This study investigated the effects of the time interval between virtual reality (VR) sessions on visually induced motion sickness (VIMS) reduction to better understand adaptation to and recovery from a nauseating VR experience. The participants experienced two 6-min VR sessions of a first-person motorcycle ride through a head-mounted display with (1) a 6-min interval, (2) an interval until the VIMS score reached zero, and (3) a 60-min interval. The results showed that for each condition, VIMS in the second session was aggravated, unchanged, or attenuated, respectively, indicating that additional resting time was necessary for VIMS adaptation. This study suggests that a certain type of multisensory learning attenuates VIMS symptoms within a relatively short time, requiring at least 20 min of additional resting time after subjective recovery from VIMS symptoms. This finding has important implications for reducing the time interval between repeated challenges when adapting to nauseating stimuli during VR experiences.
本研究旨在探讨虚拟现实 (VR) 体验之间的时间间隔对视觉诱发运动病 (VIMS) 缓解的影响，以便更好地了解对令人恶心的 VR 体验的适应和恢复。参与者通过头戴式显示器体验两轮 6 分钟的第一人称摩托车骑行，分别为：（1）两轮之间有 6 分钟的间隔；（2）间隔至 VIMS 评分降至零；（3）两轮之间有 60 分钟的间隔。结果表明，在每种情况下，第二轮的 VIMS 分别加重、不变或减轻，表明 VIMS 适应需要额外的休息时间。本研究表明，某种类型的多感觉学习在相对较短的时间内减轻 VIMS 症状，在主观缓解 VIMS 症状后至少需要 20 分钟的额外休息时间。这一发现对于减少在 VR 体验中适应令人恶心的刺激时，重复挑战之间的时间间隔具有重要意义。
