Motion sickness preceded by unstable displacements of the center of pressure

Adaptation to simulator sickness in older drivers following multiple sessions in a driving simulator

“…Previously, Stoffregen et al 20 have demonstrated that postural instability, measured as head and torso displacements when standing, preceded the appearance of motion sickness symptoms and increased with prolonged exposure to nauseogenic stimuli 35 . In the present paper, compared with the LS group, mean head range of motion and variability of the participants who expressed mild simulator symptoms showed only a weak trend toward increased instability.…”

Postural Instability and Motion Sickness in a Virtual Moving Room

“…Postural instability has preceded motion sickness in studies using widely differing types of visual motion, including linear oscillations along the line of sight (e.g., Bonnet, Faugloire, Riley, Bardy, & Stoffregen, 2006;Stoffregen & Smart, 1998), angular oscillations around the line of sight (Stoffregen et al, 2000), and multiaxis motions that occur in console video games (Stoffregen et al, 2008 [this issue]). This effect confirms a prediction of the postural instability theory of motion sickness (Riccio & Stoffregen, 1991).…”

“…DFA describes the relation between the magnitude of fluctuations in postural motion and the time scale over which those fluctuations are measured (Chen, Ivanov, Hu, & Stanley, 2002). DFA has been used in several studies of unperturbed stance (e.g., Riley, Balasubramaniam, & Turvey, 1999), as well as in previous work relating postural activity to visually induced motion sickness (e.g., Bonnet et al, 2006). We conducted inferential tests on α, the scaling exponent of DFA.…”

Technical factors influencing simulator sickness

“…Although in this study more than 1000 pilots and 10 different simulators (with moving and fixed base platform) were engaged, the study did not confirm that the use of the moving platform prevents the simulator sickness [8,31]. There are opinions, that the use of moving platform does not prevent the simulator sickness [8].…”
