virtual spaces and two different tools as solutions for
supporting e-collaboration and multi-user
communication in web-based learning communities.
The first solution, called Virtual Conference, is
designed and implemented in the framework of the
VirRAD European project. It is a two-dimensional
space where participants represented by their photos
can use various e-collaboration tools. The second
solution, called EVE Training Area, is a threedimensional
space where participants, represented by
3D humanoid avatars, can use a variety of ecollaboration
tools. This paper describes the
functionality provided by both tools, compares them,
and proposes cases for exploiting each solution.1 aBouras, Christos1 aTsiatsos, Thrasivoulos1 aGiannaka, Eleftheria  uhttp://telematics.upatras.gr/telematics/publications/designing-virtual-spaces-support-learning-communities-and-e-collaboration
