Abstract:
Tablets, as well as smartphones and personal computers, are popular as Internet clients. A split keyboard is a software keyboard suitable for tablets with large screens. However, unlike other methods, the split keyboard has space in the center of the screen, which makes the part of the screen for displaying suggestions small and inconvenient. This paper proposes a Japanese input software keyboard that enables direct kanji input on a split flick keyboard. Once the user has mastered this keyboard, it allows the user to efficiently input Japanese text while holding a tablet with both hands. The paper presents an implementation of the keyboard on Android and reports the result of an experiment on its performance compared with existing methods. In addition, since direct kanji input generally takes time for users to learn, one of the authors by himself has conducted a long-term experiment to confirm the possibility of its mastery. For 12 months, both the input speed and the error rate have
gradually improved.
