视觉诱导晕动症(VIMS)是虚拟现实(VR)体验过程中可能产生的一种常见症状,该症状严重降低了用户的体验的舒适度,阻碍了VR技术的推广和发展。虚拟空间畸变是影响VR体验舒适度的潜在因素之一,近眼显示设备不完全的畸变校正会产生虚拟空间畸变,进而可能引发VIMS。针对虚拟空间畸变对VIMS的影响程度,本文模拟VR技术的体验过程,对以VR技术为代表的近眼显示技术畸变机理进行分析,设计了3个不同畸变参数下VIMS等级评价的视觉感知实验,并对实验的主客观数据进行统计分析。结果表明,虚拟空间畸变对VIMS症状具有显著性影响,受测者观看立体影像的畸变程度越大,所引起的VIMS症状越明显。该研究可为VR技术体验的舒适度提升方向提供理论依据。
Visually induced motion sickness (VIMS) is a common symptom in the process of experiencing virtual reality (VR), which seriously reduces the comfort of users’ VR experience and hinders the promotion and development of VR technology. Virtual space distortion is one of the potential factors affecting the comfort level of the VR experience. Incomplete distortion correction of near-eye display equipment will produce virtual space distortion, which may leads to VIMS. Aiming at the influence degree of virtual space distortion on VIMS, this paper simulated the experience process of VR technology, analyzed the distortion mechanism of near-eye display technology represented by VR technology, designed visual perception experiments of VIMS grade evaluation under three different distortion parameters, and carried out detailed subjective and objective data statistical analysis. The results show that virtual space distortion has a significant impact on VIMS symptoms, the greater the degree of distortion of the stereoscopic images viewed by the subjects, the more obvious the symptoms of VIMS. This study can provide a theoretical basis for improving the comfort level of the VR technology experience.
