Device and method for inputting Korean characters on touchscreen based upon consonant-vowel conversion, and electronic device using the same

摘要

A touch screen Hangul input method, an apparatus, and an electronic device using the same are provided. The Hangul input method according to the present invention comprises the steps of: (a) any one of the consonant input keys of the Hangul keyboard displayed on the touch screen is input as a consonant consonant; (b) vowel input keys that can be coupled to the consonant are activated on a touch screen; And (c) after one of the vowel input keys is input, activating a consonant input key of the Hangul syllable to which the vowel belongs or the initial consonant of the following Hangul syllables. Unlike the conventional method in which the input key is equally activated, the present invention selectively converts the active area of the input key based on the consonant-vowel according to the basic principle of Hangul, thereby avoiding an input error occurring in a narrow display environment. Can be significantly lowered. Furthermore, since the order of consonants-vowels and vowels can be optimized according to the Hangul input method, the input speed can be reduced and the input speed can be increased to significantly improve the Hangul input efficiency on the touch screen.
