Virtual vehicles (e.g., driving video games) can give rise to visually induced motion sickness. Typically, people drive virtual vehicles. In the present study, we investigated motion sickness among participants who were exposed to virtual vehicles as passengers; that is, they observed vehicle motion, but did not control it. We also asked how motion sickness and the postural precursors of motion sickness might be influenced by participants' previous experience of driving physical vehicles. Participants viewed a recording of a virtual automobile in a driving video game. Drivers were young adults with several years of experience driving physical automobiles, while non-drivers were individuals in the same age group who did not have a driver's license and had never driven an automobile. During exposure to the virtual vehicle, we monitored movement of the head and torso. The independent measures included the incidence and severity of motion sickness. After exposure to the virtual vehicle, the incidence and severity of motion sickness did not differ between Drivers and Non-Drivers. By contrast, postural movement differed between participants who later became motion sick and those who did not. In addition, during exposure to the virtual vehicle, physical driving experience was related to patterns of postural activity that preceded motion sickness. The results are consistent with the postural instability theory of motion sickness, and illuminate relations between the control of physical and virtual vehicles.
虚拟车辆（例如驾驶视频游戏）可能会引起视觉诱导的运动病。通常，人们会驾驶虚拟车辆。在本研究中，我们调查了作为乘客暴露于虚拟车辆的参与者中的运动病；也就是说，他们观察到了车辆的运动，但没有控制它。我们还询问了运动病和运动病的姿势前体如何受到参与者驾驶物理车辆的先前经验的影响。参与者观看了驾驶视频游戏中虚拟汽车的录像。驾驶员是有多年驾驶物理汽车经验的年轻人，而非驾驶员是同一年龄组中没有驾驶执照且从未驾驶过汽车的个体。在暴露于虚拟车辆期间，我们监测了头部和躯干的运动。独立的测量指标包括运动病的发生率和严重程度。暴露于虚拟车辆后，驾驶员和非驾驶员之间的运动病发生率和严重程度没有差异。相比之下，在出现运动病的参与者和没有出现运动病的参与者之间，姿势运动存在差异。此外，在暴露于虚拟车辆期间，实际驾驶经验与运动病之前的姿势活动模式有关。结果与运动病的姿势不稳定理论一致，并阐明了物理和虚拟车辆控制之间的关系。
