Abstract:
Moviemakers must be able to estimate moviegoer’s level of engagement while watching the movie. Thus far, however, most studies have focused on the story itself from the viewpoints of subjective reviewers. In this study, we tried to estimate the engagement of moviegoers objectively by measuring their physiological signals. The physiological signals include electroencephalogram and photoplethysmogram. However, it is difficult to measure biomedical signals compared to subjective review questions. Therefore, many researchers want to share the biomedical signal data. For this reason, it is important to evaluate the reliability of the biomedical signal data. In this research, we invented a new formula for engagement and evaluated the reliability of the biomedical signals measured from moviegoers as participants. The reliability of our data is verified by its consistency between electroencephalogram and photoplethysmogram as well as by comparison to subjective review results.
