A basic study of a face-to-face image presentation system

Recently, broadband networks have made great progress and various interactive visual communication systems including video conferencing, video telephones and video networks for meetings are becoming increasingly popular. However, unnatural eye contact in the displays used by these communication systems has presented a barrier to natural conversation between communicators. We confirmed the possibility of realizing the feeling of eye contact that is part of natural face-to-face conversation. This paper also describes experimental results on the permissible eye-line angle that gives a sense of eye contact and the influence of image resolution.
