Virtual
reality (VR) offers today a new paradigm for human-computer interaction,
in which users are no longer simply external observers of images
on a computer screen, but active participants within a computer-generated
three-dimensional world. Most of the psychological therapies carried
out with the help of virtual reality rely on the principle of
exposure. This review surveys the state of the art in the field
of virtual reality therapy (VRT). After we have presented what
is VR and some pilot studies, stakes and limits of the utilization
of VR in psychotherapy will be discussed.
