Social Presence: The Role of Interpersonal Distances in Affective Computer-Mediated Communication Pfeiffer, Thies Pfeiffer Thies Wachsmuth, Ipke Wachsmuth Ipke Emotions and interpersonal distances are identified as key aspects in social interaction. A novel Affective Computer-Mediated Communication (ACMC) framework has been developed making the interplay of both aspects explicit to facilitate social presence. In this ACMC framework, the displays can be arranged in virtual space manually or automatically. We expect that, according to empirical findings, the social relation as well as momentarily affective appraisals will influence this arrangement. The proposed concept extends from desktop devices to fully immersive Virtual Reality interfaces. 275-279 275-279 CLEUP Cooperativa Libraria Universitaria Padova 2008
