Long and short-term characteristics of motion sickness: a test track investigation in a passenger car.

With the development of autonomous cars, the incidence of motion sickness has increased. Current studies on the characteristics of motion sickness have primarily focused on its long-term characteristics while ignoring its short-term characteristics, especially for the reporting time of the real-time evaluation method. This study explores the long and short-term characteristics of motion sickness, and uses self-reported motion sickness ratings at the end of car motion (the high point) and 3 s after the end of motion (the low point). Motion sickness ratings increased with task vs. no-task conditions. There is no significant correction between gender and maximum motion sickness in this study. Moreover, participants with high motion sickness susceptibility experienced increased motion sickness. The difference between the low point and the high point is found to decrease as the motion sickness ratings increase. [ABSTRACT FROM AUTHOR]
