A method for inputting Japanese letters using small number of symbols

摘要

PROBLEM TO BE SOLVED: To efficiently input Japanese Kana characters using a small number of pronunciation letter symbols.SOLUTION: Vowel symbols of "a, i, u, e, o" are assigned to five symbols among totally ten symbols including seven kinds of line segments, two kinds of circles and one kind of point. For symbols of consonant rows of "ka-, sa-, ta-, na-, ha-, ma-, ya-, ra-, wa-rows", a combination of two line segments among five line segments (left vertical line, upper horizontal line, right slanting line, left slanting line, lower horizontal line) forming a KANJI character sounding "ku" (which means "ward" in English") is assigned. Each of the line segments is inputted by designating two symbols from among symbols (7, 9, 1, 3) with which a keypad number is disposed. For example, a KANA character of "ka" (left vertical line, upper horizontal line, "") is inputted by successively selecting symbols of "1", "7", "9", "". Further, a vowel symbol is assigned to each of keypad numbers (e.g., "a" to "1"), respectively, a KANA character can be inputted by successively designating four keypad numbers (e.g., "1", "7", "9", "1" for "ka").
