The paper introduces a research based on an innovative multi-user tangible interface system that aims to introduce an instrument to improve the response phase of the decision making process during risk management. The purpose is to set up and develop a decision support system in order to overcome some of the problems that are still causing inefficiency in the decision making process and to analyze the reactions of users upon the new introduced technology. The paper is divided into two main sections. The first part describes theories upon which the research project is based, explaining why and how a multi-user tangible interface can help collaborative communication during crisis response, the challenge, the chosen solution and the architecture. The second part describes how the presented solution will be tested to prove if the new system will be useful and accepted by users.
