Title
Automatic Management of Sessions in Shared Spaces
Abstract
In this paper we propose a session model suited for cooperative work in shared spaces such as virtual 3D spaces. Our session model aims at structuring interactions on shared objects, without requiring explicit session preparation. Sessions are rule driven: accessing objects triggers automatic session creation, deletion or merge. Automatic session management enhances the dynamics of cooperation: users are not constrained by predefined schemes and they can join and leave easily by accessing shared objects (e.g. editing documents, moving to locations in virtual spaces). Our session management model is well suited to coincidental encounters and cooperation in shared spaces. Moreover, sessions promote rules for shared access and help users to get a clear perception of the ongoing interactions. As cooperative applications are distributed by essence, maintaining data consistency is a difficult issue. Our session model helps to define groups of objects which can then be used by a distributed consistency management service. In this paper we detail our session model and its rules, together with an algorithm for automatic session management. We conclude with a scenario of an encounter in a virtual space.
