Abstract

Synchronous collaborative environments can provide an identical visual and operable working area among geographically separated participants. There are two basic approaches for providing a shared workspace. They are collaborative-aware approach and collaborative-unaware approach. Since the second approach allows single-user applications to be reused, most users choose to use it. Our work is based on the collaborative-unaware environment. This paper describes the design and implementation of some transparent synchronous collaborative tools. They are: (1) the latecomer support for Java applications, Java applets and JMF players (2) the client synchronization to minimize data transmission latency and (3) the lightweight multi-session support to let different collaboration groups work at the same time. These tools optimize existing transparent synchronous collaboration systems and make them more realistic, more complete and more generic.
