7 virtual environments

From a user perspective, virtual environments offer the most advanced interface to multimedia information systems. Virtual environments involve the use of (high resolution) 3D graphics, intuitive interaction facilities and possibly support for multiple users.

In this chapter, we will explore the use of (desktop) virtual environments as an interface to (multimedia) information systems. We will discuss a number of prototype implementations illustrating, respectively, how paintings can be related to their context, how navigation may be seen as a suitable answer to a query, and how we can define intelligent agents that can interact with the information space. Take good notice, the use of virtual environments as an interface to information systems represents a major challenge for future research!
