合理的装甲车辆智能化与信息化设计对于降低乘员脑力负荷水平、提高乘员综合作战效能具有重要意义。为探讨智能化设计与信息加工通道复杂度对装甲车乘员脑力负荷的影响,基于某新型装甲车仿真平台,面向装甲车指挥员典型作业任务,选择20名被试人员开展了乘员脑力负荷影响因素综合实验。实验结果显示:高智能化任务相较于低智能化任务具有更低的美国国家航空航天局任务负荷指数量表得分、alpha波段的绝对功率、任务误操作率以及更高的平均扫视峰值速度;视听双通道任务相较于视觉单通道任务具有更高的美国国家航空航天局任务负荷指数量表得分、theta波段的绝对功率和平均瞳孔直径。研究结果表明:高智能化设计条件下乘员的脑力负荷显著低于低智能化设计条件,人机系统的自动化操作与智能人机交互模式可有效降低高信息需求下乘员的工作负荷;视听双通道加工条件下乘员的脑力负荷显著高于视觉单通道加工条件,但使用视听双通道信息加工模式在多任务需求下有利于维持乘员作业绩效;不同生理测量指标对于脑力负荷影响因素具有差异化的敏感性和诊断性。 |

Rational intelligent and information design of armored vehicles is of great significance to reduce the mental workload and improve the effectiveness of armored vehicle occupants. In order to investigate the influences of intelligent design and complexity of information processing modality on occupant mental workload, and based on a new armored vehicle simulation platform, 20 subjects were selected to carry out a comprehensive experiment on the influencing factors of occupant mental workload according to the typical operational task of armored vehicle commander. The test results show that the NASA-TLX rating scale score, alpha band absolute power and task false operation rate under the condition of high-intelligent task are lower than those under the condition of low-intelligent task, and the saccade average peak speed under the condition of high-intelligent task is higher than that under the condition of low-intelligent task; in the audio-visual dual modalities task, higher NASA-TLX rating scale score, theta band absolute power and average pupil diameter are observed compared with the single visual modality task. The occupant mental workload under the condition of high-intelligent design is significantly lower than that under the condition of low-intelligent design, and the automation operation and intelligent human-computer interaction mode can effectively reduce the occupant workload of occupant under the high demand for information. The occupant mental workload under the condition of audio-visual dual modalities task is significantly increased compared with the single visual modality task, while the use of dual audio-visual modalities information processing mode is conducive to ensure a better performance under multi-task demands. In addition, the different physiological measurement indices have distinguished sensitivity and diagnostic ability to the influencing factors of mental workload. |
