 The study aims to develop and apply a metaverse-based child social skills training program aimed at improving the social interaction abilities of children with ASD, age 7 to 12 years. The treatment group will participate in the metaverse-based social skills training program developed by this research team, once a week for 60 minutes per session for four weeks, while the control group will not intervene during the experiment. The study is expected to recruit and enroll participants in March 2022, and will be conducted from March 2022 to May 2022. The metaverse-based program offers excellent accessibility and is inexpensive because it can be administered at home. And if a method can be applied to detect children's emotional changes early using biometric information collected through wearable devices, then emotional changes such as anxiety and anger can be alleviated in advance, thus reducing issues in children with ASD.
