Abstract Cybersickness is common during head-mounted display (HMD) based virtual reality. This study examined whether it is possible to: (1) identify people who are more susceptible to this cybersickness; and (2) find general ways to reduce its occurrence and severity. Our participants were exposed to HMD-based virtual reality four times over two different days (using “Freedom Locomotion VR”). During these 10-min trials, participants were either free-standing or posturally restrained as they actively controlled or passively viewed their locomotion through the virtual environment. Cybersickness was found to increase steadily over time during each exposure. While this cybersickness was markedly reduced on day 2 (compared to day 1), it was not significantly altered by either the use of postural restraints or active locomotion control. However, the sick and well participants in our study were found to differ in terms of their spontaneous postural activity (before they entered virtual reality). We found that the participants who experienced stronger vection also tended to report more severe cybersickness in this study. These findings suggest that we should be able to identify people who are more susceptible to cybersickness and help them become more resistant to it (via repeated exposures to HMD-based virtual reality).

姿势稳定性、主动控制、暴露持续时间和重复暴露对 HMD 诱发的网络病的影响

摘要 网络病在基于头戴式显示器（HMD）的虚拟现实中很常见。这项研究检查了是否有可能：(1) 识别更容易感染这种网络病的人；(2) 找到减少其发生和严重程度的一般方法。我们的参与者在两天内四次接触基于 HMD 的虚拟现实（使用“Freedom Locomotion VR”）。在这 10 分钟的试验中，参与者在虚拟环境中主动控制或被动观察自己的运动时，要么是独立站立，要么是姿势受到限制。在每次暴露期间，发现网络病随着时间的推移稳步增加。虽然这种网络病在第 2 天（与第 1 天相比）显着减少，但使用姿势约束或主动运动控制并没有显着改变。然而，我们研究中的病人和健康参与者被发现在他们的自发姿势活动方面有所不同（在他们进入虚拟现实之前）。我们发现，在这项研究中，经历过更强逆流的参与者也倾向于报告更严重的网络病。这些发现表明，我们应该能够识别出更容易患网络病的人，并帮助他们增强抵抗力（通过反复接触基于 HMD 的虚拟现实）。
