Description

Children with Autism Spectrum Disorder (ASD) face challenges in social communication and interaction that may be helped through computer-based intervention. Earlier studies report oddity as lack of natural traits in facial expressions of affected individuals. This project develops a novel hardware-software platform intended for use in future intervention paradigms targeting facial oddity biomarkers. Real-time recognition of the basic facial expressions—happy, sad, anger, fear, surprise, and disgust—plus neutral is achieved using a deep artificial neural network modeled using the Tensorflow machine intelligence library. The network is trained and tested on the Extended Cohn-Kanade (CK+) facial expression dataset, then deployed in a real-time software application that processes and labels facial expressions frame-by-frame from live video feed. The application is written and interfaced with the NAO robot using the Python programming language. The resulting hardware-software platform is planned for future studies of the efficacy of robot-mediated intervention in children with ASD.
