We investigated whether a digital human applicant generated by a combination of posture prompts and additional text prompts elicited a good or bad first impression during an interview in a virtual space. Existing analytical studies have not evaluated whether a combination of posture prompts and additional text prompts can improve an interviewer’s first impression of a digital human applicant in an interview setting. To examine this issue, we generated images of digital human applicants by combining the presence or absence of posture prompts and the presence or absence of additional text prompts. We conducted subjective assessments in which participants simulating interviewers in a virtual space reported their first impressions of the images. The experimental results demonstrated that interviewers’ first impressions of a digital human applicant generated by combining posture prompts and additional text prompts were better than their first impressions of a digital human applicant generated without prompts.
