Our
usability test battery measures physiological parameters derived from
the human autonomous nervous system to provide information on the
users’ level of comfort, strain, stress, relaxation, anxiety,
etc. - by and large without the possibility on the user side to
influence these parameters voluntarily. By adding neurophysiologic
parameters to such a set of measurements (for example EEG), even
concepts such as mental work load, cognition, etc. can be adressed. |

To
treat the fear of flying, heights, tight spaces, etc. VR exposure
therapy is a safe and successful procedure. Its popularity is justified
by its lower costs than in vivo exposure, its ability to have total
control of the environment, the repeatability of any phobic stimuli and
its safety. In controlled stages patients will be exposed to virtual
environments using stereoscopic displays as HMDs or projection based
systems, where the virtual environment elicits progressively higher
levels of anxiety. Each stage can be repeated until the patients
anxiety has lessened and they feel ready to move to a higher level. |
