Abstract |
As measurement methods for fatigue due to video display terminal (VDT) use, eye accommodation time, CFF (critical flicker fusion frequency) and subjective ratings are frequently used. However, these methods have limitations. This research focuses on general fatigue, rather than visual fatigue. A measurement method for general fatigue in visual cognitive work with VDT's is proposed. The proposed method is to measure the decrease of the channel capacity of the central nervous system. The method was applied to various tasks and work environments in 3 experiments. It was able to detect differing degrees of fatigue among various work environments. It seems to be appropriate as a measurement method for general fatigue in actual VDT work. |
