Abstract

People's emergency evacuation behavior is heavily reliant on spatial knowledge. Different spatial cognitive ways shape spatial knowledge differently. To investigate the effect of different cognitive ways on people's wayfinding performance in an indoor fire situation. The study used a virtual reality simulation of a shopping mall environment, and 128 participants were recruited for the experiment. The experiment divided the participants into six groups and placed them in two scenarios, one with and one without fire. This study also explored two other intervention behaviors to improve the participants' evacuation behaviors. The results showed that participants who used navigation had shorter walking distances and wayfinding times than those who used the You are here (YAH) map. Secondly, participants in the fire scenario walked longer distances and took longer to evacuate than those in the no-fire scenario, and they perceived successful evacuation to be more difficult. Thirdly, the intervention behavior effectively improved the participants' evacuation behavior and increased the efficiency of the evacuation. The leader's intervention was more effective in helping participants evacuate than the range intervention in this experimental setting. The findings may advance the understanding of human evacuation behavior and provide important practical implications for people's safety and emergency preparedness in shopping malls.

基于虚拟现实的模拟干预，改善不同空间感知模型下的紧急疏散情况

人们的紧急疏散行为在很大程度上依赖于空间知识。不同的空间认知方式会形成不同的空间知识。为了研究不同认知方式对人们在室内火灾情况下的寻路能力的影响。研究采用虚拟现实模拟商场环境，招募了 128 名参与者参与实验。实验将参与者分为六组，分别置于有火和无火的两个场景中。本研究还探索了另外两种干预行为，以改善参与者的疏散行为。结果显示，与使用 "你在这里"（YAH）地图的参与者相比，使用导航的参与者的步行距离和寻路时间更短。其次，与未发生火灾的情景相比，发生火灾情景下的参与者步行距离更长，疏散时间更长，而且他们认为成功疏散的难度更大。第三，干预行为有效改善了参与者的疏散行为，提高了疏散效率。在这个实验环境中，领导者的干预比范围干预更有效地帮助参与者撤离。这些研究结果可能会促进对人类疏散行为的理解，并为人们在商场中的安全和应急准备提供重要的现实意义。
