This paper presents an experiment designed to investigate the impact of scommunication in an immersive virtual environment.Participants were paired by gender and were randomly assigned to a CAVE-like system or a head-mounted display. Both were represented by a humanoid avatar in the shared 3D environment. The visual appearance of the avatars was either basic and genderless (like a "match-stick" figure), or more photorealistic and gender-specific. Similarly, eye gaze behavior was either random or inferred from voice, to reflect different levels of behavioral realism.Our comparative analysis of 48 post-experiment questionnaires confirms earlier findings from non-immersive studies using semi-photorealistic avatars, where inferred gaze significantly outperformed random gaze. However responses to the lower-realism avatar are adversely affected by inferred gaze, revealing a significant interaction effect between appearance and behavior. We discuss the importance of aligning visual and behavioral realism for increased avatar effectiveness.
