Many
3D virtual environments (e.g., 3D Web sites) do not offer sufficient
assistance to (especially novice) users in navigating the virtual
environment, find objects/places of interests, and learn how to
interact with them. This paper proposes the adoption of guided
tours of virtual environments as an effective user aid and describes
a novel tool that provides automatic code generation for adding
such guided tours to 3D virtual environments developed using the
VRML language. In the second part of the paper, we informally
evaluate the proposed approach on a real-world application concerning
a 3D computer science museum (a complement to a real-world exhibition
focusing on the history of computer technology).
