A Basic Study toward VE-Sickness Assessment

Abstract

Recently, "Virtual Environments"(VE) technology also called as "Virtual Reality" has rapidly advanced. However, a potential hazard to users of VE has been discussed. Actually, it is reported that some users complain of discomfort during and after the experience of VE. We have started the study toward VE-Sickness assessment. This paper reports the results of our preliminary experiment focusing on the autonomic responses such as heart rate, respiration, electrogastrogram, and so on. Twenty subjects participated in the experiment and were given some types of simulated viewpoint movement in a random dots environment. The results show the correlation between the subjective feelings of discomfort in VE-sickness or other stress such as "irritation" and the respiratory frequency.
