The way-finding behaviour and response during a fire emergency in a virtual environment (VE) was experimentally investigated. Forty participants, divided into two groups, were required to find the emergency exit as soon as possible in a virtual hotel building because of a fire escape demand under condition 1 (VE without virtual fire, control group) and condition 2 (VE with virtual fire, treatment group). Compared to the control group, the treatment group induced significantly higher skin conductivity and heart rate, experienced more stress, took longer time to notice the evacuation signs, had quicker visual search and had a longer escape time to find the exit. These results indicated that the treatment condition induced higher physiological and psychological stress, and had influenced the escape behaviour compared to the control group. In practice, fire evacuation education and fire evacuation system design should consider the response characteristics in a fire emergency.
通过实验研究了虚拟环境（VE）中火灾紧急情况下的寻路行为和反应。40名参与者被分为两组，由于在条件1（无虚拟火灾的虚拟环境，对照组）和条件2（有虚拟火灾的虚拟环境，治疗组）下有火灾逃生需求，他们需要在虚拟酒店建筑中尽快找到紧急出口。与对照组相比，治疗组的皮肤电导率和心率显著更高，经历了更多的压力，注意到疏散标志的时间更长，视觉搜索更快，找到出口的逃生时间更长。这些结果表明，与对照组相比，治疗条件引起了更高的生理和心理压力，并影响了逃生行为。在实践中，火灾疏散教育和火灾疏散系统设计应考虑火灾紧急情况下的反应特征。
