【摘要】：研究虚拟战斗机驾驶员飞行过程中涉及的监视、计算记忆、攻击和探测4项任务,通过改变工作的快慢节奏来影响脑力负荷,以正确反应率和反应时间来评价和分析被测试者在不同脑力负荷下对目标颜色、形状和位置的辨认情况,为人机界面设计目标编码及确定目标呈现时间提供科学依据;使用脑电图仪测量实验过程中被测试者的生理反应来评价脑力负荷与任务难度的关系。实验结果表明:在需要分配注意力的情况下,人对实验分别选取的3种颜色和形状的辨认不受脑力负荷大小的影响,脑力负荷大小影响人对不同位置的目标辨认;人的目标辨认显著受到目标呈现时间的影响,目标呈现时间越长,反应时间越长;脑电图在一定程度上波的频率和高振幅波能反应脑力负荷大小。
[Abstract]:To study four tasks involved in surveillance, computational memory, attack and detection in the flight of a virtual fighter pilot, and influence mental load by changing the speed and slow rhythm of the work. The correct reaction rate and reaction time were used to evaluate and analyze the recognition of the target color, shape and position under different mental loads, which provided scientific basis for the design of target coding and the determination of target presentation time. The relationship between mental load and task difficulty was evaluated by using electroencephalogram (EEG) to measure the physiological reaction of the subjects in the experiment. The experimental results show that the recognition of the three colors and shapes selected by the experiment is not affected by the size of the mental load, and the size of the mental load affects the recognition of the target in different positions. The longer the target presentation time, the longer the reaction time, and to some extent, the frequency of EEG and the high amplitude wave energy reflect the mental load.
