Abstract
Based on sensory integration training, D-S theory and extenics, this paper discusses the innovation and development of ADHD children’s toys, so as to make the design scheme more real, scientific, and comprehensive and meet the internal needs of users. Considering the advantages of extenics and the D-S theory in dealing with uncertain and incompatible decision-making problems, an evaluation method of toy design scheme for special children based on extension analysis and the D-S theory is proposed. Through the combination of the D-S theory and extenics evaluation method and sensory integration training theory, the designed toy scheme has a certain auxiliary therapeutic effect on the rehabilitation of ADHD children. Through the design case of physical fitness for ADHD children, it is proved that the combination of the D-S theory and extenics based on the sensory integration training theory has a certain reference value for the generation of product scheme and makes the product design process more comprehensive and objective.

When the correlation function is greater than 0, it indicates that the element has a certain property, and the larger the value is, the closer it is to the property; when the correlation function is less than 0, it means that the element does not have this property, and the smaller the value, the farther away from this property; when the correlation function is equal to 0, it indicates that the element may or may not have this property, which is a critical element. erefore, the correlation function can be extended to the basic probability assignment (BPA) function in the D-S theory, that is, the larger the correlation function is, the larger the value of BPA converted is, on the contrary, the smaller the value of BPA converted
The treatment of Attention deficit hyperactivity disorder (ADHD) children is mainly behavioral intervention, and its repeatability and drug side effects lead to poor treatment effect. e physical training method of sensory integration has the advantages of safety, simplicity, and low cost, which is accepted and welcomed by many parents
Summary
With the progress of bioengineering, medical technology, electronic equipment, and other industries, more and more diseases have been found and paid attention to. Attention deficit hyperactivity disorder (ADHD) is one of the most common mental diseases in children [1,2,3,4]. According to domestic media reports, the incidence rate of ADHD in childhood is 2.59%∼7.25%. Children with ADHD have lower basic abilities than normal children, such as learning ability, executive ability, activity ability, and social communication ability. Childhood is the main period of people’s learning. If they are not treated in time, it will affect their adulthood and even their whole life [5, 6]
