Children with autism spectrum disorder (ASD) show reduced gaze to social partners. Eye contact during live interactions is often measured using stationary cameras that capture various views of the child, but determining a child's precise gaze target within another's face is nearly impossible. This study compared eye gaze coding derived from stationary cameras to coding derived from a "point-of-view" (PoV) camera on the social partner. Interobserver agreement for gaze targets was higher using PoV cameras relative to stationary cameras. PoV camera codes, but not stationary cameras codes, revealed a difference between gaze targets of children with ASD and typically developing children. PoV cameras may provide a more sensitive method for measuring eye contact in children with ASD during live interactions.
患有自闭症谱系障碍（ASD）的儿童对社交伙伴的注视减少。在实时互动中，眼神接触通常使用固定摄像头来测量，这些摄像头可以捕捉孩子的各种视角，但要确定孩子在他人脸上的确切注视目标几乎是不可能的。本研究将固定摄像头得出的目光注视编码与社交伙伴身上的“视角”（PoV）摄像头得出的编码进行了比较。相对于固定摄像头，使用PoV摄像头时，观察者间对注视目标的一致性更高。PoV摄像头编码而非固定摄像头编码揭示了患有ASD的儿童与发育正常儿童的注视目标之间存在差异。PoV摄像头可能为测量患有ASD的儿童在实时互动中的眼神接触提供一种更灵敏的方法。
