Simulator Sickness Questionnaire: An enhanced method for quantifying simulator sickness.

Abstract: Simulator sickness (SS) in high-fidelity visual simulators is a byproduct of modem simulation technology. Although it involves symptoms similar to those of motion-induced sickness (MS), SS tends to be less severe, to be of lower incidence, and to originate from elements of visual display and visuo-vestibular interaction atypical of conditions that induce MS. Most studies of SS to date index severity with some variant of the Pensacola Motion Sickness Questionnaire (MSQ). The MSQ has several deficiencies as an instrument for measuring SS. Some symptoms included in the scoring of MS are irrelevant for SS, and several are misleading. Also, the configural approach of the MSQ is not readily adaptable to computer administration and scoring. This article describes the development of a Simulator Sickness Questiomaire (SSQ), derived from the MSQ using a series of factor analyses, and illustrates its use in monitoring simulator performance with data from a computerized SSQ survey of 3,691 simulator hops. The databas...

An ecological Theory of Motion Sickness and Postural Instability

Abstract: In this article we present a new theory of motion sickness. In the sensory conflict theory, changes in stimulation of perceptual systems are believed to be responsible for motion sickness. We discuss the fact that these changes in stimulation are not independent of the animal-environment interaction, but are determined by corresponding changes in the constraints operating on the control of action. Thus, provocative situations may be characterized by novel demands on the control of action as well as by novel patterns of stimulation. Our hypothesis is that animals become sick in situations in which they do not possess (or have not yet learned) strategies that are effective for the maintenance of postural stability. We identify a broad range of situations over which the occurrence of motion sickness is related to factors that should influence postural stability. This allows us to establish a logical link between motion sickness and postural stability. Our analysis implies that an understanding of stability s...

Simulator Sickness in Virtual Environments.

Abstract: : Virtual Reality (also known as Virtual Environment or VE) technology shows many promising applications in areas of training, medicine, architecture, astronomy, data handling, teleoperation, and entertainment. A potential threat to using this - technology is the mild to severe discomfort that some users experience during or after a VE session. Similar effects have been observed with flight and driving simulators. The simulator sickness literature forms a solid background for the study of sickness in virtual environments and many of the findings may be directly applicable. This report reviews literature concerning simulator sickness, motion sickness, and virtual environments. Forty factors that may be associated with simulator sickness in virtual environments are identified. These factors form three global categories: subject, simulator, and task. The known and predicted effects of these factors on sickness in VEs are discussed. A table summarizes the information presented in this report. The information can be used as a guide for future research concerning simulator sickness in virtual environments.
