在搜索和救援过程中，消防员需要在最短的时间和最少的信息下在一个不熟悉的空间找到路径。有效记忆和检索关键空间信息有助于降低风险和提高使命效率。虽然有证据表明，不同格式的寻路信息，包括地标，路线和调查，可以影响搜索和救援性能以不同的方式，消防员的认知过程的特点，有关不同的寻路信息格式的更深入的了解是探索较少。为了评估消防员在搜索和救援中的表现和认知特征，进行了虚拟现实（VR）中的消防员实验。招募消防员（n = 40）参加模拟救援任务。在查看不同格式的空间信息后，消防员被要求尽快在VR迷宫内找到三名受害者。任务绩效通过发现的受害者数量和花费的时间进行评估。消防员的凝视模式进行了分析，以评估他们的认知状态。结果表明，虽然在调查和路线条件下的认知负荷显着高于地标条件下（p < 0.001），决策涉及一个更有效的认知过程，与选择正确的路径在关键的航路点，如转弯决定必须作出。因此，这两种情况下的感知工作量和疲劳水平较低，寻路性能更好。与此相反，与地标信息，认知负荷水平一直很高，沿着增加的精神疲劳。研究结果揭示了一系列的认知功能相关的一个更有效的空间决策在搜索和救援。在未来，预计这些认知功能可以用来开发实时监测和预测模型的寻路性能。
During search and rescue, firefighters need to find paths in an unfamiliar space with minimum time and information available. The effective memorization and retrieval of critical spatial information can help reduce risks and increase mission efficiency. Although evidence has shown that different formats of wayfinding information, including landmarks, routes, and surveys, can impact search and rescue performance in different manners, a deeper understanding of the characteristics of firefighters’ cognitive processes related to the varying wayfinding information formats is less explored. To evaluate firefighters’ performance and cognitive characteristics in search and rescue, a firefighter experiment in Virtual Reality (VR) was conducted. Firefighters (n = 40) were recruited to participate in the simulated rescue task. After reviewing the spatial information in different formats, firefighters were requested to find three victims inside a VR maze as quickly as possible. Task performance was evaluated by the number of victims found and the time spent. Firefighters’ gaze patterns were analyzed to evaluate their cognitive status. The result showed that although the cognitive load under the survey and route conditions was significantly higher than under the landmark condition (p < 0.001), the decision-making involved a more effective cognitive process related to choosing the right path at critical waypoints such as where a turning decision must be made. Thus, the perceived workload and fatigue levels of the two conditions were lower, and the wayfinding performance was better. In contrast, with landmark information, the cognitive load levels were consistently high, along with increased mental fatigue.The findings reveal a series of cognitive features related to a more effective spatial decision-making in search and rescue. In the future, it is expected that these cognitive features can be used to develop real-time monitoring and prediction models for wayfinding performance.
