摘　　要：晕动症是制约虚拟现实技术发展的重要因素之一,目前关于虚拟现实晕动症的研究大多基于静态或者运动仿真平台,极少在真实运动状态下进行研究。为了研究真实运动状态下的晕动症,设计了一套虚拟现实系统并对虚拟现实晕动症进行评测。系统使用头盔显示器和一辆可以实时采集运动状态的车辆,让参与者在实验过程中看到与真实运动状态一致的虚拟场景。通过主观和客观的对比实验对参与者在视觉和前庭感知冲突的条件下产生的晕动症程度进行了评价。实验结果表明,运动状态与视觉状态是否一致对虚拟现实晕动症有很大的影响,用户在使用系统时的晕动症程度会随着真实运动状态与视觉一致性的减小而提升,在极端条件下可产生用户无法承受的生理不适状况。The cybersickness is still a huge obstacle for virtual reality（VR） system. Current researches on cybersickness are mostly based on static or dynamic simulators, while studies in the real movement state is rare. An evaluating system which employed a head-mounted display（HMD） with a running vehicle was proposed to study the cybersickness in the real movement state. In this system, users sitting in the vehicle could see virtual scenes which was consistent with the real motion through the HMD. Subjective and objective evaluating experiments were proposed to analyze the different levels of the cybersickness caused by visual-vestibular conflict. The results show that the consistency of real movement and visually perceived movement have a great impact on cybersickness. Cybersickness gets worse when the consistency decreases. Serious cybersickness may lead to extreme situation where the discomfort may not be afforded by users.
