The war game is a significantly important means used by rescue workers to institute tactics in order to understand not only whether the rescue action can be feasible and successful, but also how the damage to personnel and equipment can be reduced. Traditionally, war games are conducted by using maps or sand tables; yet in this study, war games are conducted by applying an interactive electronic whiteboard. The tactical exercises in this study are performed by a computer system which can process the disaster site simulation, quick war games, accurate statistics, and other assessment including the number of soldiers, disaster relief personnel, vehicles, and logistics. By applying the interactive electronic whiteboard, the war-game simulation can use GIS to establish the simulated data obtained from GIS at the same time, making the simulation extremely realistic and spatial. During the simulation process, not only the earthquake range can be judged from the registration of buildings, but also the routes of evacuation and material delivery can be planned. In addition, in combination with the Google search system, the disaster calibration can be more accurate, and the disaster prevention performance of applying the interactive electronic whiteboard to simulate war games can be improved as well. The purposes of the establishment of the system by applying the interactive electronic whiteboard to simulate war games are to adopt the collective opinions and the analog training exercises at peace time to deduct the interaction with the disaster management personnel, simulate the various situations in actual disasters, determine the needs of resources and information, and develop the strategies of disaster response and recovery. Furthermore, this study examines the feasibility of the relief methods by verifying the war-game simulations with the application of the interactive electronic whiteboard and the field exercises, hoping to serve as an important reference for disaster management and disaster response. In this study, through the data compilation of the interviews with four key decision makers, it is found that the system can master the disaster information, immediately determine the decision-making judgment, replace the war-game modes at any time, and establish a variety of disaster prevention information and relief methods. According to the war-game simulation, the planned routes which are planned in the training can be used to conduct the rescue action and evacuate the public. As a result, the casualties and property losses can be reduced to a minimum, and the best performance of the application of the interactive electronic whiteboard in a war-game simulation can be also achieved.
