The so-called “Kanbun,” the Japanese reading of the classical Chinese text, has been studied as a type of the classical Japanese in secondary education in Japan. In Kanbun the word order is changed based on symbols called “return mark,” which is converted into a Japanese reading. This change is often so complicated that it may cause phobias in learning for junior and senior high school students in Japan. Therefore in this paper, a visualization system of step-by-step change of word order is proposed, which recognizes the return marks on the classical Chinese text and visually superimposes the converted text beside the original one, in the use of the augmented reality (AR) technology. The proposed system is applicable to any Kanbun sentences so that it is expected to contribute to improved student understanding.
