The temporal pattern of VR sickness during 7.5-h virtual immersion

Abstract

AbstractIn this study, we assessed the relationship between exposure duration and VR sickness severity during 7.5-h virtual immersion. First, we showed that the VR sickness severity was positively correlated to the exposure duration: the longer participants were exposed to the VR environment, the more severe sickness symptoms they had. Second, we showed a dynamic sickness adaptation process during a long time of VR exposure: the sickness adaption effect that had already been established could be broken as the exposure duration continued to increase, and a new sickness adaption process would establish. Moreover, we showed a distinguishable symptom profile of HMD compared with LCD, which was insusceptible of exposure duration. This is the first report presenting the temporal pattern of VR sickness during such long-duration exposure. Our study could offer a predictive model of VR sickness severity level during long virtual immersion and provide suggestions for the use of VR technology for scientific study, clinical application, and business entertainment.
