Chinese characters. 'S input and transmission are not being used significantly

In addition, Hangeul has scientific rules that are often used and not used between vowels and consonants, between vowels and vowels, or between consonants and consonants. The use of twelve keyboards up and down diagonally or the frequency of Hangul alphabets were not considered at all, so that the input of frequently used consonants or vowels was inconvenient.

In other words, there has never been an efficient keyboard input for Hangul input that considers the use and regularity of the Hangul alphabet.

Therefore, in the present invention, in order to solve this problem, the Hangul characters that can be easily converted and transmitted or inputted by converting all the characters used in real life into the corresponding unique codes in an easy and intuitive way through scientific analysis of the Hangul alphabet. Invented a telephone keyboard for input

In the present invention, by applying a simple rule that anyone can easily understand by typing the letters in the order of writing the Hangul alphabet written on the phone keyboard by pressing the keyboard of the computer, the unique code of the Hangul by itself according to the resources of the Hangul The main focus is to arrange the vowels and consonants on the keyboard as effectively as possible.

In order to find such an arrangement, after analyzing all 2,600 letters of the complete Hangul alphabet in real life, after systematic classification on the relationship between the initial and the neutral and the relationship between the neutral and the final, the letters are placed at the same time. And he wanted to develop a keyboard that could represent all letters without special signs or rules.

In addition, by analyzing the letters that make up the words of Hangul, we arranged the keyboards to make letters easily by placing vowels and vowels with high frequency or common use at close distance.

1 is a phone keyboard for inputting Hangul to create a unique code Korean

The keyboard of this phone can generate Korean characters in the mobile phone, letter pager, or any device that can display characters by pressing the keyboard like a letter.

Hereinafter will be described in more detail with reference to the accompanying drawings and embodiments.

1 is an example of the keyboard configuration proposed in the present invention, the method of implementing characters is the same as hitting the computer keyboard.

In other words, simply press the alphabet shown on the keyboard in the order of the letters. The simple rule is that the first displayed consonant is pressed once by the corresponding keyboard, the second displayed by the second letter, and the third is displayed by the third letter. Recognized as being given a code

In this way, when the input of the Hangul characters is finished, by pressing the 0 key, which is an indication of input, the unique code of the character is completed and can be displayed on all devices capable of displaying the characters.

In the keyboard of Fig. 1, for example, keyboard 1 is implemented by pressing the first keyboard once, the second keyboard twice, and the first keyboard three times.

In the same way, if the patent is expressed in a telephone keyboard, and you press ㄷㄷㄷ ㅡ ㄱ 0 ㅎ 대로 0 according to the letter shown on the keyboard, ㄷㄷㄷ can be recognized as 대로 and display the word patent as described above.

In addition to the rules used to make these letters, to create a sentence, you need a keyboard to display a space, which can be expressed by pressing # after the letter is completed with zeros.

For example, the sentence "Come home" can be expressed as ㅈ ㅣ ㅂ 0 ㅇ ㅔ 0 # ㅇ ㅗ 0 ㄹ ㅏ 0.

An example of this usage is shown in Table 1 below.

Table 1

The user enters characters as they are typed on the keyboard, but the phone is displayed with a number and a special character code corresponding to the pressed letter.

In other words, even if you enter a sentence to come home, the phone generates a code of 2 # 1080 # 0 # 870980 and is transmitted to the other party through the telephone line in the form of DTMF to be restored to the character again in the device displaying the character

And when this number is restored back to Hangeul, the scientific jejeori of Hangeul is applied as it is.

In other words, all the letters of Hangeul are composed of Chosung + Neutral or Chosung + Neutral + Jongsung, and Chosung and Jongsung must be composed of consonants and Neutral is composed of vowels, so the first number in the number code is 2 # 1080 # 0 # 870980. Is recognized as a consonant and is represented by 2 = ㅈ, # = ㅣ, 1 = ㅂ

Since the number 0 after 2 # 1 indicates that a letter has been entered, it does not correspond to a letter, and the next 8 is regarded as a first consonant and is recognized as 8 = ㅇ, and the next 0 is a neutron sign. Instead of recognizing 0 = ㅔ, the letter "E" is displayed. The following zero means Korean input, and the # after it has no consonant, so it is recognized as a space rather than a vowel. Initially entered sentence is restored

In order to restore the code back to Hangul, all the character codes that can be made like the completed Hangul are stored in the memory of the character display device in advance, and the Hangul corresponding to the numeric code is inputted in sequence or in accordance with the principles of Hangul disciples. There is a way to apply the restoring (combined Hangul) algorithm to the character display device's processor.

From now on, I will explain how the user can change the code that can be restored to Korean later by simply pressing the letter in the order of writing.

Just like the existing method, the code for Hangul is spontaneously completed by combining the letters on the keyboard without any special rules or appointments such as typing with special characters to display the bokja or vowels. It is possible to arrange the alphabet of the phone keyboard by using the Hangul's scientific words and features of the Hangul alphabet.

