Interactive 3D environments are valuable tools for the assessment and adjustment of human behavior. Driving a virtual car is cheaper, safer and more sustainable than driving on road. However there is one major problem related to the use of 3D environments for assessment and training. A significant part of simulator operators suffer from symptoms resembling motion sickness, or more specifically simulator sickness. A common indicator for experienced operators is 30%, however this varies greatly. Symptoms can persist for long periods of time. Some drivers are not able to drive their vehicle after a simulator session. This discomfort has a negative influence on the acceptance of 3D environments for assessment and adjustment of human behavior. Research by Johnson, Kingdon et al. and Stanney et al. indicates that in 1 to 1.5% of the operators that are exposed to a simulated environment, vomiting is induced To prevent unnecessary delay of 3D environment development as a tool for the assessment and adjustment of human behavior, users and producers of interactive 3D environments will have to find effective methodology to reduce the severity of symptoms caused by simulator sickness. In addition new methods are needed to decrease the intensity of simulator sickness. (Author/publisher)
