Simulator sickness is a common occurrence when humans navigate virtual environments; some proportion of the population will experience nausea, disorientation, headache, and a number of other negative symptoms during and after an interaction with a flight simulator, driving simulators, or first-person video game. While there are a number of theories behind the causes of simulator sickness, including theories related to posture stability and body movement, there are still no accepted explanations for why some people are more susceptible to sickness compared to others. Some theories suggest that eye and head movements, age, gender, and simulator scenario properties (e.g., number of turns) may have an effect on simulator sickness. We took advantage of already collected eye movement, simulator sickness, and demographic data and explored possible correlations between simulator sickness and a variety of factors, such as the ones that were mentioned above. Of particular interest was whether eye tracking data might predict sickness severity. Results indicated that gender was significantly related to simulator sickness (females reporting greater sickness), and there was a trend for a relationship between age and simulator sickness, with increased age being specifically related to general discomfort and symptoms of vertigo. Contrary to predictions, eye scanning parameters were not significantly related to simulated sickness. Study limitations and future directions are discussed.
