摘要
分析了计算机支持的协同工作 (CSCW )对协作和群体感知的要求 ,以共享白板作为CSCW的研究对象 ,介绍了一种共享白板的系统结构 ,论述了在此环境下共享对象的设计和协同控制策略 .对共享对象的应用服务和网络服务进行分层设计 ,协同控制采用令牌控制算法 ,解决了多个用户同时访问共享对象时的协同操作问题 。
On the basis of analyzing the demand of cooperation and group awareness in Computer Supported Cooperative Work, the topology of shared whiteboard is proposed, and the design of the shared object and cooperation control in this environment is described. In the design of the shared object layered method is used for application service and network service. Token control algorithm, which can resolve the problem that multi user can simultaneously approach the same shared object and provide flexible access control, is used in the cooperation control.
