A Mixed Reality-based Fire Evacuation Drill System

Regular evacuation drills from fire have the advantage that many people can participate at the same time. However, during training, you just walk down the corridors and passageways as usual, and it lacks a realistic feel, especially with flames and smoke. Since the number of facilities with realistic flames and smoke is limited, it is difficult to conduct drills with such realities in schools and workplaces. In this paper, we propose a system that uses mixed reality (MR) technology to simulate fire and smoke during an evacuation drill at a school or workplace. The proposed system uses a transparent head-mounted-display (HMD) to move through the real world, so that the system provides trainees with a highly realistic image of flames and smoke superimposed on the evacuation route. In addition, the appropriateness of the evacuation action is assessed by recording the route and time of the action, and the results are presented to the trainees at the end of the exercise to improve the effectiveness of the exercise.
