The activation of the internet service and the spread of Korean wave have mass produced foreign netizens who are interested in Korean culture. As interest in Korean culture has increased, foreigners who want to study Korean language in order to understand Korean culture have increased rapidly in recent years There is a trend. For example, non-Korean users of the country refer to Korean subtitles such as Korean movies and music videos provided through the Internet, translate them into local languages, practice Korean characters and pronunciation, or more actively, It is common to learn Hangul through educational programs.

In general, Hangul is recognized as a very scientific, systematic and expressive language, but on the other hand it has been recognized as a language that is hard to learn and consumes a lot of time to learn. Therefore, it is very difficult for users of non - Korean countries to learn Hangul.

In particular, Hangul consists of at least one consonant and at least one vowel to form various letters and syllables, and at least one letter constitutes one word. Therefore, it is difficult for the user There is a side. For example, when a Korean word is recognized by an English-speaking user, it is difficult to intuitively recognize which pronunciation corresponds to a consonant, a neutral, and a bell forming each letter.

Therefore, non-Hangul users are quite difficult to input Hangul into the device using a general keyboard or the like. For example, Korean Patent Publication No. 2011-0105227 discloses a Hangul input device and an input method. The Hangul input device has a structure in which a basic consonant and a basic vowel are arranged so as not to overlap each other, but having a character input device corresponding to the basic consonant and one expansion device.
