Evaluation of Performance Using Electrooculogram: Performance in a Working Task Involving Periodic Eye Movements

The purpose of this study was to evaluate the performance based on psychophysiological states in a working task involving periodic eye movements using electrooculogram (EOG). EOG during the task were compared to electrocardiogram (ECG) and task scores during the task and subjective scores after the task. As the results, there were relationships in which the autocorrelation coefficients of time-series behaviors of EOG became larger as the task scores and the impressions of the task results became better. Furthermore, there were relationships in which the task scores and the autocorrelation coefficients of time-series behaviors of EOG became larger as RR interval and coefficients of variation of RR interval (CVRR) by ECG became smaller. Time-series behaviors of EOG became stable and sympathetic nervous activity increased according to the increase of the task scores. Thus, it was demonstrated that performance based on psychophysiological states in a working task involving periodic eye movements can be evaluated by time-series behaviors of EOG.