In the keyboard shown in Fig. 1, three rules were applied to group the alphabet into 12 keyboards.

As the first rule, a, c, ㅂ, ㅅ, ㅅ, which can make a rhythm and a sound, are similar in pronunciation or shape, so (ㄷ, ㄸ, ㅌ), (ㅂ, ㅃ, ㅃ), (ㅂ, ㅃ, ㅈ), Groups can be made with (ㅅ, ㅆ) and arranged on the same keyboard, but not with vowels, with only consonants, or in special cases, ㅛ, ㅠ, ㅑ, ㅕ can be arranged with this group.

Here, the order of arranging within the group can be changed, and in general, the order of (consonants, horns, and vowels) is most preferable, but in some cases (consonants, vowels, horns) can be arranged in the same keyboard as the double vowels.

The same vowels, ,, ㅡ cannot be placed on the same keyboard because they can be confused by the use of the finality when arranged together.

For example, suppose you arranged a, ㄲ, ㅋ and vowel 같이 together on keyboard 4. The user presses 4440 to enter a song, but since the nose can also be represented as 4440, this class of consonants cannot be grouped together with vowels.

For example, suppose you have arranged 3, ㄷ, ㅌ and vowel 같이 together on the 3rd keyboard. If you restore the letters corresponding to 3330, the letter デ ィ of this code is not implemented in the complete Hangul. This numeric code is recognized as the letter 않으므로 because it is neither used nor rarely used. Thus, vowels such as "ㅑ, ㅛ, ㅛ, ㅠ" can be arranged on the same keyboard.

The second set of vowels, "ㅏ, 모, ㅣ", is used to group the vowels or arrange the vowels together. In particular, the vowels that make triple 삼 and ㅙ cannot have any consonants and vowels.

The reason for the second rule is that 68 * 0 number codes are not recognized as a statement because assuming * is placed together on the keyboard, if you press 68 * 0 to enter something, the * after 8 may be recognized as b. It is possible

That is, ㅗ, 는, which forms a double vowel with ㅜ, must be combined with consonants that cannot be supported for this reason.

Therefore, ㅏ and ㅓ should be arranged separately on the keyboard without consonants. Among them, the vowels should be placed separately on the keyboard because the vowels cannot be grouped together for the same reason.

The third rule, the consonants "b, ㄹ, ㅇ, ㅁ, ㅎ" etc., can be arranged in the same keyboard by pairing one of "ㅗ, TT, ㅡ", among which ㅎ is the same keyboard Can be in the same group

With these three rules, you can complete the basic 12 groups of consonants and vowels that form letters by typing them in the order of writing, just as you enter a computer keyboard with a phone keyboard.

By using these rules well, if the proper group is determined, the input time is minimized by arranging the frequency of Hangul alphabet and the consonants and vowels that are frequently used in order to minimize the movement distance of the alphabet.

When analyzing the letters that make up the actual Korean words, the consonants are used in the order of "ㅇ, ㄴ, ㄹ, ㄱ, ㅅ, ㄷ, ㅁ" and "ㅇ" is the largest in their frequency of use.

Therefore, consonants with high frequency are arranged around the consonant "ㅇ". Especially, "AB" and "ㄹ" which are frequently used next to "O" consonants are arranged close to improve the efficiency of letter input. Place the "ㅓ," to write near and place the vowels with 7 vowels and vowels often to minimize the movement of the finger to enter letters.

In addition, the arrangement of letters on the phone keyboard is arranged so that they can be memorized easily even if the letters are not written on the keyboard.

If the consonants are arranged randomly in 19 consonants, including horns and horns, it is difficult to use them unless most of the existing phones are replaced. Important factor in design

And as in the case of foreign countries, the consonants and vowels are carefully arranged so that the consonants and vowels are evenly distributed over 12 keyboards so that the company name or product name can be used as the corresponding telephone number.

Using the keyboard of FIG. 1, for example, the JoongAng Ilbo's telephone number can be 2881 corresponding to ㅇㅇ by taking only the consonants of each letter. Could be utilized

These uses are actually used in foreign countries, and when the text input phone is activated, this aspect will be an important factor. Therefore, the consonants are evenly distributed to meet these uses.

In addition, conversion to Korean input, English input, and numeric input can be displayed by arranging # and * symbols appropriately.

The telephone keypad filed in this patent shows the keyboards that can most effectively meet these keyboard configuration rules in FIG.

Using the phone keyboard of the present invention, it is possible to generate a unique code uniquely for each letter of the Hangul as simple as writing without a separate code table or complicated input rules, and the moving distance for pressing the keyboard is significantly higher than the existing methods. Short and small number of inputs per character enables efficient transmission of characters through the phone, further improving the performance and utility of the phone.
