Berbaum, Kevin S., Kennedy, Robert S. and Braun, Curt C. (1994): Postural Disequilibrium Following Adaptation to Virtual Environments: Concern for Post Simulator Activity. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. p. 986.

“Virtual environment technology may increase the usefulness of simulation in military training by improving on some aspects of current technology and by permitting simulation to be applied in training domains not currently addressed. However, like its forerunner -- current simulation technology, there may be some hazards associated with its use. To assess changes in postural stability associated with adaptation to simulated environments, measures of simulator sickness and postural stability were taken from 127 military pilots completing flight training in a helicopter simulator which included full 6 degrees of motion and 60 inches of travel. Before and after each of ten simulator flights flown every weekday for two weeks, the participants completed a Simulator Sickness Questionnaire, a self report symptom checklist that may be scored for nausea, visuomotor and disorientation. In addition, before-and-after tests of walking and standing steadiness were completed. Postflight sickness was significantly greater than preflight. Postflight postural stability was significantly lower than preflight stability. Both motion-sickness and postural stability decreased across ten exposures to the simulator. That individuals adapt to the simulator is indicated the reduction in reported motion-sickness following repeated exposure. However, as they become increasing adapted to the simulated environment, they experience a reduction in postural stability upon leaving the simulator. As they become adapted to the simulator, they are less well adapted to the real world. The implications of an individual who is less able to function in the real world extend far beyond the training effectiveness of a simulator or the symptoms experienced by a trainee. Individual adapted to a virtual environment should not be expected to interact appropriately with the now non-adapted real world.”

Kennedy, Robert S., Berbaum, Kevin S. and Smith, Martin G. (1993): Methods for Correlating Visual Scene Elements with Simulator Sickness Incidence. In: Proceedings of the Human Factors and Ergonomics Society 37th Annual Meeting 1993. pp. 1252-1256.

“Simulator sickness occurs in a large number of Army, Navy, and Marine Corps simulators, and is most prevalent in moving-base, rotary-wing devices which employ cathode ray tube (CRT) video displays as opposed to fixed-wing, dome-display trainers with no motion base. Based on data from a factor analysis of over 1000 Navy and Marine Corps pilot simulation exposures, a new scoring procedure was applied to two helicopter simulators with similar rates of simulator sickness incidence. Based on the factor analytic scoring key, the two simulators showed slightly different sickness profiles. Preliminary work was begun to record the visual scene by video frame-by-frame decomposition and automated scoring algorithms were developed. The findings are discussed from the standpoints of (1) recommendations for future design and use of simulators, and (2) the metric advantages and other merits of the "field experiment" methodology to address human factors problems with simulator sickness.”

Hettinger, Lawrence J., Nolan, Margaret D., Kennedy, Robert S., Berbaum, Kevin S., Schnitzius, Kevin P. and Edinger, Katrina M. (1987): Visual Display Factors Contributing to Simulator Sickness. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 497-501.

“The history of research on visually-induced illusory self motion, or vection, has demonstrated that in many instances observers have experienced disturbances similar to those of motion sickness. Visual displays in flight simulators may also produce the experience of vection, and illusions of self motion are likely to become more common with the increased use of wide field-of-view presentations of realistic imagery. Many of the disturbances observed in laboratory studies of vection have also been found in simulators, and are likely to become more common. This paper presents a background to the study of visual-vestibular disturbances associated with illusory self motion in flight simulators, and an overview of current experimental efforts aimed at identifying the causal factors.”
