Kanji Factory - Development of Japanese Language Learning System based on the Observation of Handwriting Behavior

本研究的目的是开发出适合外国人的日语学习系统，日语中含有汉字和平假名、片假名，比使用字母的欧洲语言具有更复杂的结构。通过手写文字的练习对于学习这样复杂的日语其实是有效的。在本研究中，我们利用联机文字辨识技术建构日文书写方法学习系统。我们建立了包括日常使用的汉字、平假名和片假名在内的约2000个字符的手写参考字符数据库，包括字符的书写顺序。该数据库还包含“母鸡”、“筑”等偏旁部首和公平书写规则。学习者使用输入板以手写输入练习字符。该系统检测和评估的字母形状，笔画形状，笔画顺序和输入字符的书写速度。在评估输入的字符后，系统将具有正确字符的书写方法的指令返回给学习者。该系统是在Web上开发的。在Web服务器上编写了输入字符的评价模块和参考数据库。学习者可以从输入单元的Web客户端练习如何正确地写日语。

The purpose of this study is to develop the Japanese learning system for the foreigner, Japanese that contain the Chinese character and hirakana, katakana, have the complicated structure further than the Europe language using the alphabet. The practice through the handwriting character actually is effective for acquiring like this complicated Japanese. In this study, we construct Japanese writing method learning system using the on-line character recognition technique. We construct the handwritten reference character database of daily use Kanji character, hirakana and katakana about 2000 character including the writing order of the character. The radicals such as "Hen", "Tsukuri" and the fair handwriting rule are also contained in this database. The learner inputs the practice character in the handwriting using the tablet. The system detects and evaluates letter shape, stroke shape, stroke order and the writing speed of the input character. After evaluating the input character, the system returns the instruction on the writing method with the right character to the learner. This system is developed on Web. We prepare evaluation module of the input character and the reference database on Web server. The learner can practice how to write Japanese properly from Web client of the input unit.
