学校防灾教育的现状涉及到不认识教育必要性的人（即没有内在动机的人，远离灾害教育）。为了促进防灾教育，我们提出了一个以火灾为重点的虚拟现实防灾培训系统。该系统有三种模式，分别是VR疏散演练、VR消防训练和VR综合训练。首先，用户可以通过虚拟现实疏散演练来学习火灾情况下的疏散方法。其次，用户可以通过体验灭火方法，进行VR消防培训。最后，在一般培训中，用户可以在疏散和消防演练中获得的知识的基础上，进行火灾情况下的试训。我们将参与者分为两组进行了实验：一组使用现有的使用教材的方法进行训练，而另一组使用提出的方法进行训练。随后，我们进行了VR综合培训和IMMS评估，以调查该系统是否比现有教学方法有所改进。结果表明，该系统在关注度（+1.58）、相关性（+0.7）、置信度（+0.2）和用户满意度（+2.16）方面取得了较好的效果。此外，在使用该系统训练的人群中，玩家在VR综合训练期间的平均疏散风险为-6.45 p，灭火启动时间缩短-10 s，用户可以安全快速地应对灾害。
The current state of disaster prevention education in schools involves people who are unaware of the necessity of education (i.e., people with no intrinsic motivation and disaster education away). To facilitate disaster prevention education, we propose a virtual reality (VR) disaster prevention training system focused on fire disasters. This system has three modes, namely, VR evacuation drills, VR firefighting training, and VR comprehensive training. First, VR evacuation drills can be learned by users by gaining experience of evacuation methods in cases of fire. Second, users can undergo VR firefighting training by gaining experience of extinguishing methods. Finally, in general training, the users can experience trial training in case of fires on the basis of the knowledge gained in the evacuation and fire drills. We conducted an experiment by dividing participants into two groups: one group was trained using existing methods employing teaching materials, whereas the other was trained using the proposed method. Subsequently, we conducted VR comprehensive training and an IMMS evaluation to investigate whether this system demonstrates an improvement over existing teaching methods. The results indicated that the proposed system achieved better results in terms of attention (+1.58), relevance (+0.7), confidence (+0.2), and user satisfaction (+2.16). Furthermore, for groups trained with the proposed system, the average evacuation risk of the player during VR comprehensive training was -6.45 p, the fire extinguishing start time was -10 s lower, and the user could act against disasters safely and rapidly.
