Viewer Arousal Display System Using Eye-Tracking and Skin Conductance Data

Abstract

We developed a viewer arousal display system that can represent the viewers' physiological responses about emotional arousal in fixation areas on frames of a viewed video by measuring and recording viewers' physiological signals and eye movements. We implemented two prototypes of the system. One of the prototypes superimposes the information in position, hue, and saturation of heat maps on the video. The second prototype represents the information with position, height, and color of bar graphs around the video. The system can solve a problem in previous systems, which were unable to display an important area in a frame of a video and can be useful for video creators or analyzers to estimate and analyze viewers' responses to a video. Additionally, we conducted an experiment to verify the effectiveness of the system. The results demonstrate that the fixation areas that the system calculated from the eye-tracking generally overlapped with the subjective reported attention points. However, the subjective arousal values varied slightly from the estimated arousal values from the SC data.
