At movies theaters and with the new very large home television screens, multiple people simultaneously watch video images together. In this study, we further developed our system that measures two persons' gaze movements simultaneously as they watch video images, in order to evaluate the degree of agreement in their interest and their empathy while viewing the images. We measured the gaze movements among pairs of six adult subjects while they viewed three genres of TV programs, and we analyzed the subjects' head movements as well as gazing points.
