The acceptance of automated driving is under the potential threat motion sickness. It hinders passengers' willingness to perform secondary activities. In order mitigate sickness in vehicles, we propose an optimization-based planning algorithm that minimizes distribution acceleration energy within frequency range found be most nauseogenic. formulated into integral and receding-horizon variants c...

BACKGROUND The current study investigated the effects that vertical display oscillation had on the development of both vection and simulator sickness. METHODS There were 16 subjects who were exposed to optic flow displays which simulated either: 1) constant velocity forward self-motion (pure radial flow); or 2) combined constant velocity forward and vertically oscillating self-motion (radial ...

In a study of 18 human subjects, we applied a new technique, estimation of the transfer function between instantaneous lung volume (ILV) and instantaneous heart rate (HR), to assess autonomic activity during motion sickness. Two control recordings of ILV and electrocardiogram (ECG) were made prior to the development of motion sickness. During the first, subjects were seated motionless, and duri...

The pathogenesis of motion sickness includes both inner-ear stimulation by body movement, especially a Coriolis-type stimulus, and optokinetic stimulation due to the shift of the surrounding visual fields. According to Kornhuber, Sakata and others, the vestibular cerebellum also participates in an important way. We conducted this study to elucidate the influence of the vestibular cerebellum on ...

A mathematical model of motion sickness incidence (MSI) is derived by integrating neurophysiological knowledge of the vestibular system to predict the severity of motion sickness of humans. Bos et al. proposed the successful mathematical model of motion sickness based on the neurophysiological mechanism based on the subject vertical conflict (SVC) theory. We expand this model to 6-DOF motion, i...

Background: Motion sickness is a common problem experienced by much the population. Clinical treatments at this time are primarily pharmacological. Currently it is known that multiple exposures to motion sickness triggers can, over time, result in habituation and the patient can become free of symptoms. This repeated recurrence of sickness is not desirable or practical to daily living. Limited ...
