Study of Interviewee's ImpressionMade by Interviewer Wearing Digital Full-face Mask DisplayDuring Recruitment Interview.

During recruitment interviews, the facial impressions of the interviewers likely affect the nervousness of the interviewees and make it difficult to conduct fair and consistent interview processes. To minimize the difference in facial impressions among interviewers, we have investigated a method to convert an interviewer’s face into an avatar. In this study, we used a digital full-face mask display capable of replacing the wearer’s face with an avatar in the real world. By reproducing the interviewer’s facial expression with an avatar in real time, we investigated the effect of avatar appearance on interviewee’s nervousness during interviews. Two types of avatars (a dignified face and a gentle face) were applied to three male interviewers in different age groups (10s, 20s and 60s). We compared the level of interviewee’s nervousness between before and after augmenting interviewer’s face with avatar. 172 college students were recruited as interviewees to assess the variation in the level of nervousness. Our experimental results show that avatar appearance can elicit more unique and consistent impressions than the interviewer’s real face and reduce the variation in interviewee’s nervousness level across interviewers.
