This position paper is aimed at highlighting the potential connection between Pervasive Systems and Collaborative Innovation. In particular, we discuss the architectural structure of an Innovation Catalyst supporting a collaboration methodology based on the Open Innovation paradigm. Our system is conceived for stimulating the collaborative dynamics of a team, exploiting all the information produced in the collaborative environment, including situational context, communication in team interactions, and personal behaviours. The results of our work can contribute to a more general understanding of the elements that catalyse collaborative innovation.
