Abstract

Physical proximity and appearance guide people to interact with each other in different ways [1,6]. However, in Video-Mediated Communications (VMC), these are distorted in various ways. Monitors and camera zooms make people look close or far, monitors and camera angles can be high or low making people look tall or short, volume can be loud or soft, making people sound assertive or submissive, --all independent of the true physical characteristics or intentions of the participants. Here we test the apparent height of a person on how dominant they are in a group decision-making task. We found that the artificially tall people had more influence in the group decision than the artifically short people.
