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

Research of Electronic White Board with Digital Tablet for CSCW in Net-Meeting

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 。

What makes this research different is that it mainly introduces digital tablet into the videoconference system and its special feature is exploited as the simulated brush pen, pen, pencil, shade-pen, watery pen and withered-pen.Therefore, the videoconference equipped with digital pen whiteboard system designed has more functions and more expressive capability, which is satisfied to people's natural custom of vision、hearing、writing in communication and the individualized communication of videoconference is greatly improved. Based on the above results, the experimental prototype for Computer Supported Cooperative Work (CSCW) in the corresponding tablet module is developed. As a stage production, the system has been tested on LAN and campus network of Kunming University of Science and Technology and achieved good results.
