晕动症仍然是长时间舒适使用虚拟现实（VR）的主要障碍之一，然而，由于晕动症的发作和进展在不同个体间存在显著差异，其时间发展过程仍未被充分理解。眼动追踪提供了一种连续且非侵入性的用户行为测量手段，非常适合研究用户在VR暴露期间的反应。然而，现有工作主要集中于聚合注视指标或暴露后评估，导致早期眼动动态与不适进展之间的关系尚未得到充分探索。在本文中，我们研究了早期眼动动态是否能表征后续晕动症的进展。利用VR暴露前1至5分钟内计算的注视持续时间、注视离散度、扫视幅度、扫视速度和注视偏心率的轨迹，我们评估了这些指标与后续不适进展的关联，并比较了暴露后晕动症严重程度低和高的参与者之间的早期注视动态。我们的结果表明，早期注视离散度与后续不适进展持续相关，而晕动症严重程度组之间未观察到显著差异。这些发现表明，早期注视离散度可以表征不适的进展，而非最终的晕动症严重程度。总体而言，这项工作为早期眼动行为与晕动症进展之间的时间关系提供了新的见解，有助于理解沉浸式体验中的注视动态。
英文摘要
Cybersickness remains one of the primary barriers to prolonged and comfortable virtual reality (VR) use, yet the temporal development of cybersickness remains poorly understood because its onset and progression vary substantially across individuals. Eye tracking provides a continuous and unobtrusive measure of user behavior, making it well suited for investigating how users respond throughout VR exposure. However, existing work has mainly focused on aggregate gaze measures or post-exposure assessments, leaving the relationship between early eye-movement dynamics and discomfort progression underexplored. In this paper, we investigate whether early eye-movement dynamics characterize the subsequent progression of cybersickness. Using trajectories of fixation duration, fixation dispersion, saccade amplitude, saccade velocity, and gaze eccentricity computed over the first one to five minutes of VR exposure, we evaluate their association with subsequent discomfort progression and compare early gaze dynamics between participants with low and high post-exposure cybersickness severity. Our results show that early fixation dispersion is consistently associated with subsequent discomfort progression, whereas no significant differences are observed between cybersickness severity groups. These findings suggest that early fixation dispersion can characterize the progression of discomfort rather than the final cybersickness severity. Overall, this work provides new insight into the temporal relationship between early eye-movement behavior and cybersickness progression, contributing to the understanding of gaze dynamics during immersive experiences.
