Abstract : We describe a socio-technical system designed to train different organisations in emergency management during the preparedness phase. In this system, both humans and the system work together in building organisational context awareness. The system uses a normative multi-agent system and a tangible table for user interaction. Real time virtual feedbacks are used to draw users' attention to the validity of their actions with respect to the emergency plan. Feedback allows the actors to be aware of the other factors that impact the validity of their action (actions of other actors, environment etc.) and to identify the behaviour that is expected of them by the other organisations. The system is still in its prototype phase. Its behaviour is illustrated by example scenarios, showing that it is possible to support collaboration amongst distant actors, in a way that only relevant information is shown.
