摘要

人类不断获得丰富的感官信息,中枢神经系统(CNS)必须对这些信息进行处理,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自然环境中处理多感官信息是有效的,但虚拟现实(VR)提出了中枢神经系统必须解决的时间差异挑战。这些来自不同感官模式的信息之间的时间差异导致对虚拟环境的感知不一致,这往往导致晕屏。在本研究中,我们研究了感觉事件的感知相对时间的个体差异,特别是时间顺序判断参数(TOJ)是否可以预测晕动病。研究1检查视听(AV) toj,而研究2检查听觉主动头部运动(AAHM) toj。我们推导了50名参与者的时间绑定窗口(TBW)和主观同时性点(PSS)的度量。使用模拟晕机问卷(SSQ)对晕机进行量化。研究1结果(相关和多元回归)显示,动眼肌SSQ与AV PSS和TBW呈显著正相关。虽然总SSQ得分与TBW和PSS之间存在正相关,但这些相关性并不显著。因此,虽然这些结果很有希望,但我们没有发现AAHM TBW和PSS的效果相同。我们的结论是,AV TOJ可以作为预测虚拟现实中的晕动病的潜在工具。这些发现将有助于更好地理解晕动症,这可以用于VR的开发,以帮助减轻不适并最大限度地采用。

Can the Perceived Timing of Multisensory Events Predict Cybersickness?

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.

期刊介绍: Multisensory Research is an interdisciplinary archival journal covering all aspects of multisensory processing including the control of action, cognition and attention. Research using any approach to increase our understanding of multisensory perceptual, behavioural, neural and computational mechanisms is encouraged. Empirical, neurophysiological, psychophysical, brain imaging, clinical, developmental, mathematical and computational analyses are welcome. Research will also be considered covering multisensory applications such as sensory substitution, crossmodal methods for delivering sensory information or multisensory approaches to robotics and engineering. Short communications and technical notes that draw attention to new developments will be included, as will reviews and commentaries on current issues. Special issues dealing with specific topics will be announced from time to time. Multisensory Research is a continuation of Seeing and Perceiving, and of Spatial Vision.
