Study On Application Of Virtual Reality Technology In Intervention Of Social Emotional Ability Of Autistic Children

Autism Spectrum Disorder(ASD)is a kind of Neurodevelopmental Disorder,whose core symptoms are social communication and social interaction deficits,narrow interests and stereotypes.The development of social emotional ability of autistic children is the basis of their good interaction with others,and also the core of their social deficiencies.At present,the means and courses in the field of social emotional ability training for normal children are quite mature,but these interactive carriers,which mainly consist of card exchange,story creation,role playing and group games,rely heavily on the development of children’s psychological theory and environmental imagination abilities.These abilities are precisely the core abilities that autistic children lack,so the commonly used interventions are not very suitable for children with autism.Virtual reality technology can create a realistic virtual environment with immersive and interactive characteristics.It can let autistic children "see" the world with their own eyes,without imagination and relying on the development of children’s basic abilities.It is a valuable exploration direction in the field of intervention of social emotional abilities of autistic children.Based on the above theory,this project develops a social emotional ability intervention system for autistic children based on virtual reality technology.Through the Unity3 D platform,it creates vivid ocean scenes and develops interactive programs.Kinect sensor is used to collect children’s action information,and dolphin virtual role is used to interact with autistic children to guide children to complete the game tasks in the default situation.In order to verify the effectiveness of the system,16 children with high-functioning autism were selected and divided into two groups after matching.8 children in each group were trained for two months in the experimental group.The results of the intervention were analyzed with the evaluation data of the control group.It was found that there were significant differences in the social emotional ability of autistic children in the experimental group before and after the intervention.In summary,the system realizes the Internet-based training and immersive,unburdened human-computer interaction,which proves the feasibility and effectiveness of introducing virtual reality technology into the field of social emotional ability intervention for autistic children.The research results of this intervention vector provide certain reference significance and practical value for further research in the field,and show the bright application prospect of virtual reality technology in the field of children development.
