“…We hypothesized that the duration and severity of mal de debarquement are correlated with motion sickness severity, insofar as both syndromes might stem from a failure to adapt to new motion conditions. A second hypothesis was that the AH, which was recently found to alleviate motion sickness severity [32], might reduce the occurrence and severity of mal de debarquement. The rationale behind our second hypothesis was that abolition of the conflict between vestibular and visual input by the AH would reduce the motion-induced adaptive processes required to solve this conflict.…”

BACKGROUND: Exposure to unfamiliar motion patterns commonly results in motion sickness and a false perception of motion, termed mal de debarquement, on the return to stable conditions. OBJECTIVE: To investigate whether motion sickness severity is correlated with the duration and severity of mal de debarquement; to study the possible preventive effect of projecting earth-referenced scenes (an artificial horizon) during exposure to motion on the development of mal de debarquement. METHODS: Thirty subjects were exposed to the recorded motion profile of a boat in a 3-degrees-of-freedom ship motion simulator. During the simulated voyage, the study participants were repeatedly put through a performance test battery and completed a motion sickness susceptibility questionnaire, while self-referenced and earth-referenced scenes were projected inside the simulator cabin. Six hours post disembarkation, subjects completed a questionnaire on mal de debarquement duration and severity. RESULTS: Mal de debarquement, mostly of mild severity, was reported following 59% of the exposures to the provocative motion profile, and in 79% of cases lasted less than 6 hours. The incidence of mal de debarquement, its duration, and the severity of symptoms did not differ between the various artificial horizon projection modes. Significant correlations were found between motion sickness severity and the duration and severity of the mal de debarquement that followed. CONCLUSIONS: The significant correlations found between motion sickness severity and mal de debarquement duration and severity imply that both syndromes might stem from a failure to adapt to new motion conditions. There is a disparity between the previously reported reduction in motion sickness symptoms by an artificial horizon, and its failure to influence the duration and symptoms of mal de debarquement. This might be explained by the different response in the two syndromes, physical versus cognitive.

“…Taken together, our results indicate that participants experiencing weak or moderate levels of motion sickness may still able to perform at their best. Results from studies of cognitive performance in relation to motion sickness have varied depending on the type of performance task used and whether motion sickness was visually or motion induced [2,5,8,25]. Speculatively, when motion sickness is induced by a stimulus that includes a motion component, it is plausible that performance could be mainly affected by the motion and not by the evolving motion sickness [1].…”

“…Research on how different cognitive abilities are affected by motion sickness is, however, sparse. Recent studies have reported decreased cognitive task performance [1,2] in motion sickness triggering environments. However, these studies did not specifically address the relationship between perceived motion sickness and cognitive performance.…”

Background: Motion sickness has previously been found to deteriorate performance. In complex working environments, sustained ability to perform despite motion sickness is crucial. This study focuses on effects of motion sickness on encoding and retrieval of words. In addition, the temporal development of psychophysiological responses and their relationship with perceived motion sickness were investigated. Methods:Forty healthy participants (20 male and 20 female, age 19-51) performed an encoding and retrieval task during exposure to an optokinetic drum and were compared with 20 controls (8 male and 12 female, age 21-47) not exposed to motion sickness. Measurements of heart rate, heart rate variability, skin conductance, blood volume pulse, respiration rate, and skin temperature were made throughout optokinetic drum exposure.Results: Moderate levels of motion sickness did not affect the ability to encode or retrieve words. Perceived motion sickness was positively related to heart rate, blood volume pulse and skin temperature and negatively related to respiration rate. Conclusions:The psychophysiological measurements did not show consistent patterns of sympathetic activation and parasympathetic withdrawal, as could be expected. Subjective reports of progressing symptoms are still likely to be the most reliable way of assessing motion sickness.

“…About 2/3 of all people have ever suffered specifically from carsickness, of which about half have even vomited (Reason & Brand, 1975;Griffin, 1990). Incongruences between what we feel and what we see typically aggravates symptoms (such as below deck at sea, or when reading a book in a car), whereas looking at the Earth-fixed horizon, even when this is presented artificially, may be beneficial (Bos et al, 2008a;Feenstra et al, 2011;Tal et al, 2012). Yet, functioning organs of balance within our inner ears, also referred to as vestibular end organs, are crucial; people without do not suffer from any kind of motion sickness.…”

This paper discusses the predicted increase in the occurrence and severity of motion sickness in selfdriving cars. Self-driving cars have the potential to lead to significant benefits. From the driver's perspective, the direct benefits of this technology are considered increased comfort and productivity. However, we here show that the envisaged scenarios all lead to an increased risk of motion sickness. As such, the benefits this technology is assumed to bring may not be capitalised on, in particular by those already susceptible to motion sickness. This can negatively affect user acceptance and uptake and, in turn, limit the potential socioeconomic benefits that this emerging technology may provide. Following a discussion on the causes of motion sickness in the context of self-driving cars, we present guidelines to steer the design and development of automated vehicle technologies. The aim is to limit or avoid the impact of motion sickness and ultimately promote the uptake of self-driving cars. Attention is also given to less well known consequences of motion sickness, in particular negative aftereffects such as postural instability, and detrimental effects on task performance and how this may impact the use and design of self-driving cars. We conclude that basic perceptual mechanisms need to be considered in the design process whereby self-driving cars cannot simply be thought of as living rooms, offices, or entertainment venues on wheels.
