Psychophysiological Measurements Applied to Maintainability Evaluation of Equipment Design.
Abstract
The paper presents a proposal for using psychophysiological measurements to aid in evaluating equipment designs from the human factors engineering viewpoint. As a preliminary step in examining the feasibility of applying this method, an experiment was conducted to determine if man's reaction to task difficulty as affected by equipment design features is reflected in psychophysiological indices. Subjects were presented with two similar maintenance type tasks to be performed on differently designed pieces of equipment. One task involved equipment which obviously facilitated ease of maintenance. The other task involved equipment which has difficult to maintain. Various psychophysiological measurements were taken of the subjects as these presentations were made. It was found that a majority of the measured indices were higher during the hard task than during the easy task. However, these differences were not significant at the significance level selected for use in the statistical analysis. (Author)
