We investigated whether motion sickness analogous to carsickness can be studied in a moving base simulator, despite the limited motion envelope. Importantly, to avoid simulator sickness, vision outside the simulator cabin was restricted. Participants (N = 16) were exposed blindfolded to 15-min lateral sinusoidal motion at 0.2 Hz and 0.35 Hz on separate days. These conditions were selected to realize optimal provocativeness of the stimulus given the simulator's maximum displacement and knowledge on frequency-acceleration interactions for motion sickness. Average motion sickness on an 11-point scale was 2.21 ± 1.97 for 0.2 Hz and 1.93 ± 1.94 for 0.35 Hz. The motion sickness increase over time was comparable to that found in studies using actual vehicles. We argue that motion base simulators can be used to incite motion sickness analogous to carsickness, provided considerable restrictions on vision. Future research on carsickness, potentially more prevalent in autonomous vehicles, could benefit from employing simulators.
我们研究了在运动基座模拟器中是否可以研究类似于晕车的运动病，尽管运动范围有限。重要的是，为了避免模拟器病，限制了模拟器舱外的视野。参与者（N=16）在分开的日子里蒙住眼睛分别暴露于 0.2 Hz 和 0.35 Hz 的 15 分钟侧向正弦运动中。这些条件是根据模拟器的最大位移和对运动病的频率-加速度相互作用的了解选择的，以实现刺激的最佳激发性。0.2 Hz 时的平均运动病评分为 2.21±1.97，0.35 Hz 时为 1.93±1.94。随着时间的推移，运动病的增加与使用实际车辆进行的研究中发现的情况相当。我们认为，只要对视觉进行相当大的限制，运动基座模拟器就可以用于引发类似于晕车的运动病。未来对在自动驾驶汽车中更普遍的晕车的研究可能会受益于模拟器的使用。
