The recently launched TATIN-PIC Project at the University of Technology of Compiègne is a multi-modal collaborative work environment for teams performing preliminary design. In this paper, we present the design and reasoning for the plans of our groupware system. Effective preliminary design teamwork requires alternating stages of discussion, exploration, and diverging ideas, coupled with stages of focus, decision-making, and convergence. We believe providing a design team with an interactive tabletop can fulfill the first role and an interactive whiteboard can satisfy the second. Users will be able to switch seamlessly between the two, shifting content from one to the other when necessary. In this paper, we begin with a discussion of the advantages and characteristics of preliminary design. We continue with a review of the state-of-the-art in interactive, board-sized surfaces. We discuss experiments and results from TATIN, the precursory project to TATIN-PIC. Finally, we introduce our plans for an innovative work environment. Its multi-agent software architecture will be capable of supporting voice commands, tablets, smartphones, and personalized assistants capable of ontological reasoning about the project work.
