TITLE : Interdisciplinary Studies on the Combat Readiness and Health Issues Faced

چکیده

The goal of this study was to detect the level of arousal induced by pictures of negative, positive and neutral affective valence by measuring the pupil dilation of 4 subjects. In order to detect arousal from pupil dilation data, it was necessary to reduce the effect of luminance. This required comparing the picture luminance measures to the collected pupil dilation data, and applying additional processing to reduce the effect of luminance. The applied algorithm extracted the component of pupil dilation orthogonal to picture luminance measures. Although this processing increased the arousal “score” of some high arousal (as opposed to neutral) pictures, neutral pictures still had higher scores than expected. This suggests a nonlinear relationship between pupil dilation and luminance.
