Recent years, applications of virtual reality technology and cognitive science have provided many inestimable insights into the treatment of children with autism spectrum disorder (ASD). In this review, we focus on research that has used VR to intervent and improve performance on some disorders of children with autism. We review interventions with VR technology that target three disorders of ASD children: (1) social communication competence, (2) emotion recognition, and (3) behavior and cognition. Despite encouraging preliminary results, the use of VR technology and cognitive science still remains limited. Hence, systematic research and studies combined with other modern technologies, such as eye-tracking technologies are in urgent need. We also discuss key issues and promising directions in treatment of autistic children for future research.
