Design And Evaluation Of Aging Adaptive Interactive Components For Smartphone Applications

With the development of modernization and urbanization,population aging has gradually become a difficult problem in front of China and the world.How to further facilitate the life of the elderly,stimulate the production and consumption ability of the elderly,and enable the elderly to better adapt to the information age,age-appropriate design has become a popular design trend nowadays.Especially in the design and development of Internet information technology products,the country has issued a series of guidelines and specifications for age-appropriate design in recent years.Many applications,especially mobile apps,have also opened the design of aging-friendly mode,but it is still in the initial stage.Enterprises often complete the aging-friendly design by simply enlarging the font and reducing the functions on the basis of the original App,and the experience is relatively poor.By using atomized interaction components,designers nowadays can quickly build perfect interaction prototypes and front-end pages,and ensure the design consistency of product matrix.However,there is little research in the field of agingfriendly interaction components.This study explores and designs a set of aging-friendly mobile Internet programs in the new era with new design ideas and concepts based on the guidelines of the Ministry of Industry and Information Technology’s General Design Specification for Aging-Friendly Mobile Internet Applications(APP)by studying the perception,cognition and psychological state characteristics of the elderly and starting from their interaction experience.This paper starts from the achievements and shortcomings of the existing domestic and foreign ageing-friendly design,analyzes the physiological and psychological characteristics of the elderly group,and analyzes the user needs of the elderly group by means of field research and user interviews.Through human factors engineering experiments and atomized design ideas,a more detailed aging-friendly design specification is produced,and a set of aging-friendly design components focusing on the elderly is attempted to be built.The components include layout and navigation,color themes,icons and buttons,text and forms,and so on.The usability test shows that the results of this project can solve most of the difficulties encountered by the elderly in using smart devices,and provide some value to the design development of aging-friendly interactive components.
