Humans are constantly presented with rich sensory information that the central nervous system (CNS) must process to form a coherent perception of the self and its relation to its surroundings. While the CNS is efficient in processing multisensory information in natural environments, virtual reality (VR) poses challenges of temporal discrepancies that the CNS must solve. These temporal discrepancies between information from different sensory modalities leads to inconsistencies in perception of the virtual environment which often causes cybersickness. Here, we investigate whether individual differences in the perceived relative timing of sensory events, specifically parameters of temporal-order judgement (TOJ), can predict cybersickness. Study 1 examined audiovisual (AV) TOJs while Study 2 examined audio-active head movement (AAHM) TOJs. We deduced metrics of the temporal binding window (TBW) and point of subjective simultaneity (PSS) for a total of 50 participants. Cybersickness was quantified using the Simulator Sickness Questionnaire (SSQ). Study 1 results (correlations and multiple regression) show that the oculomotor SSQ shares a significant yet positive correlation with AV PSS and TBW. While there is a positive correlation between the total SSQ scores and the TBW and PSS, these correlations are not significant. Therefore, although these results are promising, we did not find the same effect for AAHM TBW and PSS. We conclude that AV TOJ may serve as a potential tool to predict cybersickness in VR. Such findings will generate a better understanding of cybersickness which can be used for development of VR to help mitigate discomfort and maximize adoption.

人类不断获得丰富的感官信息，中枢神经系统 (CNS) 必须处理这些信息以形成对自我及其与周围环境关系的连贯感知。虽然中枢神经系统在处理自然环境中的多感官信息方面非常有效，但虚拟现实 (VR) 提出了中枢神经系统必须解决的时间差异的挑战。来自不同感官模式的信息之间的这些时间差异导致对虚拟环境的感知不一致，这通常会导致晕机症。在这里，我们调查感知到的感觉事件相对时间的个体差异，特别是时间顺序判断 (TOJ) 的参数，是否可以预测晕机症。研究 1 检查视听 (AV) TOJ，而研究 2 检查音频活动头部运动 (AAHM) TOJ。我们为总共 50 名参与者推导出时间绑定窗口 (TBW) 和主观同时性点 (PSS) 的指标。Cyber​​sickness 使用模拟器疾病问卷 (SSQ) 进行量化。研究 1 结果（相关性和多元回归）表明动眼神经 SSQ 与 AV PSS 和 TBW 具有显着但正相关。虽然 SSQ 总分与 TBW 和 PSS 之间存在正相关关系，但这些相关性并不显着。因此，尽管这些结果很有希望，但我们没有发现 AAHM TBW 和 PSS 具有相同的效果。我们得出结论，AV TOJ 可以作为预测 VR 晕机症的潜在工具。这些发现将使人们更好地理解晕机症，从而可以将其用于 VR 的开发，以帮助减轻不适感并最大限度地提高采用率。
