Display Rotation for Reducing Motion Sickness Caused by Using VR in Vehicles

Virtual Reality systems have the potential to change the way we interact with digital content in vehicles. However, wearing a VR headset in a vehicle may increase the chances of experiencing motion sickness. There is an open question as to how to convey visual motion alongside VR content to reduce motion sickness. This research explores possible countermeasures to alleviate motion sickness by delivering visual cues of physical motion through the position of virtual displays, implicitly conveying the motion without the need for additional distracting visual cues, which could alleviate motion sickness. The results showed that such visual cues significantly reduced symptoms associated with motion sickness. We expected our findings to lead to concrete suggestions to optimize VR user experiences and user comfort in vehicles.
