Prediction of seasickness with more than one degree of freedom
conference paper
Human performance at sea generally decreases with increasing severity of seasickness. Seasickness predictions are therefore a valuable tool for both design and operational purposes. Elaborating a previous contribution to this conference, we now present motion sickness predictions induced by combined sway and roll motions.
The model used is based on physiological knowledge of the vestibular (equilibrium) system. This model is based on the facts that I) people without a functioning inner ear do not get sick from motion, 2) motion sickness only arises when gravity changes with respect to a subject's head, and 3) expectation and experience play a key role. This theoretical concept allows any input, translational and rotational, to the vestibular system of passengers. Because a mere description of sickness incidence in response to all different (spatio-temporal) kinds of motion is hardly attainable, this fundamental approach has great advantages.

Het TNO-bewegingsziekte model wordt in dit paper gebruikt om het percentage zeeziekte te voorspellen als reactie op gecombineerde rol- en verzetbewegingen
