Research output: Contribution to journalConference articlepeer-review


The hypothesis that postural instability precedes the onset of motion sickness was evaluated. Subjects were exposed to nearly global oscillating optical flow within a fixed-base flight simulator. The optical oscillations were a complex sum-of-sines between 0.1 and 0.3 Hz, in the roll axis. This produced motion sickness in 43% of subjects.
