Driving simulator usage is often accompanied by motion sickness, and techniques for its prevention are not yet established. To reduce visually induced motion sickness (VIMS), we investigated the effects of synchronised presentation of engine sounds and motorcycle vibration on VIMS. A total of 80 participants experienced a driving scene with a head-mounted display for 5 minutes with or without synchronised presentation of engine sound and vibration. The results showed that VIMS scores, as measured by the Fast Motion Sickness scale, were significantly lower in participants who experienced the driving scene with sounds and vibration than in those who experienced the scene with sounds only, vibration only, or neither. Multiple regression analyses revealed that susceptibility to VIMS consistently explained the severity of VIMS to some extent but not with perceived realism of the virtual reality (VR) scene, sex, and experiences about VR devices and vehicles. This study demonstrated that simultaneous presentation of engine sounds and vibration, which were synchronous to each other and tightly coupled with the visual flow speed, effectively reduces VIMS while experiencing motorcycling simulators. The findings not only improve practical knowledge for reducing VIMS in driving simulators but also provide evidence for understanding the mechanisms of VIMS.
驾驶模拟器的使用常常伴随着晕车，而预防晕车的技术尚未建立。为了减少视觉诱导的晕车（VIMS），我们研究了同步呈现发动机声音和摩托车振动对 VIMS 的影响。共有 80 名参与者在头戴式显示器上体验了 5 分钟的驾驶场景，同时或不同时呈现发动机声音和振动。结果表明，在经历了声音和振动的驾驶场景的参与者中，VIMS 评分（通过快速晕车量表测量）明显低于仅经历声音、仅经历振动或两者都不经历的参与者。多元回归分析表明，晕车易感性在一定程度上始终可以解释 VIMS 的严重程度，但不能解释虚拟现实（VR）场景的感知真实性、性别以及对 VR 设备和车辆的体验。这项研究表明，同时呈现彼此同步且与视觉流速紧密耦合的发动机声音和振动，可以有效地减少驾驶模拟器中体验摩托车时的 VIMS。研究结果不仅提高了在驾驶模拟器中减少 VIMS 的实用知识，还为理解 VIMS 的机制提供了证据。
