Comparison of different methods for categorizing the individual susceptibility to motion sickness - A carsickness study.

In studies aimed at developing avoidance strategies to reduce motion sickness (kinetosis) in autonomous vehicles, failing to account for the wide variability in individual kinetosis susceptibility can lead to inaccuracies and disregard effective countermeasures. Three methods for assessing individual susceptibility to carsickness - two questionnaires focusing on kinetosis experiences and a kinetosis-provoking lab test - were compared with the development of kinetosis during real car driving tests. Questions about car-specific kinetosis-provoking situations (MS-C) exhibit stronger correlations with kinetosis in car experiments compared to the commonly used questions about kinetosis experiences across different types of transportation (MS-VD).
