This review investigated virtual reality and augmented reality (VR/AR) communication interventions for children, adolescents, and adults with communication disability and neurodevelopmental disorders, as well the feasibility of these technologies. A search of five scientific databases yielded 5385 potentially relevant records of which 69 met inclusion criteria. Studies reported on a wide range of VR/AR devices, platforms, and applications for people with autism spectrum disorder, communication disorders, and intellectual disability. Some VR/AR systems hosted effective communication interventions; however, participant outcomes varied across the included studies. Most participants with neurodevelopmental disorders and their supporters were able to access learning experiences using VR/AR and few adverse effects were reported. Directions for future research are discussed.
