Importance of Detecting Facial Expressions to Differentiate Typical Vs. ASD Children: Comparative Study

Understanding and interpreting facial expressions is a cornerstone of effective social communication. For typically developing children, reading subtle expressions like joy, fear, or surprise unfolds naturally during social interactions. However, in children with autism spectrum disorder (ASD), this intuitive process can be significantly impaired, leading to challenges in peer engagement, emotional understanding, and social reciprocity. Research indicates that approximately 30% of individuals with ASD struggle with accurate facial expression recognition, often leading to misunderstandings and withdrawal in social contexts [1]. This difficulty directly impacts early childhood, a critical social and emotional development phase. Interventions that improve facial expression recognition can dramatically enhance social interactions and quality of life for ASD children. For example, a recent study introduced a real-time vibrotactile and visual feedback translator, helping adults with ASD identify seven core emotions—achieving successful learning in as little as 19 minutes [2]. The key to such assistive systems lies in accurately extracting emotional cues from facial images, highlighting
