I: Initial (choseong)
M: Middle (jungseong)
F: Final (jongseong)
Korean Input Method
understand the Input Method for Korean language, we need to
understand the input method of
first. All of the Hanja is pronounced in a similar way to Hangul
and the Jamo is the basic building element for Hangul.
Hangul letter has three
(Initial Consonant), Jungseong (Middle Vowel), and Jongseong
section is represented by a few Jamo (lettter) (normally, 1 or 2,
Korean language is similar to Chinese and has the so-called Open(¶})-Short(»ô)-Close(¦X)-Curved(¼¼)
system for the middle sound (vowel). In fact, for modern
linguistic, the middle sound should be considered as the blending
of the consonant y/w and the vowels. The Sino-Korean linguistic
system is a phonetic system which groups the phonetic system into
several groups. It¡¦s natural for a small key input system.
There are only 4 ways of encoding. For
only group code
and order code
are used. For Hanja,
and shape code
are used. The definitions of those codes are listed below.
Jamo¡¦s Code Design
Hangul¡¦s Code Design
Hanja¡¦s Code Design
all Jamos, the shape code is 3, and we pick up two unit codes from
each of the first two letters. If there is only one letter, the
second letter code will be 0 or a jump code.
Hanguals, each word will have three individual letter codes, the
first letter code is for the choseong, the second one is for the
Jungseong, and the third one is for the Jongseong.
unit code of consonants, we define an order code for each letter
according to its appearance order on the keypad. For Jamos, each
basic consonant is a unit code. For Hanguls, each jamo is
assigned a code. We pick up unit codes for the Choseong (Inital)
and Jongseong (Final) as the two candidate code numbers, because
the major difference is on the Jongseong, not the middle sounds.
a vowel sound starting with ¡§w¡¨, it is assigned with ¡§2¡¨. For a
vowel sound starting with ¡§y¡¨, it is assigned with ¡§3¡¨. Jamo with
more than 1 letter is assigned an order code behind the one with
only one letter.
