Research On Virtual Driving Rehabilitation Training And Quantitative Evaluation System For Autistic Children

With the progress of information technology,the collaboration of different technology systems and clinical practices has promoted the development of the health industry and provided patients with better rehabilitation experience.However,the application of information technology in the field of neurological rehabilitation still has certain limitations,especially in the field of rehabilitation of autistic children.Although advanced international studies constantly show that the new generation of information technology can provide a new opportunity for the rehabilitation of autistic children,there are still some problems in the practical application process that cannot be ignored: first,the application of technology in children lacks a rigorous design strategy,resulting in the neglect of user feelings,and the formulation of design programs lacks of standardization and science.Second,autistic children’s manifestations involve multiple levels of expression,such as attention and behavior.Subjective and qualitative diagnosis and single technical equipment cannot form effective attention to the condition.Thirdly,autism is highly heterogeneous,and fixed rehabilitation modes cannot meet the diverse rehabilitation trajectories of patients.The rehabilitation of autistic patients has a great impact on family happiness and social stability.Therefore,facing the rehabilitation problems and challenges of autistic patients in the information age,it is of great practical significance to design a human-computer interactive rehabilitation training product that integrates assessment and personalized intervention.In view of the above problems,the main work of this thesis is reflected in the following points:1)Through literature research,the rehabilitation mechanism and development bottleneck of autistic children were clarified,and on this basis,the user needs were investigated.Based on user needs and the multi-sensory channel theory,a multi-sensory case study was carried out on 20 patients.According to the results of the case study,it was found that in this mode of rehabilitation,channels in two brain regions of patients showed significant activation.A virtual driving rehabilitation training system for autistic children was proposed by interpreting the characteristics and connections between user needs and multi-sensory channel theory.The design process starts from the needs of users and improves the normativity and scientific of the human-computer interaction design scheme for autistic children.2)Unity3D software was used to carry out human-computer interaction design of virtual driving rehabilitation training system for autistic children.Centering on scene design and function design,a rehabilitation training mode of "motion + perception" was constructed.In addition,cognitive and social guidance and other rehabilitation tasks were integrated into the system construction process to enrich the learning activities and learning situations of autistic children.After the initial construction of the system was completed,the local children’s rehabilitation medical center carried out a functional test,and based on the test results,the system was improved.3)A multi-modal data quantization and output framework is proposed.Physiological data,behavioral data and game data of patients undergoing virtual driving rehabilitation training are collected by means of near-infrared brain functional imaging system,visual sensors and steering wheel sensors to enhance the dimension of data evaluation.Through the synchronous data collection of three dimensions,the subjectivity of scale evaluation and the limitation of single device evaluation dimension are overcome.Combined with the quantitative output and analysis results of data,the development of rehabilitation strategies for physicians is assisted,and the data connection from the data end to the application end is enhanced.4)A systematic test experiments were carried out on 12 autistic children in rehabilitation centers.Based on the virtual driving rehabilitation training system and the multi-modal data quantization and output framework,the data of patients with different degrees of disease were quantified and output.The fun and rehabilitation of the system were evaluated through the quantitative indicators.The results showed that 83% of the test patients could maintain the training concentration for more than half of the time during the training process.81% of the patient’s brain regions showed positive activation,and a score of 71 on the system Availability scale indicated high acceptance of the system among users.Based on the new generation of information technology,this study constructed a five-inone rehabilitation application system for autistic children from "mechanism-strategy-design-verification-evaluation intervention",and enhanced scientific and personalized intervention for patients’ conditions through multidisciplinary cooperation.The research organically combines the rehabilitation training methods and data evaluation methods in the rehabilitation process of autistic children.Using the human-computer interactive virtual driving rehabilitation training system as the carrier,it adopts non-invasive means to acquire multidimensional data of patients,which enhances the interest of autistic children in rehabilitation,promotes the rehabilitation effect of patients,and enhances the interpretation of patients’ heterogeneous conditions.It provides more possibilities for the formulation of individual and common rehabilitation programs for patients,and provides necessary references for the research of rehabilitation strategies and assisted rehabilitation interventions for autistic children while verifying the availability of the system.
