||The computer industry is on the brink of a new era. The future is not a solitary PC, but a diverse set of smart, cooperative devices interacting not only with its end users but also with each other while fully integrated in their environment. The interaction with these systems are multimodal where the tools become extensions of the human sensor and motor systems supporting the end users? cooperative execution of actions while trying to solve problems. The computer is thus no longer a system that just determines something by mathematical means, brings order (Fr. "Ordinateur"), handles data (Swe. "Dator"), count information (Hun. "Bilgisayar"), or is a machine full of knowledge (Fin. "Tietokone"). It is rather an infrastructure for multimodal human-computer interaction and cooperation. However, are we as designers equipped to meet the rapid evolution within the computer industry? We suggest that we need to find a way to minimize the gap between analysis and design to be able to continue delivering optimized and satisfactory systems to our customers and end users at a reasonable price. My research is being conducted in the context of ATOL (Aeronautics Technico-Operational Laboratory), a joint enterprise between TELECOM Bretagne, Thales Group and Ecole Navale (the French Naval Academy), where we study multimodal computer-supported cooperative work (CSCW) within the context of maritime surveillance missions.
