Design And Research Of Intelligent Bicycle For Children With Visual Impairment In Blind School

According to the World Health Organization,the total number of blind people in China is8.248 million,and the number of people with low vision is 67.274 million.The causes of blindness include angular wear disease,glaucoma and trauma.According to the World Health Organization,the total number of blind people in China is 8.248 million,and the number of people with low vision is 67.274 million.The causes of blindness include angular wear disease,glaucoma and trauma.According to a national sampling survey on visual disability of children aged 0 to 6years,it was found that visual disability accounted for 1.1% of the total prevalence rate,of which30% were total blind children and 70% were children with visual impairment with light perception.The daily life of visually impaired children is mainly dependent on the Internet,and like ordinary children,they also have the need for outdoor sports entertainment.With the development of modern science and technology,children with visual impairment can perform all kinds of actions and behaviors like ordinary children with the aid of specific equipment.There are few and expensive products that can meet the outdoor entertainment of visually impaired children and cannot meet the needs of visually impaired children.Based on the above problems,it is proposed to design an intelligent bicycle for visually impaired children to help them realize thinking and physical training.In this paper,an intelligent bicycle with humanistic care is designed for visually impaired children.Based on the psychological needs of visually impaired children,it combines humanistic care with information,intelligence,new technology and other means to meet the outdoor activities of visually impaired children.Intelligent bicycle can reduce the psychological and physiological gap between visually impaired children and ordinary children,and bring psychological comfort and help to visually impaired children.At the same time,due to the lack of market for this kind of products,will produce a lot of economic value.This article adopts the methods of field investigation,literature review and induction analysis,interdisciplinary research,experimental test,theoretical summary and model making to understand the physiological characteristics and psychological needs of visually impaired children,relying on the latest achievements of this research both at home and abroad.The deep integration of ergonomics,design aesthetics and intelligent information technology is deeply studied.The intelligent bicycle model for visually impaired children is made by means of experimental demonstration and theoretical summary.Based on the analysis and research on the psychological and physiological characteristics of4-7-year-old visually impaired children,ultrasonic and audio technology are integrated into thedesign of intelligent bicycles so that the bicycle can automatically identify obstacles and hazards within the set range.And prompt the user with voice.At the same time,in order to satisfy the music preference of visually impaired children,the music module is added to enhance the entertainment function of intelligent bicycles for visually impaired children.In the modeling design,the simple line is used as the body structure,the front wheel drive is adopted,and the auxiliary wheel is added to the rear wheel.To ensure its safety,bicycle tires for full tire design.In view of the insensitivity of children with visual impairment to pattern patterns,the color design has chosen the bright and lively,complete and large area color blocks suitable for the children with visual impairment.
