Autistic Children Attention Training System Based On Augmented Reality Technology

Attention is the background condition for the occurrence of all cognitive activities.Without attention to participation,no activity can be maintained and carried out.Autistic children usually have serious deficiencies in the aspects of exercise,perception,emotional understanding and expression,and the selective function,maintenance function,and regulation and supervision of attention directly affect the normal process of sensation,memory,thinking and so on.It is very important for children with attention to be attentive.Based on the attentional network theory proposed by Posner,specific training can affect the attention network of children with attention disorders and normal children.The commonly used attention training methods include: drug intervention methods,behavior methods,sensory integration training methods,biofeedback training methods,and computer software training methods.Although the role of drug intervention is obvious,taking drugs for a long time has an impact on the healthy growth of children;the behavioral methods are not ideal for children with autism,and can only improve one aspect of the children;sensory integration training is affected by many factors such as the venue.Limits,but also have the disadvantage of long training time;biofeedback training currently does not take into account the training of individual differences in targeted training;and computer software training is the traditional task of attention training transplanted to the computer,but many software It is just a simple computer instead of paper and pen operation.The training elements are simple,and there is not much innovation in the task design.In view of the above problems,this topic mainly studies the attention training system of autistic children based on augmented reality technology.The system uses the Kinect sensor to acquire depth images,acquires the required image of the system through the target recognition and tracking algorithm,after the Unity3 D platform fusion rendering,the training task is presented to the children with autism in the form of games,and finally the system uploads all the training data to the cloud server.Save it.This topic applies the system to the intervention process of autistic children and examines their effect on the improvement of attention level.This article first introduced the research background of the topic,and introduced the research status of attention training,researched the research situation at home and abroad,and proposed this article’s attention training system for autistic children based on augmented reality technology.Afterwards,this paper analyzes and designs each module of the attention training system.It describes in detail the client design and implementation of the attention training system,including the depth image preprocessing,target recognition and tracking algorithm and image rendering fusion technology.The task of attention training was introduced in detail.The task design and interaction methods of class and greedy snakes were introduced.Then,the design of the system server was introduced in detail,including business logic processing,data logic processing and database design.Finally,the attention training system developed in this project was applied to the intervention training for autistic children.After one month of intervention training,the data before and after the intervention were statistically analyzed,and the experimental results were explored to prove that the training of the system was reasonable and effective.expected result.In summary,the system has realized the training of the Internet.Through natural humancomputer interaction,children’s selective attention and continuous attention level can be effectively improved.The research results obtained in this topic are the methods of attention training in the future.The means and methods provide certain practical value and reference significance,and demonstrate the bright application prospects of augmented reality technology in children’s development and other fields.
