项目摘要

Purpose of this study is to develop the methods to apply the EOG (electro-oculogram) measures for psychophysiology of sleepiness and fatigue concerning safety and comfort in industrial workers. Measurements of EOG are relatively easily applicable for human performing various tasks. Components of EOG including eye-blinking, saccades, slow eye movements (SEM) may provide various information about fatigue and other psychophysiological states of human.In the research 1 of this project, experimental examination was performed to clarify the usage of EOGs as a measure for sleepiness. EOG, overt behavior and subjective reports were recorded in relatively static and monotonous situation of "hearing a lecture". In the results of correlation analyses, the SEM was useful to detect the strong level of sleepiness or "dozen-off'. Eye-blink- durations showed positive correlation to the level of subjective sleepiness.In the next research (research 2), EOG indices were applied to long-haul overnight tru … More ck driving. EOG, EEG (electroencephalogram), ECG (electrocardiogram), video-images (forward view and behavior of the driver), distance from the car ahead (measured by infrared instruments) were recorded. Increase of eye-blink-duration was observed in the time of midnight to early morning, accompanied by the increase in subjective sleepiness and subsidiary behavior, and followed by spontaneous break or nap in many cases. Traffic condition was the main factor which affects the frequencies in eye-blinking and saccades. However, strong sleepiness was related to a remarkable decrease in the frequencies of eye-blinking and saccades when the traffic condition was monotonous. Results indicate that the combination of observation of duration and frequencies in eye-blinking, horizontal-EOG, and traffic conditions, subsidiary behavior is useful to evaluate the driver's sleepiness.In the research 3, methods and tools developed in these researches were applied to a professional truck-driver in permanent night work. Results showed enhancement of sleepiness during the succession of night work. Less

本研究的目的是开发应用 EOG（眼电图）测量方法来测量与产业工人安全和舒适相关的嗜睡和疲劳心理生理学。 EOG 测量相对容易地适用于人类执行各种任务。眼电图的组成部分包括眨眼、扫视、慢眼动（SEM），可以提供有关人类疲劳和其他心理生理状态的各种信息。在本项目的研究1中，进行了实验检查以阐明眼电图作为睡意测量的用途。在相对静态、单调的“听课”情境中记录眼电图、外显行为和主观报告。在相关分析的结果中，SEM 可用于检测强烈的睡意或“打瞌睡”的程度。眨眼持续时间与主观睡意水平呈正相关。在下一项研究（研究 2）中，EOG 指数应用于长途夜间驾驶。EOG、EEG（脑电图）、ECG（心电图）、视频图像（前视和行为）驾驶员），与前方车辆的距离（通过红外仪器测量）被记录。在午夜至凌晨期间观察到眨眼时间增加，伴随着主观睡意和附属行为的增加，随后在许多情况下会自发休息或打盹。交通状况是影响眨眼和扫视频率的主要因素。然而，强烈的困倦与睡眠频率的显着下降有关。当交通状况单调时，会出现眨眼和眼跳的情况。结果表明，结合眨眼持续时间和频率、水平眼电图和交通状况、辅助行为的观察有助于评估驾驶员的睡意。在研究 3 中，这些研究中开发的方法和工具应用于长期夜间工作的专业卡车司机。结果显示，连续夜间工作期间睡意增强。少
