基于视线追踪的三维模拟灭火救援培训效果评估
|
摘要
本文结合灭火救援指挥三维计算机模拟训练平台以及桌面式视线追踪实验系统,开展基于视线追踪技术的学员应急培训效果评估。首先开展眼动分析实验系统搭建与实验设计,采用Eyeso Ec80遥测式眼动仪对操作者模拟灭火救援时的眼动信息进行数据采集与处理。然后,开展失误行为的眼动特征提取研究,针对不同类别的认知状态,分别统计其在不同兴趣区域的注视时间并建立一步转移概率矩阵,最终得到典型失误模式的失误特征。
This paper combines the three-dimensional computer simulation training platform of firefighting and rescue command and the desktop line-of-sight tracking experimental system to evaluate the effectiveness of emergency training for trainees based on line-of-sight tracking technology. Firstly, the Eyeso Ec80 telemetry eye movement analyzer is used to collect and process the eye movement information of the operator when simulating firefighting and rescue. Further research on eye movement feature extraction of error behavior is carried out. According to different types of cognitive states, the gaze time in different regions of interest is counted and the one-step transition probability matrix is established. Finally, the error characteristics of typical failure modes are obtained.
