Evaluation of Symptoms and Effects of Virtual Reality Based Flight Simulation and Enhanced Sensitivity of Postural Stability Measueres

In order to investigate level of experienced sickness symptoms in a VR based air combat simulator, a combined methodology was used. Before, during, and after simulation the participants repeatedly answered a VR sickness symptoms questionnaire (VRSQ). In addition, before and after simulation their postural stability was measured. In order to investigate if measurements of postural stability can be made more sensitive to changes in postural stability, during the measurements a sideways rolling wide angular visual flow was presented to half of the participants. Only low levels of VR-sickness symptoms and effects on postural stability were found. However, headache caused by the Head Mounted Display was a major concern for most participants. The presentation of a visual flow during the measurements of postural stability led to generally higher levels of postural instability, but did not increase the sensitivity of the measurements.
