电子书画系统中毛笔笔型的模拟研究

对电子书画系统中毛笔笔型的模拟进行了初步的研究，根据力学原理经过大量的试验及书法家的实感要求，提出了毛笔压感数学模型，并根据毛笔楷书的字形及毛笔运笔中笔形变化的特点开发研究了较优的毛笔笔划模型，在此基础上，综合利用图形学，图像处理的相关理论和技术，实现了电子笔对真实毛笔的计算机模拟，并已取得了较好的阶段性效果，本文将对主要研究及实例进行介绍。     

A Context-Aware Infrastructure for Supporting Applications with Pen-Based Interaction

Pen-based user interfaces which leverage the affordances of the pen provide users with more flexibility and natural interaction.However,it is difficult to construct usable pen-based user interfaces because of the lack of support for their development.Toolkit-level support has been exploited to solve this problem,but this approach makes it hard to gain platform independence,easy maintenance and easy extension.In this paper a context-aware infrastructure is created,called WEAVER,to provide pen interaction services for both novel pen-based applcations and legacy GUI-based applications.WEAVER aims to support the pen as another standard interactive device along with the keyboard and mouse and present a high-level access interface to pen input.It emplolys application context to tailor its sevice to different applications.By modeling the application context and egistering the relevant action adapters,WEAVER can offer servicxes,such as gesture recognition,continuous handwriting and other fundamental ink manipulations,to appropriate applications.One of the distinct features of WEAVER is that off-the-shelf GUI-based software packages can be easily enhanced with pen interaction without modifying the existing code.In this paper,the architecture and components of WEAVER are described.In addition ,examples and feedbacks of its use are presented.     

面向视频会议的多功能手写笔白板系统及协同工作的研究

将电子笔的多功能手写模式引入视频会议．开发了模拟毛笔、钢笔、铅笔、浓淡笔、水溶笔、枯笔等自然笔特性的一系列电子笔功能．设计出了功能丰富、更具个性化表现力的手写电子白板系统，以满足人们网上技术交流所需要的视觉、听觉和手写三大自然习惯的要求，大大增强了现有视频会议的个性化交互性能、在多功能手写电子笔白板系统的基础上，还开发了相应的手写模式计算机网络协同工作(CSCW)的实验模型．并在实验室局域网和昆明理工大学校园网上进行了测试，效果良好，取得了阶段性成果．     

基于笔的人机界面和人机交互发展方向

1 引言随着计算机时代的到来和发展,基于笔交互的计算技术越来越受到人们的关注。早在1991年2月美国微软公司和GO公司分别发布了笔输入操作系统Win-dows for Pen,PenPoint,接着有Apple公司的New-ton,和General Magic的Magic Cap等,这些系统和产品的出现及发展大大推动了基于笔交互的计算模式和
