The present invention relates to a Hangul keypad, and more particularly, to a Hangul keypad that can improve the consonant perception and character input by arranging short vowels around the consonants with high frequency of use in a four-row, three-column keypad. It is about.

In general, a device for inputting and displaying characters includes a computer or typewriter, an electronic notebook, a PDA, a mobile phone, and the like. However, in the case of the computer, the typewriter, and the electronic notebook, a plurality of keys corresponding to the letter's letter must be provided to input a character, and each of these keys is assigned a specific type of code to form a character by a combination thereof. Done.

As such, a device for inputting and displaying characters must have a keyboard having a plurality of keys arranged thereon, and in order to input and display characters (Korean or English characters) in a desired form, at least 24 characters in Korean and 26 characters are required. Since a letter key and a specific key must be provided, it is difficult to miniaturize by a plurality of keys and cannot be carried.

In recent years, the rapid growth of small character input devices such as PDAs, electronic calculators, and mobile wireless communication terminals (mobile phones) have increased the need for text input for additional service functions. It is happening.

However, since most of the devices using the text input as an additional service are small, the keypad is also small, so that at least two phonemes are arranged on one key button in order to input 26 Korean characters within the limited keypad. .

Therefore, the letters of the alphabetical arrangement are inputted one by one like the keyboard of a computer or typewriter, and the size of the keypad is small. The method of use is not different from a computer system. Rather, two or more phonemes arranged on one key button are used. If you are not familiar with it, you have difficulty entering.

Thus, in order to display all 26 consonants of Hangul within a limited keypad, the existing Hangul consonants arranged in accordance with the basic consonants composed of consonants a, b, ㅁ, ㅅ, ㅇ The characters are input based on Cheon (·), 지 (ㅡ), and phosphorus (ㅣ) samjae. The Korean vowel input can be pressed in order of the vowel stroke order. In other words, press "는" in sequence "·", and in the case of "ㅕ", press "" "twice and then press" ㅣ ". "Press twice in a row.

In this way, the Korean alphabet can be solved with only three vowel keys, and the consonants are evenly arranged to represent all Korean input. However, in the above case, the number of consonants is reduced since the consonants are evenly arranged. In the case of vowels, that is, positive vowels (ㅏ, ㅗ), vowels, and double vowels in the vowels have the disadvantage of requiring excessive input strokes.

In addition, since the Korean alphabet uses only 10 keys out of 12 keys, the three keys have consonants due to overlapping consonants, resulting in a friction between each other. Considering that the long fingering distance is long enough to give a problem to hand.

And Naraggle uses two keys for positive vowel (ㅏ, ㅗ) voice vowel (ㅓ, TT) keys, but 12 keys are used for the whole. The same is true with only four keys.

An object of the present invention is to improve consonant vowels and consonants and vowels in the 4x3 keypad to improve the cognitive ability of characters and anyone to input text easily.

Another object of the present invention is to improve the character input speed by reducing the number of key inputs according to the combination of vowels in the character input by arranging the consonants in the upper and lower, high frequency consonants and vowels in the middle of the 4x3 keypad. .

In order to realize the above object, the present invention arranges consonants a, b, c. D in the number 1, 2.3 keys on a single line on a 4x3 keypad, and applies ㅁ, ㅂ, ㅅ, 에 to four special characters and numbers. The most consonant consonants are arranged on the 5th key of 2 rows, and the numbers 4,6,7,8,9 on the 2nd and 3rd rows are the vowels (ㅜ) It is characterized by consisting of (ㅏ) (배열) (배열) arranged in each arrangement.

The consonants (a, ㄷ, ㅂ, ㅅ) are arranged in the numbers 1, 3, and the special characters *, 0 and # on the first line, respectively.

Therefore, according to the present invention, the consonants and vowels are placed on the 4x3 keypad at a location where the consonants and vowels are frequently used, so that the user can easily recognize them and at the same time, separate them into convenient positions, thereby making it easier to input characters. Of course, it is possible to improve the character input speed by reducing the number of input strokes.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
