Abstract-In this paper we analyse the theoretical underpinnings underlying collaboration in virtual environments and propose a 3D Virtual World (VW) approach to the construction and facilitation of communities of practice within the context of social innovation. Although connected networks can emerge from 'flat' 2D Social Networks, while face-to-face meetings have been proven successful to undertake innovative entrepreneurial ventures, the 3D VW approach possesses affordances that can be exploited to augment the experience. We propose a model for a 3D Virtual World, as part of the Euro SouthHub project, that facilitates the social innovation experience through collaboration and the setting up of communities of practice, using the Virtual Environment to move towards producing solutions for a better physical world.
