Penmanship CAI System for Japanese Learning Based on On-Line Observation of Handwriting

我们开发了一个利用字符识别技术获得良好的日语字母书写技能的实时训练系统。在日本，笔迹不仅要显示字面意思，还要显示作者的个性和情感。该系统以基于规则的范例存储手写日语字库和书写技能知识。该系统可以监控用户在用笔在书写板上书写/输入字母时是如何书写的，并可以评估其书写技能的程度，如笔顺、书写速度、字母形状和子图案的分配。每次用户写完一个字母，系统就会根据他的书写技巧的程度，通过在显示器上直观地画出一个跟随他输入的字母的更正的字母，来显示需要更正的内容以及如何改进他的字母，使其更漂亮。该系统对正在学习日语的外国学生也很有用。

We have developed a real time training system for acquiring good writing skills of Japanese letters using character recognition techniques. In Japan, a handwriting is supposed to reveal not only its literal meaning but also the writer's personality and sensibility. This system stores a handwritten Japanese character database and the skill knowledge of writing in a rule based paradigm. The system can supervise how the user writes his letter while he is writing/inputting letters on the writing pad with a pen and can evaluate the degree of his writing skills such as stroke order, writing speed, letter shape, and allocation of sub-pattern. Each time the user finishes writing a letter, according to the degree of his writing skill, the system shows what to be corrected and how to improve his letter for more beautiful one by visually drawing a corrected letter which follows his input letter on he display. This system is also useful for foreign students who is learning Japanese language.
