Abstract
In the paper, we present an application of Web3D technologies, X3D with X3DOM and HTML5, to enhance our e-learning platform DIEL. DIEL exploits the social translucence concept in order to create a virtual and dynamic learning space where avatars of community members can interact while implementing any social constructivist learning paradigm. While supporting collaborative learning communities, the addition of high-performance 3D graphics into a DIEL web page, without requiring any plug-in at client side, allows a complete and meaningful interaction with the e-learning services, that benefits the users' experience in the exploitation of proximity relationships with respect to other users and resources.
