User Guidance in Virtual Worlds

  • Conference paper
Communicating with Virtual Worlds

Part of the book series: CGS CG International Series ((3056))

Abstract

We introduce a software architecture which supports user guidance in virtual worlds. The user guidance is realized with task-oriented agents communicating with users through a command-based dialogue interface. The agents use an application independent toolbox, the hyper-renderer, for evaluating information that is calculated during the rendering process, but usually not provided for use outside the rendering program. As an application, we describe a prototypical exploration agent which guides visitors of a virtual building to any destination inside the building. The visitor is navigating independently, while the agent presents sign-posts at appropriate locations. In our implementation, we used symbolic visibility preprocessing. Example frames of an interactive walkthrough are included.
