We present a normative multi-agent design for computer-supported collaboration in the framework of sociophysical computing. An example application (RISK game) in the context of the TangiSense platform supports the proposed approach. Our work is driven under four complementary views: a systemic view, according to which various designing levels, from the physical infrastructure to the social level of human coordination are integrated in a single modelling, a normative view, in which consistency and coordination of action is ensured with respect to individual as well as collective systems of norms, a trace-based view, in which traces reflecting human activity and its compliance to the norms are registered and an agent-oriented view, according to which agents are meant to process, interpret and communicate information across distant tables.
