Abstract

Background/Objectives: This paper presents a novel friendly and interactive Chinese character (Kanji in Japanese) learning system to enable elementary school students and foreign people living in Japan and to learn Kanji by an interesting and efficient way. Methods/Statistical analysis: By interacting with the network between the client application for students and the server application for teachers, teachers can grasp circumstances of education of all students in real-time. Findings: When students select and input characters they want to learn, the client application checks whether each stroke is unbalanced or not, and it is corrected if unbalanced. If there are no unbalanced strokes, a “Hanamaru” is displayed. On the other hand, the server application has two kinds of display modes, to display circumstances of all students and to display detail circumstances of each student, and teachers can switch them anytime. At the same time, the server takes statistics of points where each student is easy to make mistakes and saves them. So teachers can grasp circumstances and trend of all students. Moreover, pen speed and segment division are introduced in order to extract and correct local features, such as “tome”, “hane”, and “harai”, which were a weak point of previous system in spite of the important point in Kanji education. Improvements/Applications: Segment division is a method that refraction points of each stroke are extracted and each stroke is subdivided by these points and is used to correct “hane” and to distinguish between “ore” and “mage”. For both of them, the correction of local features can be realized and the close correction is enabled. Finally, by using the system actually, this system is evaluated whether it is useful to be able to write and memorize Kanji correctly and the interface is really friendly for learners. As a result, since many students feel interesting and useful to learn Kanji, it is clear that this system is useful for Kanji education. And the interface is also a high appraisal.
