This paper reviews the literature about social and cognitive functions of spatial features used when collaborating in both physical and virtual settings. Those concepts come from various fields like social, cognitive as well as environmental psychology or CSCW (Computer Supported Collaborative Work). We briefly summarize the social and cognitive affordances of spatial features like distance, proxemics, co-presence, visibility or activity in the context of physical and virtual space. This review aims at grounding in an explicit framework the way human beings use space to support social interactions. This can be use as a starting point design efficient applications that take spatial context into account.
