| Synchronous collaborative work environments,
which are mainly based on video-confer-encing systems, suffer a
lack of human communication channels and social awareness because
mostly only audio, video, and joint editing of documents are
supported. Collaborative services such as floor control, session
control, and telepointers provide additional communication
mechanisms to support persons co-working through computers. We
propose a collaborative services model (CSM) for distributed
learning environments. Our model includes floor and session
control mechanisms and policies. Due to the realization of
collaborative services as operations on the model, no specific
network collaboration protocol is required. We present an
optimistic synchronization scheme which provides consistency for
the distributed model. |
