Abstract

Although modern society has improved the value of intellectual work, its objective and quantitative evaluation method has not been established. In this study, the authors have focused on physiological indices such as pupil diameter and heart rate variability which are supposed to be influenced by their cognitive load in office work, and an estimation method of intellectual concentration states from the measured indices has been proposed. The concentration states to be estimated in this study are one of three states when giving three kinds of cognitive loads which are high, medium and low. As the result of the experiment where intellectual concentration states of 31 participants were estimated, the accuracy was 57.3% in average and it was significantly higher than random estimation (p < 0.001). It was also found that those who had no clear physiological response caused by the difference of cognitive load or those who showed different physiological response when measuring in different time tended to be low estimation accuracy.
