To assess mental fatigue by noninvasive monitoring of the physiological signals.
The changes in the physiological parameters including the electrodermal activity, heart rate and heart rate variability were analyzed in 14 subjects performing the reaction-time tasks when fatigue and changes in the reaction time occurred.
The average skin conductance level, average heart rate, and heart rate variability parameters including the total power density, percentage of the very low power density, percentage of high power density all differed significantly between the sober state and the mental fatigue state.
Monitoring the physiological parameters including the electrodermal activity, heart rate and heart rate variability is a noninvasive, effective and practical approach to mental fatigue assessment.
通过对生理信号的无创监测来评估精神疲劳。
对14名执行反应时间任务的受试者在出现疲劳及反应时间变化时的生理参数变化进行分析，这些生理参数包括皮肤电活动、心率和心率变异性。
清醒状态和精神疲劳状态下的平均皮肤电导水平、平均心率以及心率变异性参数（包括总功率密度、极低功率密度百分比、高功率密度百分比）均存在显著差异。
监测包括皮肤电活动、心率和心率变异性在内的生理参数是一种无创、有效且实用的精神疲劳评估方法。
