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

我们开发了一个实时训练系统，使用字符识别技术来获得良好的日语字母写作技能。在日本，笔迹不仅要显示其字面意义，还要显示作者的个性和感性。该系统以基于规则的范式存储手写日文字符数据库和书写技能知识。当用户用钢笔在书写板上书写/输入字母时，系统可以监控用户的书写方式，并可以评估用户的书写技能程度，如笔画顺序、书写速度、字母形状、子模式分配等。每次用户写完一个字母，系统就会根据用户的写作水平，在显示屏上直观地画出一个修改后的字母，显示需要修改的地方以及如何改进，使其更美观。这个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.
