Novel application of 3D range image sensor for estimation of interests based on fixation time of face orientation

摘要

In this paper, we describe the relationship between the presence or absence of interest and the fixation time of face orientation. There is a conventional method of measuring the fixation time of line-of-sight orientation to prevent accidents due to carelessness. In addition, studies are being performed on the estimation of the relationship between face orientation and line-of-sight orientation. However, even if face and line-of-sight remain, it has not been confirmed whether people are interested. Therefore, we conducted experiments to investigate the relationship between the presence or absence of interest and the fixation time of face orientation. We simultaneously measured the change in interest and face orientation with time as subjects watched two movies. As a result, it was suggested that face orientation remained longer for an object of interest.
