基于VR实验的老年人照料设施交通空间寻路绩效研究

Wayfinding Performance Review of Traffic Space in Nursing Home Based on Virtual Reality Experiments

为了进一步研究我国老年人照料设施交通空间的环境特征对老年人寻路行为的影响,采用VR实验方法,在6个照料设施典型平面中设置24项虚拟寻路任务,以受试者模拟新入住照料设施或患阿尔茨海默症等对环境具有陌生感的老年人,获取虚拟寻路移动坐标信息、实验过程录屏、问卷与主观感受等寻路数据,分析被试者在寻路任务中的行为特征并衡量寻路绩效指标(实际轨迹长度、路径比率、环境线索得分和寻路任务失误次数),揭示交通空间的平面布局及视觉环境因素与寻路绩效的关联,在此基础上提出建筑布局和环境线索两个层面的寻路支持设计策略。

Using the VR experimental method,24 virtual wayfinding tasks were set up in the typical planes of 6 care facilities,and the subjects simulated the elderly who were newly admitted to the care facility or suffering from Alzheimer's disease and other elderly people with the unfamiliar environment.Moving coordinate data,wayfinding process recordings,questionnaires,and subjective feelings were collected,and the subjects'wayfinding behavior characteristics,as well as wayfinding performance indicators,were analyzed.The relationship between the visual environment factors of traffic space,such as floorplan layout,and wayfinding performance was then revealed using statistical analysis.Based on these,some design strategies for wayfinding support about space layout and environmental cues were proposed.
