Abstract:
The recent development of advanced digital humans has the potential to faithfully represent human nonverbal information. There are many examples of the use of digital humans for interactive communication, such as customer support and digital healthcare. There are, however, issues to be addressed as communication tools because of the lack of evidence regarding the extent to which nonverbal communication is performed by digital humans. In this study, we evaluate the quality of facial expressions by the digital human and its actors objectively using deep learning-based facial expression recognition. For the experiment, facial images of an actor expressing six basic emotions (anger, fear, disgust, happiness, surprise, and sadness) and a digital human face resembling the actor were captured, and scores of both facial expressions were measured. The results showed that the expression of "happiness" by the digital human and its actor were significantly consistent, but there were no significant differences in other facial expressions. The facial expression recognition used in this experiment was not trained on digital humans, thus there were cases in which the facial expressions of digital humans could not be judged accurately.
