DILEWA: the distributed learning environment without avatars

Multi-user VR systems are mostly aimed at social interaction, whereas exploitation of shared virtual environments for educational purposes has been largely ignored. We introduce the notion of tutor-based systems and consider the main differences between a tutor-based multi-user system and a social interaction system. In the proposed approach, one of the users is the tutor while the others represent auditors. This paper focuses on possible means for expressing a tutor's role including special auditor's operating modes supported by the mechanism of net-routes. Theoretical considerations have been tested on the DILEWA experimental system.
