文档介绍：浅论基于JAVA的共享白板的设计
摘要
的迅速普及,计算机技术进入了以网络为中心的时代。在计算机网络的支持下。地理上分布的人们需要协同工作。因此计算机支持协同工作(CSCW)应运而生。人们希望借助协同工作环境以“你见即我见”的方式进行交互。而电子白板作为计算机支持协同工作(CSCW)中的一个重要的图形交互工具,使处于不同地点的用户通过计算机可以实时的进行图形交互,用户简单快速地实现协同工作,业务处理过程,迅速适应市场的变化,从而获得更好的经济效益。
本系统将CSCW与Java技术相结合,采用Java语言中的Socket网络编程技术,实现了客户端与服务器端之间网络底层的链接和信息的交换,用C/S计算机模型设计并实现了一个基于Java的电子白板系统,增加网上绘制图功能,弥补了纯文本非实时交流的不足,简化了网络中的技术细节,方便可行。

The Design and Implementation of Oriented CSCW Shared Whiteboard
Abstract
Along with rapid popularity of , computer e work puting epoch. People who are in geographically distributed locations need to collaborate with each other, so puter Supported Cooperative Work (CSCW) springs up. People hope interacting with each other using the WYSIWIS(What You See Is What I See) mode in CSCW environment. The shared whiteboard is the most important tool of graphic interaction in CSCW, which helps people locating different areas to interact each other with graphics puters. The customers carry out a work, deal with the process of business and adapt a series of variety of the market in a brief and quick way .Then a better and economic performance is acquired.
This bines CSCW with Java technology and carries out the links of the low layer of works and switch of the information among the clients and severs using the socket programming technology with java. The design and implementation of the shared whiteboard system based on java adopting the C/S module puter increases the online drawing function, makes up the shortage of pure text of the no real time and predigests the details of technology work. So the system is very useful for us.
Key words: share whiteboard; CSCW; Java; Socket; Client/Server(C/S)
