Cybersickness涉及虚拟现实（VR）沉浸期间可能发生的所有不良影响，这些影响可能会影响用户体验的质量，并限制VR系统的可用性，功能和使用时间。标准化的协议有助于检测可能导致多个用户晕电脑的刺激，但不能完全区分哪些特定的用户体验晕电脑。在用于监测个人电脑病的生物计量措施中，心率变异性（HRV）是以前工作中使用最多的指标之一。然而，这些只考虑了它的时间组成部分，并没有考虑到会话之间的休息时间，即使这些会影响用户的沉浸感。我们的分析解决了这些局限性，因为HRV的变化可以测量与360视频中诱导的初始晕机刺激相关的不适或“警觉性”的特定水平。首先，我们的实证结果表明，在反应晕电刺激的HRV的频率成分的显着差异。这些初始测量可以与标准的主观评估协议竞争，特别是用于检测受试者是否对VR沉浸感做出反应并出现晕电症状。
Cybersickness involves all the adverse effects that can occur during a Virtual Reality (VR) immersion, which can compromise the quality of the user experience and limit the usability, functionality and duration of use of VR systems. Standardised protocols help detect stimuli that may cause cybersickness in multiple users but do not fully discriminate which specific users experience cybersickness. Of the biometric measures used to monitor cybersickness in an individual, Heart Rate Variability (HRV) is one of the most used in previous work. However, these only considered its temporal components and did not allow for rest periods between sessions, even though these can affect users’ immersion. Our analysis addresses these limitations in that changes in HRV can measure specific levels of discomfort or ”alertness” associated with the initial cybersickness stimulus induced in the 360 videos. Primarily, our empirical results show significant differences in the frequency components of HRV in response to cybersickness stimuli. These initial measurements can compete with standard subjective assessment protocols, especially for detecting whether a subject responds to a VR immersion with cybersickness symptoms.
