Calligraphic Character Formation Based on the Simulation of Brush Writing Motion

本研究的目的是为毛笔字教育培训系统开发一种利用书法知识的计算机形成毛笔汉字的方法。我们已经开发了试点系统。该系统可以从在线手写字符输入中生成汉字骨架，并根据毛笔的形状、笔触和毛笔的动作模型形成书法字符，毛笔的笔迹风格主要取决于毛笔的使用方式。毛笔的书写技巧包括开始时的毛笔方向、毛笔的曲率、毛笔的转动以及笔划结束点处的刷子。我们根据前面提到的毛笔书写技巧对书法知识进行了修改。为了模拟真实的毛笔运动，我们设计了毛笔接触形式，即毛笔在书写平面(纸)上的形状作为毛笔触摸。该系统可以在画笔模拟期间控制该画笔触摸的大小和方向。该系统以骨骼为基础，在系统的数据库中模拟真实的毛笔笔迹运动和毛笔笔势。因此，系统用户(或学员)可以从该系统的书法知识库中学习毛笔笔触等毛笔书写技巧，我们认为该系统对于想要学习如何用毛笔写漂亮的日文字母的学生是有用的。

The purpose of the research is to develop a method of computer formation of brush-written Kanji (Chinese and Japanese) characters using calligraphic kowledge, which is for educational training system of brush writing. We have developed the pilot system. This system can generate skeltons of character from on-line handwritten character input, and formates the calligraphic character based on models of brush shape, touch on paper, and brush writing movement.The style of brush handwriting depens mainly on the way of using the writing brush. Brush writing skills include the direction of brush at the beginning, curvature, brush turning, and the brush-up at the termination poin in a stroke. We have revised the calligraphic knowledge according to the aforementioned brush writing skills. For simulating real brush movement, We devised the brush contact form that is the brush shape on the writing plane (paper) as a brush-touch. The system can control the size and direction of this brush-touch during the brush simulation. The system simulates the real brush writing motion and situation based on the skeltons in the data base of this system. Accordingly, the system user (or trainee) can learn the skills of brush handwriting such as the brush-touch from the calligraphic knowledge data base in this system.We consider that this system is useful for students who want to learn how to beautifully write Japanese letters by brush pen.
