  This paper presents an immersive virtual reality environment that can be used
to develop collaborative educational applications. Multiple users can
collaborate within the virtual shared space and communicate with each other
through voice. To asses the feasibility of the collaborative environment a
novel case-study concerned the education of a geography was developed and
evaluated. The geovisualization experiment scenario explores the possibility of
learning geography in a collaborative virtual environment. A user-study with 30
participants was performed. Participants evaluated and commented on the
usability and interaction methods used within the virtual environment.
