Abstract
Motion sickness habituation describes adaptation to stimuli which produce motion sickness. Habituation is important, as it is a natural process which reduces the adverse effects of motion sickness symptoms. Since naval personnel experience relatively long exposures to provocative motions, it is necessary to quantify habituation as a preliminary step towards the goal of quantifying human performance at sea. Scientific and medical literature clearly substantiate the existence of habituation and describe its general behaviour, but a method for defining habituation to ship motions is not available. A brief review of motion sickness and habituation is presented and habituation data from experiments and sea trials are described. The significance of using motion sickness incidence (MSI) as an indicator of the severity of motion sickness is examined. An existing statistical method for predicting the initial exposure MSI is combined with an empirical fit to data for MSI habituation in ship motions. The potential applications and limitations for the MSI habituation model are discussed, and requirements for future research for modeling more complex and changing motions are briefly described.
