Beyond Seasickness: A Motivated Call for a New Motion Sickness Standard across Motion Environments

Motion sickness is known under several names in different domains, such as seasickness, carsickness, cybersickness, and simulator sickness. As we will argue, these can all be considered manifestations of one common underlying mechanism. In recent years, it has received renewed interest, largely due to the advent of automated vehicles and...

Optimising human performance by reducing motion sickness and enhancing situation awareness with an artificial 3D Earth-fixed visual reference

Human performance has been shown to be negatively correlated with seasickness. By reducing crew, ship size, and hence redundancy, sickness induced risks increase exponentially. Although medication is effective, it also causes drowsiness. Non-pharmacological countermeasures are scarce, the most popular one being to look at the horizon. We...

Reduced seasickness by an artificial 3d earth-fixed visual reference

Motion sickness is generally caused by not being able to correctly estimate one’s self-motion. In the case of crew in, e.g., the command centre of a naval vessel, a nauseating conflict exists between what they see (the stable interior of the ship) and what they feel (the motion of the ship). To reduce the conflict, we designed and tested an ...

Fainting passengers: The role of cabin environment

Reported percentages of in-flight medical incidents caused by syncope, the medical term for fainting, vary between 15 % and 22 %. Syncope is usually a benign medical event, but it may cause fear and distress among passengers and the individual involved. Incorrectly diagnosed benign syncope may lead to unnecessary flight diversions. In this...

Fluid loss does not explain coagulation activation during air travel

The mechanism of air travel-related venous thrombosis is unclear. Although immobility plays a pivotal role, other factors such as fluid loss may contribute. We investigated whether fluid loss occurred more in individuals with coagulation activation after air travel than in subjects without. As a secondary aim, we investigated whether fluid loss...

Middelen tegen bewegingsziekte: effectiviteit en veiligheid

Inleiding Een aanzienlijk aantal militaire leerling-vliegers krijgt in de loop van de opleiding last van bewegingsziekte tijdens trainingsvluchten. Voor een aantal leerlingen is het probleem zo ernstig, dat zij een desensitisatiebehandeling moeten ondergaan. Wanneer het zou lukken de symptomen m.b.v. anti-bewegingsziektemiddelen te reduceren,...

Susceptibility to seasickness

This paper explains part of the observed variability in passenger illness ratings aboard ships by gender, age and sickness history. Within the framework of a European project, 2840 questionnaires, gathered on several ships operating all over Europe, were analysed. Gender, age and sickness history all had a highly significant effect on...

Motion sickness symptoms in a ship motion simulator: Effects of inside, outside, and no view

Vehicle motion characteristics differ between air, road, and sea environments, both vestibularly and visually. Effects of vision on motion sickness have been studied before, though less systematically in a naval setting. It is hypothesized that appropriate visual information on self-motion is beneficial in a naval setting and that task...

Latest insight in the causes of motion sickness

Uit alle theorieën over bewegingsziekte komt de subjecieve verticale mismatch theorie als beste naar voren.

Prediction of seasickness with more than one degree of freedom

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...
