Abstract:
Many forms of transport evoke symptoms of motion sickness (MS) in susceptible passengers. Symptoms include stomach awareness, palor, headache, sweating dizziness and nausea, and are caused by
particular vehicle motions. The aim of this review is to summarize the literature on the relationship between motion characteristics and motion sickness. For example, which types of motions are most provocative, what is the effect of motion frequency and amplitude, and how can we predict whether a certain motion will be provocative.
This review was carried out within the framework of the CORINNE project, which investigates the relationship between vibration characteristics in helicopters and the discomfort they cause on the
passengers. The ISO 2631-11 proposes a method of predicting motion sickness incidence from a given motion profile, but only takes into account the vertical motion. It is to be expected that the prediction
will not be optimal for helicopter trajectories, as motions in other degrees of freedom may also contribute. One of the project aims, therefore is to verify whether the current ISO method is valid, or whether it can be improved by taking motion in multiple degrees of freedom into account.
In the following, we will first summarize the prediction method proposed in ISO 2631-1 and then summarize available literature on the effects of motions in other degrees of freedom. This review can then guide further research for the specific case of helicopter flight.
