It was only several decades ago that physiological measurements were recognized as effective indicators of human physical and mental conditions in occupational health or ergonomics. The recent rapid progress in sensor and signal processing techniques, however, made these available for practical evaluation techniques. This paper is an overview of the accumulated techniques in several fields including experimental psychology, physiology, medical sciences, and ergonomics. The major topics described herein are as follows: 1) properties and merits of physiological measurements compared with the other techniques, 2) applicability of various physiological indicators evaluated from noninvasive, ambulatory and continuous monitoring techniques, 3) practical physiological measurements and signal processing systems which can be applied at actual workplaces and environment, 4) effective and useful evaluation techniques of physiological indicators such as ECG, blood pressure, respiratory parameters, EEG, EBP, EMG body movements, body temperature, perspiration, eye movements, CFF and electrodermal activities. Our review of 235 published papers has shown that physiological measurements have made a significant contribution to the assessment of physical and mental workload, CNS (central nervous system) activity level and work performance. However, further studies should be made on detail mechanisms and individual variations.
