In general, a device for inputting and displaying characters includes a computer or typewriter, an electronic notebook, a remote controller, a computer game, 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 electronic organizers, remote controllers, computer games, PDAs, electronic calculators, mobile wireless communication terminals (mobile phones), and the need for text input for additional service functions is increasing day by day. There is a lot of research into character input.

However, since most of the devices using the text input as an additional service are small, the keypad is also small, so that 29 characters of Korean characters, consonants (consonants (14) + vowels (10) + twin consonants (5)) are limited. In order to input the character of), at least two or more phonemes are arranged in duplicate on one key button.

Therefore, there have been various forms of research and presentation to express all 29 Korean consonants (including 5 consonants) in 10 keys of a limited keypad.

First, the method of combining vowels {inputs characters based on Cheon (·), Ji (ㅡ), and phosphorus (ㅣ) Samjae}.

Second, the phoneme combination method {a, b, ㄹ, ㅁ, ㅅ, ㅇ six basic consonants consisting of consonants and function keys (capture key and parallel key) to enter the characters}-aka naragle.

      The following is a description of the vowel input of Korean characters, Cheonji.

Cheonjiin Hangul has the biggest advantage of solving 21 single / composite vowels with only three vowel keys, but in the case of positive vowels (ㅏ, 음성), vowels (ㅘ ㅝ ㅙ ㅞ) It has the disadvantage of requiring 3 round trips and an excessive input stroke.

 In addition, since the Korean alphabet uses only 10 keys out of 12 keys, there are disadvantages in that three pairs of consonants generated when battering the same key with two pairs of consonants (ㄴㄹ) (ㅅㅎ) (ㅇㅁ) are intrinsically rubbed. Also, it is easy to make a typo because it is confusing to reciprocate the heavy input stroke and 3 keys, which are celestial. Therefore, the character input speed is slow, as well as the long fingering distance has a problem that give a hand.

         Below is a description of the Hangul Hangul (vowel) collection.

 Naraggle uses four vowel keys, six consonant mute keys, and two function keys, namely the capture key and parallel key (* #), making it difficult to learn with user-friendly input. The consonant combinations must be combined, and even complex vowels have a disadvantage in that the incidence of typos is high due to the large fingering distance and eye movement. However, since the consonant is combined using the stroke / byeongseo key, the lack of consonant friction is also the biggest advantage of Naragle.

On the other hand, the cross-dial keypad proposed by the present invention connects 12 Shiki (North), 6 Shiki (South), and 3 Shiki (East) and 9 Shiki of the watch based on wheels and watches known to mankind. 21 characters input keys are arranged based on the basic structure, and simple and balanced character arrangement, frequency of use and fingering distance, etc., and the friction of two consonants (b d, ㅇ, ㅅㅁ) By arranging the character input keys to solve the trivial consonant of three pairs of consonants, improve the cognitive cognition, and facilitate the input of characters, the characters / vowels are quickly reminded and You can type quickly and easily.
