Description

Expanded telephone keypad system accepting Korean characters}

The present invention relates to a keyboard system for inputting Korean characters of a telephone, and more particularly, to a keyboard input system for Korean characters that enables a user to easily input Korean characters when inputting Korean characters through a telephone.

Conventional telephone keyboard systems have been used primarily for dialing numbers because they are made for the purpose of dialing the phone number of the other party. However, in recent years, the need to input a simple text message or the name and trade name of the other party is gradually increasing. For this purpose, various methods of inputting Hangul into the existing telephone keyboard system have been proposed.

However, many methods proposed so far have been to assign Hangul alphabet to the existing 4x3 phone keyboard. That is, it is very complicated because 24 Hangul alphabets are assigned to 12 keys. Since the key arrangement is complicated, the method of pressing it is also complicated, and the average number of keys that must be pressed in order to input a single phoneme is described in more detail as follows. It is about making it easy to enter almost all the letters in use with a relatively small number of keys. Furthermore, it is also important that these Hangul keys should be standardized. Previously, the Hangul fonts for computer keyboards used to be mixed with 2 beol and 3 beol, but now, at least, the most prominent Korean characters are distributed in Korea. Font is standardized. Currently, the Hangul alphabet commonly used is shown in the table below. Basic consonants are called terminal consonants, and double consonants and rich consonants are sometimes referred to collectively as double consonants. Since the basic consonants and double consonants are used for both the initial and the final consonants, they are used frequently, and since the rich consonants are used only for the final consonants, their frequency is relatively small. For the consonants, the individual keys are allocated, and for the consonants, the same key as the corresponding basic consonants is allocated, but when entering the consonants, the [Shift] key is pressed and the corresponding key is pressed. Since the low-frequency consonants have a low frequency of use, they do not have to be given separate keys, and the two main consonants are pressed in sequence, so that the corresponding lower-level consonants are entered. Separate keys are assigned for 'ㅐ' and 'ㅔ' which are relatively frequently used. 'ㅒ' and 'ㅖ' allocate the same key as 'ㅐ' and 'ㅔ', but press the [Shift] key. It is supposed to be a key. Since the remaining 7-character parent sounds are less frequently used, they are not given separate keys and two keys are pressed in sequence so that the parent sounds are input.In these standardized computer keyboards, various ergonomic design factors In consideration of this, the consonants are collected and arranged on the left side, and the vowels are arranged on the right side. Therefore, research to date has focused on inputting Korean characters using 12 keys, which are standard keys arranged as dial buttons of an electronic telephone. Therefore, in the design of the Hangul font for dial buttons of a telephone, user input There was little consideration of the ease of use, and how to collect the 51 consonants with the 12 keys. As a result, some products designed a variant of the so-called `` Chinese Hangul Key '' to reduce the number of keys required, and each designed in a way that had the proper number of consonants per key. And vowels are divided and input. In some products, there is almost no distinction between consonants and vowels, and some products are placed above or below, and only some products have three or four vowels. In order to use the Hangul keys that are developed and applied in this way, users must learn the function of each key to input the corresponding key for each product they purchase.

Looking at the Hangul character input function of the existing mobile phone, it can be seen that a lot of effort is required to learn the function. That is, the learning of the function is difficult, and there is a problem that most users do not use the function well.

As a result of the experiment, in order to input one phoneme, the average keyboard had to press the key more than 1.5 times on average. When measuring the average time it takes to enter, it took 270 to 300 seconds. This is because the existing keyboard layout does not match the common sense of the general public and how to use it is not easily mastered. As described above, the Hangul pad that is applied to the dial button for a telephone can be easily used by the user. Its development is seriously demanded, and it is also urgently required to standardize it urgently by adopting appropriate methods.

The present invention has been made to solve the problems of the prior art as described above, it is an object of the present invention to provide a keyboard input system for the Hangul input the user can easily enter the Hangul characters through the phone. In addition, in the present invention, so that users familiar with the computer keyboard can easily memorize and master the key position, the consonants are arranged on the right side of the Hangul pad implemented using the dial button for the phone, and the vowels are collected on the right side. We want to provide the Hangul alphabet you placed.

3 is a block diagram of a keyboard system for inputting Korean characters of 4x5 size according to another embodiment of the present invention.

