What is TUT-CODE?

TUT-CODE is a high-speed Japanese input method. we can type Kanji directly by TUT-CODE.

If you want to type 「愛」, touch the "C"-key and "N"-key continuously on qwerty keyboard.

＝愛

If you want to type 「夢」 , touch the "O"-key,"H"-key, and "G"-key continuously on qwerty keyboard.

=夢

The mention above, TUT-CODE have 725 Kanji(using 2-strokes) and 1,800 Kanji(using 3-strokes). It is thought that by nearly 700 kinds of Kanji, we can express about 90% of whole daily Kanji(in newspaper) statistically.  In TUT-CODE, 725+1,800 Kanji have been chosen .

The rate of Kanji in a document

I researched the rate of Kanji in a document using internet news site(Yahoo Japan in oct.2003) for reference. I collected about 100,000 letters(Kanji) from various category, politics, economy, society, culture, art, science, education, etc. at random. The rate of 725 Kanji, and the rate of 725+1,800 Kanji are as follows.

In this case, 725 Kanji can be expressed little less than 90% of all, and 725+1,800 Kanji can be expressed almost all.

Why can we type Kanji directly?

Many skilled English typists don't recognize each letter in typing. They recognize as group, the syllable, the word, or the sentence. And they can type quickly. Similarly it is natural for us to recognize Kanji as group.

Why can we type quickly?

Why can we type quickly by TUT-CODE rather than the Kana-Kanji conversion? I show the cause of this point, comparing different 2 way(one is TUT-CODE, other is the Kana-Kanji conversion).

The typing using TUT-CODE

The typing using Romaji/Kana-Kanji conversion

These are quite obvious. We can type smoothly by TUT-CODE, not needing the conversion to Kanji and not needing to choose from list. (Actually the how to appear Kanji is always changed by system in the Kana-Kanji conversion)
