患有自闭症谱系障碍（ASD）的儿童在产生和感知情感面部表情方面存在困难。他们的表情通常被成年人视为非典型。本文重点研究了数据驱动的方法来分析和量化ASD儿童面部表情的相似性。我们的目标是揭示这些特征的面部表情，诱导感知的相似性的观察者。使用一个精心收集的动作捕捉数据库，面部表情的儿童和没有ASD进行比较，在六个基本的情感类别，采用信息论，时间序列建模和统计分析的方法。我们的实验表明，ASD儿童通常具有不太复杂的表达产生机制; ASD儿童和非ASD儿童之间的面部动力学差异主要来自眼部区域。我们的研究还指出，ASD儿童的左右区域对称性较低，面部区域运动强度的变化较小。
Children with Autism Spectrum Disorder (ASD) are known to have difficulty in producing and perceiving emotional facial expressions. Their expressions are often perceived as atypical by adult observers. This paper focuses on data driven ways to analyze and quantify atypicality in facial expressions of children with ASD. Our objective is to uncover those characteristics of facial gestures that induce the sense of perceived atypicality in observers. Using a carefully collected motion capture database, facial expressions of children with and without ASD are compared within six basic emotion categories employing methods from information theory, time-series modeling and statistical analysis. Our experiments show that children with ASD usually have less complex expression producing mechanisms; the differences in facial dynamics between children with and without ASD primarily come from the eye region. Our study also notes that children with ASD exhibit lower symmetry between left and right regions, and lower variation in motion intensity across facial regions.
