Publisher SummaryThis chapter presents the study of three kinds of monotonous video display terminal (VDT) work that have different interface. During repeated monotonous work, which needs less physical exercise, most of workers shift to low awakening condition. Then the characteristic of shifting time to this condition are recorded. Experiment 3 this work is an analogous behavior which is more continual and tends to shift to low awakening level. Experiment 1 this work is a digital behavior, it's rhythmical and need a little judgment. However, they get used to this work then shift to low awakening level. In experiment 2 they need ability of calculate which is a high-level brain activity. They feel not only monotonous but also fatigue and shift to low awakening level. In term of the appearance time of grouped a waves there are few difference among three types of interaction. During monotonous work which receives less stimulation from outside and needs less physical exercise we confirm that electroencephalography that reflect physical condition directly change from 20 to 30 minutes later and awakening level go down objectly. They cannot prevent drowsiness. There are two reasons why we shift to low awakening level. They are monotonousness and fatigue.
