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