Motion sickness has been a problem for travelers and military personnel for quite some time. Improvements in vehicle technology and design have resulted in the reduction of motion sickness in the physical (vehicular) environment. However, with the development of virtual technologies, sickness has become increasingly common in non-vehicular situations. Unlike vehicular sickness, motion sickness produced by virtual environments (VE) is not alleviated by general improvements in VE technology. A theory of motion sickness developed by Riccio and Stoffregen (1991) asserts that sickness in real and virtual situations can be attributed to disruptions in postural control (stability). An initial test of the postural instability theory demonstrated that reports of motion sickness are preceded by gross disruptions in postural control (Stoffregen & Smart, 1998). In the current investigation, I studied relations between visually induced motion sickness and postural motion in two different venues. The goal of the research was to determine whether the indices used in Stoffregen and Smart (1998) were reliable and generalizable across different venues. A total of 27 participants were exposed to low frequency, sinusoidal motion. Half of the participants were exposed via a high fidelity virtual environment, the other half utilizing a moving room. Postural motion was measured using a magnetic tracking system (Flock of Birds, Ascension, Inc.), that recorded motion of the head. Pre-exposure and post-exposure symptomology data were collected using the Simulator Sickness Questionnaire (SSQ: Kennedy, et. al., 1993). Based on participants' subjective reports (i.e., whether they indicated that they were motion sick), the participants were separated into sick and well groups. A discriminant function analysis was performed in order to determine what factors functioned to classify participants into sick and well groups. Despite the differences in motion (translation/rotation), and differences in posture (seated/standing) it was predicted that the factors that produced sickness in each of these conditions would similar in nature. Postural measures were found to be successful in predicting motion sickness in each experiment. Specifically, it was found that the variability of vertical motion and the velocity of pitch motion predicted who would later become motion sick in both venues. This generalizability suggests that vehicular, space, and simulator (VIMS) sicknesses may not be independent maladies as previously thought.
