摘要
感兴趣区（ROI）分析是自闭症研究中基于眼动追踪发现生物标记物的标准方法。该方法根据特定区域的注视时间百分比，确定自闭症谱系障碍（ASD）患者与发育典型（TD）患者之间的组间差异。虽然功能强大，但 ROI 是根据 ET 专家对 ASD 和 TD 注视模式差异的假设期望预先确定的。信息丰富的注视模式可视化可作为一种调查工具，用于在 ASD/TD 分层中确定稳健的 ROI。临床专家的见解可以进一步提高识别准确可视化机制和精确 ROI 的几率，从而揭示 ASD 用于捕捉场景内容的策略。
Region of Interest (ROI) analysis is the standard approach for eye tracking-based biomarker discovery in autism research. The approach identifies between-group differences between individuals with autism spectrum disorder (ASD) and typically developing (TD) peers based on percentage of time spent looking at specified areas. While powerful, ROIs are predefined by ET experts’ hypothetical expectations for where ASD and TD gaze patterns should differ. Informative gaze pattern visualizations can be used as an investigatory tool to identify robust ROIs in ASD/TD stratification. Insight from expert clinicians can further improve the odds of identifying accurate visualization mechanisms and precise ROIs which would illuminate strategies used in ASD to capture scene content.
