Abstract：
The relationship framework between electroencephalogram (EEG) signals and subjective perception during pilots\' missions was established to improve pilots\' training efficiency and flight safety. Primarily, this study constructs a real flight scene through virtual reality (VR) and then obtains EEG data in simulated scenes. Researchers use VR technology to build a mission simulation room and then acquire EEG data from participants wearing EEG acquisition devices in the simulated room. The experimental process is divided into flight simulation and a questionnaire survey. Based on the participants\' EEG analysis, the researchers verified the changes of β rhythm under a high-difficulty operation mission. In addition, this study infers the mechanism of affecting pilots\' mental workload under high-difficulty operation by analyzing the correlation between subjective questionnaire results and β rhythms. The results showed that in the context of pilots performing flight missions in the aircraft space environment, the pilots\' mental load had the most excellent rhythmic relationship with the regions representing β rhythm. Therefore, a comprehensive experimental framework constructed in this study based on virtual simulation space to analyze the relationship between EEG and NASA-TLX subjective questionnaire provides a set of more accurate reference information for the design of a pilot training system based on pilot training efficiency and flight safety.
摘要：
为了提高飞行员训练效率和飞行安全,建立了飞行员任务期间脑电图(EEG)信号与主观感知的关系框架。首先,本研究通过虚拟现实（VR）构建真实的飞行场景，然后获得模拟场景中的EEG数据。研究人员使用VR技术建立一个任务模拟室，然后从模拟室中佩戴EEG采集设备的参与者那里获取EEG数据。实验过程分为飞行模拟和问卷调查。根据参与者的脑电图分析，研究人员在高难度手术任务下验证了β节律的变化。此外,本研究通过分析主观问卷结果与β节律的相关性，推断高难度操作下影响飞行员心理工作量的机制。结果表明,在飞行员在飞行器空间环境中执行飞行任务的背景下,飞行员的心理负荷与代表β节奏的区域具有最出色的节奏关系。因此,本研究构建了基于虚拟仿真空间的综合实验框架,分析了EEG与NASA-TLX主观问卷的关系,为基于飞行员训练效率和飞行安全的飞行员训练系统设计提供了一套更为准确的参考信息。
