The phenomenon of cybersickness is currently hindering the mass market adoption of head-mounted display (HMD) virtual reality (VR) technologies. This study examined the effects of dynamic field-of-view (FOV) restriction on the cybersickness generated by ecological HMD-based gameplay. Forty participants were exposed to a commercially available HMD game (Marvel Powers United VR) under both unrestricted FOV and dynamic FOV restriction conditions across three sessions. Participants had their spontaneous postural instability measured before entering VR. Then, during/following each of these 10-min exposures to HMD VR, they rated their cybersickness, vection (illusory self-motion), and feelings of presence. Individual differences in spontaneous postural instability were found to predict cybersickness during HMD VR gameplay. Cybersickness severity increased steadily over the course of each VR exposure and was significantly reduced by dynamic FOV restriction. Presence also increased steadily over the course of each VR exposure and was positively correlated with vection. We conclude that: (1) postural instability can identify people who are more susceptible to cybersickness, (2) vection can increase an HMD user’s feelings of presence, and (3) dynamic FOV restriction can serve as a viable countermeasure to cybersickness.

目前，晕车现象阻碍了头戴式显示器（HMD）虚拟现实（VR）技术在大众市场的普及。这项研究检查了动态视野（FOV）限制对基于生态HMD的游戏玩法所产生的晕机病的影响。在不受限制的FOV和动态FOV限制下，四十名参与者接触了市售的HMD游戏（Marvel Powers United VR）三个阶段的条件。参加者在进入VR之前已测量了自发的姿势不稳定性。然后，在每次10分钟的HMD VR曝光期间/之后，他们对自己的晕车病，通气（虚幻的自我运动）和临场感进行了评估。发现自发姿势不稳定性的个体差异可预测HMD VR游戏期间的网络疾病。在每次VR暴露期间，晕车病的严重程度稳步上升，而动态FOV限制显着降低了晕车的严重性。在每次VR暴露过程中，存在也稳定地增加，并且与通气正相关。我们得出的结论是：（1）姿势不稳可以识别出更容易患晕车病的人；（2）换气可以增加HMD用户的临场感；（3）动态FOV限制可以作为应对晕船病的可行对策。
