Several aspects of a new, small and inexpensive fatigue assessment tool, the Portable Fatigue Meter (PFM), were studied. In the first experiment the effects of room illumination and distance between the PFM and the eyes on critical flicker fusion frequency (CFF) values were examined. The results revealed that the PFM CFF value varied significantly as a function of the distance between the indicator and the eyes, but it was not affected by room illumination. The effect of ageing on the PFM CFF value was assessed in a second experiment. The results suggested that PFM CFF values are significantly smaller in middle-aged females than in younger females.
对一种新型、小型且价格低廉的疲劳评估工具——便携式疲劳计（PFM）的几个方面进行了研究。在第一个实验中，研究了室内照明以及PFM与眼睛之间的距离对临界闪烁融合频率（CFF）值的影响。结果显示，PFM的CFF值随指示器与眼睛之间的距离变化而显著变化，但不受室内照明的影响。在第二个实验中评估了衰老对PFM CFF值的影响。结果表明，中年女性的PFM CFF值明显低于年轻女性。
