Cinerama sickness and postural instability.
UNLABELLED Motion sickness symptoms and increased postural instability induced by motion pictures have been reported in a laboratory, but not in a real cinema. We, therefore, carried out an observational study recording sickness severity and postural instability in 19 subjects before, immediately and 45 min after watching a 1 h 3D aviation documentary in a cinema. Sickness was significantly lar...
متن کاملPostural instability precedes motion sickness.
We evaluated the hypothesis that postural instability precedes the onset of motion sickness. Subjects standing in a "moving room" were exposed to nearly global oscillating optical flow. In the experimental condition, the optical oscillations were a complex sum-of-sines between 0.1 and 0.3 Hz, with an excursion of 1.8 cm. This optical motion was of such low frequency and magnitude that it was so...
متن کاملPostural Instability and Motion Sickness in a Virtual Moving Room
OBJECTIVE We examined motion sickness in an oscillating virtual environment presented via a video projector system. BACKGROUND Visible oscillation of the physical environment is known to induce both postural instability and motion sickness, but it cannot be assumed that the same phenomena will occur in a virtual simulation of such motion. METHOD Standing participants (3 men and 9 women, 20-...
متن کاملVisually Induced Motion Sickness Predicted by Postural Instability
We investigated whether postural instability can predict motion sickness and studied relations among instability, motion sickness, and vection. Nine men and 4 women (mean age = 19.85 years) were exposed, while standing, to an optical simulation of body sway. Head motion was recorded using a magnetic tracking system. Postural instabilities were observed prior to the onset of motion sickness. Vec...
متن کاملAnticipatory postural adjustments in conditions of postural instability.
OBJECTIVES The purpose of this study was to investigate anticipatory postural adjustments (APAs) in standing subjects who performed a standard motor action triggering a standard postural perturbation (releasing a 2.2 kg load from extended arms) in conditions of different stability requirements. METHODS The degree of stability was varied either by balancing on special boards with long and narr...
