According
to Wikipedia, an avatar (usually translated from Sanskrit as incarnation) is
the graphical representation of the user or the user’s alter ego or character.
It may take a three-dimensional form as in games or virtual worlds ... Studies at the University of Michigan showed that when people create and
modify their virtual reality avatars, the hardships faced by their alter egos
can influence how they perceive virtual environments. For example, Sangseok
You, a doctoral student in the school of information at the University of
Michigan, reported that participants who saw that a backpack was attached to an avatar
that they had created
overestimated the heights of virtual hills, just as people in real life tend to
overestimate heights and distances while carrying extra weight. “You exert more of
your agency through an avatar when you design it
yourself," said S. Shyam Sundar, Distinguished Professor of Communications
and co-director of the Media Effects Research Laboratory, Penn State, who
worked with You. "Your identity mixes in with the identity of that avatar
and, as a result, your visual perception of the virtual environment is colored
by the physical resources of your avatar." The study may help trainers and
game developers design virtual reality exercises and games that are more
realistic and more immersive¾because "You are
your avatar when it is customized."