According to the present invention for achieving the object as described above, it comprises 10 Arabic numerals (0 ~ 9) button keys and two special service button keys (*, #), the Hangul to 10 Arabic numerals button keys A phonetic Korean keyboard system in which consonants and Hangul vowels are written simultaneously, comprising: a Hangul consonant keyboard unit in which Hangul consonants are arranged in the usual order on the ten Arabic button keys; Provided separately, there is provided a Hangul keyboard system for a phone, characterized in that made up of 10 Hangul vowels arranged in the usual order.

In the following, with reference to the accompanying drawings, a preferred embodiment according to the present invention will be described in detail.

1 is a configuration diagram of a keyboard system for 4x5 Korean input according to an embodiment of the present invention.

4x5 Korean input keyboard according to an embodiment of the present invention has a numeric key 101 and a special key (102, 103) in the existing phone keyboard. In addition, a key 101 for inputting Korean consonants and a key 104 for vowel input are separately provided, and a delete key for correcting an error during input and a next character key for completing a blank or syllable are provided. As shown in Fig. 1, 19 consonants including 14 basic consonants and 5 consonants are classified into 10 types according to their similarities and distributed to each of 10 numeric keys 1 to 0. The reason for the distribution of the 10 species is that of the 14 basic consonants, except the 4 vowels, that is, [a, b, c, d, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅎ] are independent sounds that sound relatively different. This is because the phoneme is a phoneme, and the four consonants and the five consonants are dependent phonemes that can be classified similarly to the corresponding consonants among the independent phonemes. As shown in FIG. The 10 numeric keys from 0 to 0 are distributed in the order shown in the Korean dictionary. Like the Korean keys on standard computer keyboards or the dial buttons on other telephone buttons developed earlier, 11 sub-consonants The key is configured to be input by pressing the keys in order. For the vowel, 6 vowel vowels (ㅑ, ㅕ, ㅛ, ㅠ) out of the 10 main vowels are included in order to allow the user to easily memorize and input them with skillful operation. Each key is allocated independently for. In addition, in this embodiment, each key is individually allocated to 'ㅐ' and 'ㅔ', which are frequently used short vowels among 11 parent sounds. These eight keys are added to the 12 dial buttons of the existing telephone. In addition, it is already considered to be an optimal location by ergonomic considerations and has been adopted for computer keyboards, and as a result, it is used as a consonant key set to be placed in a position familiar to users who use computer keyboards. Add to the right of the existing 12 keys.

If you want to input Hangul, enter it in phoneme order. If multiple letters are assigned to a key, the repeated press must be made within 0.5 seconds. If you make a mistake, press the Delete key to delete one phoneme and enter it again. To enter a space, press the next letter key twice.

Consonants are pressed as shown in the consonant keyboard 101, the first letter is written once, the second letter is pressed twice, the third letter is pressed three times repeatedly. Only when two or more consonants are assigned to a key is considered the start of one key syllable.

In the case of the collection keyboard 104, the same as above. In the case of a vowel key, there is no limit on the repetition press time. Among the vowels, 'ㅐ' can be entered as a combination of 'ㅏ ㅣ' and 'ㅔ' can also be entered as a combination of 'ㅓ ㅣ'.

2 is a configuration diagram of a keyboard system for 4x5 Korean input according to another embodiment of the present invention, which is the same as in FIG. 1 except that 'ㅐ' is a combination of 'ㅏ ㅣ' and 'ㅔ' is 'ㅓ ㅣ' It can be entered only by the combination of '. This method has the advantage that the user can reduce the time to find the keyboard because the size of the Hangul consonant keyboard and Hangul vowel keyboard is different.

3 is a configuration diagram of a 4x5 Hangul input keyboard system according to another embodiment of the present invention, which is the same as that of FIGS. 1 and 2, but the Hangul vowel keyboard 301 is arranged to be displaced from the Hangul consonant keyboard. This method has the advantage that the position of the Hangul consonant keyboard and Hangul vowel keyboard is different, so that the user can save time to find the keyboard.

As described in detail above, the present invention separates the Hangul consonant keyboard portion and the Hangul vowel keyboard portion to resemble common sense of the human being, thereby making it possible to easily input Hangul intuitively.

The technical spirit of the present invention has been described above with reference to the accompanying drawings, but this is by way of example only and not by way of limitation to the present invention. In addition, it is obvious that any person skilled in the art may make various modifications and imitations without departing from the scope of the technical idea of the present invention.
