Design Of Gestural Interaction Product For Autistic Children Hand Training Based On Flow Theory

The development of hand movement skills in children with autism has a direct impact on their life,so rehabilitation training for their hands is extremely important.With the continuous development of science and technology,somatosensory games are gradually applied to the rehabilitation training field of autistic children,but most of the previous studies are from the perspective of technology,often neglecting the user experience of the product,greatly reducing user satisfaction and viscosity,and can not achieve the effect of rehabilitation training well.Therefore,the research focuses most on how to improve the user experience of autistic children,stimulate their intrinsic motivation of training,enhance the initiative of training and the effect of training.This research includes the interactive design of somatosensory games and the design research of training aids.Based on flow theory,we researched trough questionnaire survey,field observation and in-depth interview,Analyzed through the interactive experience of autistic children’s game training and the factors of positive experience are integrated.Then we got the elements of immersive experience of autistic children in game training are determined by data collection,collation and analysis.Based on this,the design of somatosensory games and training aids are put forward respectively.Analytic hierarchy process method(AHP)was used to establish a hierarchical analysis model of somatosensory game design with timely and moderate feedback,pleasant interface performance,effective operational interaction,clear target task four somatosensory game interaction design strategy,and three training aids design strategies with safe operation process,comfortable operation experience and affinity.Combined with the characteristics of autistic children and the questions encountered during the current training process problems and requirements,output a series of design schemes,and finally use the technique for order preference by similarity to an ideal solution method(TOPSIS)to choose the design scheme and carry out in-depth design.The flow theory,AHP method and TOPSIS method are applied to the design of hand somatosensory interactive training products for autistic children,and the process of product design and evaluation based on this method is created.The feasibility of the study is demonstrated through design practice,and the user experience of autistic children in rehabilitation training using somatosensory games is improved.And it provides some experience and reference for product design and development in autism related fields in the future.
