  This paper proposes a perceptual visual analysis regarding the personality of
virtual humans. Many studies have presented findings regarding the way human
beings perceive virtual humans with respect to their faces, body animation,
motion in the virtual environment and etc. We are interested in investigating
the way people perceive visual manifestations of virtual humans' personality
traits when they are interactive and organized in groups. Many applications in
games and movies can benefit from the findings regarding the perceptual
analysis with the main goal to provide more realistic characters and improve
the users' experience. We provide experiments with subjects and obtained
results indicate that, although is very subtle, people perceive more the
extraversion (the personality trait that we measured), into the crowds of
virtual humans, when interacting with virtual humans behaviors, than when just
observing as a spectator camera.
