How does spatial cognitive style affect indoor fire evacuation wayfinding in mobile virtual reality?

ABSTRACT In emergency situations such as fire evacuation, indoor wayfinding is a complex and challenging task that is closely related to spatial cognition and spatial ability. This study discusses the indoor wayfinding ability of evacuees from the perspective of spatial cognitive style. Spatial cognitive style can be divided into: landmark, route, survey (ordered from low to high). We measured the spatial cognitive style of participants, created a realistic virtual scene with a LiDAR scanner, and finally captured real behavior data using mobile virtual reality. The results show that people with a survey style can better extract information from an evacuation map and use it correctly, and they have a stronger sense of direction and cognition of the evacuation scene. People with a route or landmark style rely more on evacuation signs and following others to find their way and are more likely to lose their way in an emergency. These findings are helpful to explain the differences in wayfinding strategies and escape results of people in a fire evacuation.
