Abstract:

In order to address the limitations of traditional earthquake rescue training disaster site, including low simulation fidelity, poor safety, high costs and inadequate quantitative monitoring, this study developed a standardized, full-process earthquake emergency rescue training system using VR technology based on the Unity 3D engine, creating a virtual training scenario for earthquake disaster scenes. While systematically improving rescuers' tactical skills and practical abilities, the system enables quantitative measurement of training effectiveness. On one hand, this paper describes the model building, scene design, functional modules, and interactive design process of the earthquake emergency rescue training system. On the other hand, through pre-test and post-test control experiments, participants' performance is evaluated in terms of theoretical knowledge of earthquake disaster rescue, operational skills, and rescue strategies. The results show that subjects receiving training through this system significantly outperformed the traditional training group in both immediate knowledge acquisition and two-week knowledge transfer efficiency (P < 0.05^*, Cohen's d = 1.0), particularly in skill and strategy learning outcomes (P < 0.05^*, d = 1.23). Meanwhile, subjective experience evaluations confirmed high satisfaction ratings from subjects, corroborating the system's practical efficiency in knowledge transfer performance (P < 0.01^**, 1.1 ≤ d ≤ 3.9).
