Multipoint activity sharing services for fast prototyping of groupware applications

AbstractActivity sharing systems allow existing application programs to be displayed on multiple computers, while their users interact simultaneously with the shared applications. In this paper we introduce a new role for activity sharing: a platform to provide services for sharing visual information and managing multiple users' input. "Aware" application programs that share information and interact with several users concurrently can be developed efficiently using these services. Such programs have a high degree of interworking capability and can be prototyped quickly.
