Resumen
The aftereffects from exposures to virtual environments (VE) have often been evaluated using the Simulator Sickness Questionnaire (SSQ), which was originally devised to evaluate computer-based simulator systems. The SSQ consists of a checklist of 26 symptoms, each of which is related in terms of degree of overall severity, with the highest possible total score being 300. The SSQ also provides scores on three subscales representing separable but somewhat correlated dimensions of simulator sickness. Results from SSQ highlight an interesting difference between VE exposures and other disorienting environments. The immediate post-exposure profiles usually indicate that VEs tend to produce more disorientation (D) than neuronegative (N) symptoms, such as nausea, and fewer oculomotor-related (O) disturbances, such as eyestrain. It is important to note that this D>N>O profile does not match the profiles of other provoactive environments, including space sickness, which has an O>D>N profile, simulator sickness, which has and O>N>D profile, or seasickness and airsickness which have N>D>O profiles.
