模拟飞机降落过程中的眼动和认知研究

目的：对眼睛运动规律和大脑认知进行实验分析，研究被试者的注意力分配特点。方法：通过模拟飞机的降落过程，用眼动测量设备采集眼动数据并对眼动数据进行分析。结果：实验得到的眼动数据表明，被试者的注意力主要集中在飞机平显上的3个目标兴趣区域，被试者主要在目标兴趣区域之间进行视觉活动、分配和转换注意力。结论：被试者主要利用由上到下（top-down）的认知机制驱动眼动，分配注意力。眼动的结果使被试者获取了飞机飞行的情景意识。

Characteristics of Eye Movement and Cognition during Simulated Landing of Aircraft

Objective. To examine how the subject scans different parts of display panels and how the attention is distributed through the analysis of the eye movement principle and the cognition of the brain. Method. An experiment was conducted to simulate the airplane's landing course and eye movement data were recorded with eye movement measure system (EMMS). Result. There were three regions of interest (ROI) on which the subject's attention was concentrated. The subject's visual activity was active in the three ROIS and attention's shifting and distribution was between ROIS. Conclusion. Eye movement were driven by the top-down processing and the distribution of the attention. The consequence of the eye movement makes the subject maintain a continuous situation awareness.
