The risk of motion sickness is considerably higher in autonomous vehicles than it is in human-operated vehicles. Their introduction will therefore require systems that mitigate motion sickness. We investigated whether this can be achieved by augmenting the vehicle interior with additional visualizations. Participants were immersed in motion simulations on a moving-base driving simulator, where they were backward-facing passengers of an autonomous vehicle. Using a Head-Mounted Display, they were presented either with a regular view from inside the vehicle, or with augmented views that offered additional cues on the vehicle’s present motion or motion 500ms into the future, displayed on the vehicle’s interior panels. In contrast to the hypotheses and other recent studies, no difference was found between conditions. The absence of differences between conditions suggests a ceiling effect: providing a regular view may limit motion sickness, but presentation of additional visual information beyond this does not further reduce sickness.

自动驾驶汽车发生晕动病的风险远高于人工驾驶汽车。因此，它们的引入将需要减轻晕动病的系统。我们调查了这是否可以通过使用额外的可视化来增强车辆内部来实现。参与者沉浸在移动基础驾驶模拟器上的运动模拟中，他们是自动驾驶汽车的后向乘客。使用头戴式显示器，他们可以看到车辆内部的常规视图，或者提供有关车辆当前运动或未来 500 毫秒运动的额外线索的增强视图，显示在车辆的内部面板上。与假设和其他最近的研究相反，条件之间没有发现差异。
