Abstract
We have developed a menu-selection-based Japanese input method for a pen device.To make a user inputs kanji-form text rapidly the system requires consonant sequence of the text. After that the user selects kanji-form candidates which are inferred by the system. However, there are some cases where kanji-form candidate explosion with certain consonant sequence, so we have implemented method for reducing candidates through vowel fixing. The user can input consonants and select kanji-form candidates fluidly using FlowMenu.Then we have evaluated the effectiveness of our input method by experiments with users.
