Research On Design Of Hand-Eye Coordination Rehabilitation Teaching Aids For Autistic Children

Autism spectrum disorder(ASD)is a widespread neurodevelopmental disorder.With the in-depth research in the fields of medicine and special education,early intervention gradually began to show the superiority of its rehabilitation treatment effect.In the course of rehabilitation treatment,most interventions must be carried out with corresponding rehabilitation teaching aids,but the number of autism rehabilitation teaching aids available on the market is very small,which simply cannot meet the needs of a large number of teaching aids for rehabilitation training,and coordinate rehabilitation training by hand Taking the course as an example,most of the teaching aids used in the institution are made by teachers.Aiming at the problems related to hand-eye coordination in children with autism,the theoretical results of sensory integration ability,common attention,hand flexibility and hand-eye coordination ability of children with autism are studied.Conduct research on coordinated rehabilitation training courses and summarize the training points of hand-eye coordinated rehabilitation training as a theoretical basis for design research.In-depth analysis of hand-eye coordination rehabilitation teaching aids for autistic children,and sorting out their action points are conducive to designing more targeted and effective hand-eye coordination rehabilitation teaching aids.The follow-up observation method was adopted for children with autism,and the offline questionnaire survey and user interview method were used for accompanying parents and teachers of rehabilitation institutions.Emotional state in digging into the functional requirements of hand-eye coordination rehabilitation teaching aids for children with autism,and analyzing the design points of hand-eye coordination rehabilitation teaching aids to improve hand-eye coordination rehabilitation functions.According to the specific sensory preferences of autistic children,the reward form of hand-eye coordination rehabilitation teaching aids for autistic children is designed,and visual and auditory rewards are used as strengthening rewards to replace the original food rewards.Combined with Arduino for intelligent module design,the scheme of sensory strengthening reward was realized,and real-time feedback of completing the corresponding tasks for children with autism was realized.Three schemes for hand-eye coordination rehabilitation teaching aids were designed.Two of the aids carried out a 20-day experimental study based on the grass model.The Chen's hand-eye coordination method and can changing experiment were used to test children's hand-eye coordination selection response ability and hand-eye coordination ability.,Conducted pre-test and post-test respectively.The experimental results show that both the teaching aids designed by this institute and the self-made teaching aids of rehabilitation teachers can improve the hand-eye coordination selection reaction ability and hand-eye coordination ability of the children to a certain extent,but the analysis found that the effect of scheme 2 on hand-eye coordination improvement is more obvious.It may be related to the gamification design elements of the plan and the physical collision sound of each step in the operation process.The evaluation of parents and teachers found that plan 2 can improve the social enthusiasm of the children to a certain extent(eye contact,finger indication)And training pleasure(number of smiles,laughs).
