Study On The Interface Of Health-Preserving Apps For The Elderly Population Based On The Emotional Design Theory

China has entered an aging society,How to make the elderly have a healthy body is receiving more and more attention.The number of elderly people using smart phones in the mobile Internet era has increased,Under the background of the Internet and health industry,the elderly health-preserving APP has been born.The current elderly health-preserving APP has a tendency to be younger.The health-preserving APP developed for the elderly doesn't consider the needs of the elderly,and the elderly are separated on the edge of mobile users,making it difficult to enjoy the convenience brought by the Internet.Through related theoretical research,product status analysis and user characteristics analysis,the article finds the emotional design elements of the elderly health-preserving APP,the emotional needs of the elderly for the health-preserving APP.The author proposes the elderly health-preserving APP interface design method based on the emotional design theory.The elderly use the health-preserving APP to have a good operating experience,generate a positive and optimistic attitude,and achieve physical and mental health,The elderly can truly enjoy the convenience brought by technology.The main population of the study is young people aged 60-74.The research object is the elderly group's health-preserving APP.Based on the three-level theory of emotional design,this paper studies the physiological,psychological and emotional characteristics of the elderly,investigates and analyzes the emotional needs of the elderly in the instinct,behavioral and reflective layers of the health-preserving APP,and finds the design method of the elderly community-based APP interface.Post design practice.The theoretical research of the thesis includes emotional summary,three-level theory of emotional design,related overview of health-preserving APP,and analysis of emotional design elements of health-preserving APP.Clarify the target user population,market status and development trend,select three typical elderly group health-preserving APP,and study the emotional design elements of the instinct,behavioral and reflective layers.To study thephysiological,psychological and emotional characteristics of the elderly,and to investigate the emotional needs of the elderly in the instinct and behavioral layers of the health-preserving APP,to investigate the emotional needs of the elderly in the reflective layer of the health-preserving APP,to construct a user role model,and to have three levels of emotional needs.Integration.This paper proposes an elderly group health-preserving APP interface design method based on emotional design theory,including information structure design,interface information layout,visual element design,behavior layer functional definition,interface information understanding design,interface information memory design and interaction design.Principles,the reflective layer creates a sense of novelty,triggers a sense of belonging,stimulates self-experience,and alleviates negative emotions.According to the design method of the elderly group's health-preserving APP interface proposed in the previous period,the APP design practice of “Health increases life expectancy”” was designed to build a health-preserving APP suitable for the elderly,and the user satisfaction test was carried out to verify the feasibility of the method.Therefore,based on the three-level theory of emotional design,this paper proposes an elderly group health-preserving APP interface design method based on emotional design theory,so that the elderly group health-preserving APP can better serve the elderly,help them better care for the body,keep the body and Mental health.
