空间信息的呈现界面对建筑火灾中寻路行为的影响

为了提高危机救援过程中团体内部与外部的空间共享效率,结合建筑火灾的动态建筑结构变化与人类空间信息的认知表征、空间信息的交互方式,设计了两种空间信息界面:静态朝向信息一致信息界面;动态朝向信息一致信息界面,探究动态环境中不同朝向信息对于寻路绩效的影响。通过Unity3D软件模拟实际空间环境的动态变化,采集虚拟环境中内部人员的寻路行为,并通过录像与访谈分析建筑内外人员的交互行为。实验结果表明:1)静态信息界面下寻路时间与路径更短,寻路过程中的错误路径更少,但交互行为更多。2)动态信息界面下寻路时间与路径更长,寻路过程中交互行为更少,但错误路径更多。研究结果可以为消防救援队伍的内外协同提供支持,提升救援效率。

Influence of Presentation Interface of Spatial Information on Path Finding Behavior in Building Fires

In order to improve the space sharing efficiency between the internal and external groups during the crisis rescue process,two kinds of spatial information interfaces are designed by combining the dynamic building structure change of building fire with the cognitive representation of human spatial information and the interaction of spatial information:static orientation information consistent interface,dynamic orientation information consistent information interface;cognitive style consistent information interface,to explore the impact of orientation information on way-finding performance.The Unity3D software is used to simulate the actual dynamic space environment and to analyze the way-finding behavior of internal personnel in the virtual environment,and the interaction between the inside and outside of the building is recorded through video and interview.The results show that:1)the way-finding time and travelling distance are shorter with the static information interface,and there are fewer errors in paths in the path-finding process,but the interaction behavior is more frequent;2)with the dynamic information interface,the path-finding time and path are longer,and the interaction behavior is less in the way-finding process,but the error paths are more.
