虚拟现实（VR）系统中引人注目的场景运动可能导致晕动病（即晕动病）的症状。研究人员进行了一项受试者内部实验，以研究沿不同轴的场景振荡对晕屏水平的影响。16名男性参与者被暴露在4个20分钟的VR模拟会话中。四个会话使用相同的虚拟环境，但场景沿着不同的轴振荡，即俯仰，偏航，滚动，或没有振荡（速度：30度/秒，范围：+/- 60度）。在会话期间每隔5分钟对恶心程度进行口头评分，并在会话前后使用模拟恶心问卷（SSQ）测量恶心症状。在场景振荡存在的情况下，恶心评分和SSQ评分的增加率明显高于没有振荡的情况。虽然个体参与者对包含不同旋转轴的场景振荡的VR模拟表现出不同的恶心敏感性，但在我们随机选择的16名参与者中，轴的总体影响并不显著。本文讨论了场景振荡、持续时间和参与者的主要影响及其相互作用。2001爱思唯尔科学有限公司版权所有。
Compelling scene movements in a virtual reality (VR) system can cause symptoms of motion sickness (i.e., cybersickness). A within-subject experiment has been conducted to investigate the effects of scene oscillations along different axes on the level of cybersickness. Sixteen male participants were exposed to four 20-min VR simulation sessions. The four sessions used the same virtual environment but with scene oscillations along different axes, i.e., pitch, yaw, roll, or no oscillation (speed: 30 degrees /s, range: +/- 60 degrees). Verbal ratings of the level of nausea were taken at 5-min intervals during the sessions and sickness symptoms were also measured before and after the sessions using the Simulator Sickness Questionnaire (SSQ). In the presence of scene oscillation, both nausea ratings and SSQ scores increased at significantly higher rates than with no oscillation. While individual participants exhibited different susceptibilities to nausea associated with VR simulation containing scene oscillations along different rotational axes, the overall effects of axis among our group of 16 randomly selected participants were not significant. The main effects of, and interactions among, scene oscillation, duration, and participants are discussed in the paper. (C) 2001 Elsevier Science Ltd. All rights reserved.
