The potential of technology-based interventions for children with autism spectrum disorder (ASD) has received significant attention in recent years. In particular, immersive and interactive technologies such as virtual reality (VR) are being compared with traditional approaches. VR interventions claim to bring a richer experience to children with ASD. However, with it comes the potential risk of more sensory stimulation. The existing evaluations are focused on user evaluation, and then there is a gap in the expert evaluation of the autism intervention system to appropriately inform the design of such interventions. In this paper, the author proposes an expert evaluation-based method to conduct a comprehensive test of autism intervention systems.
