App Design Of Drug Purchasing For The Elderly Based On Behavioral Design

In the context of the rapid development of mobile Internet,mobile phone reservation,intelligent drug sales and drug delivery services have brought many conveniences to life.China's aging population has further deepened,and the number of elderly users has gradually increased.Due to the decline of physical function and cognitive ability,there are a series of problems in the use of the elderly,but there is no drug purchase app specifically for the elderly.Therefore,this paper is feasible and practical in terms of social background and practical needs.Starting from the discussion of the existing apps for the elderly and drug purchase apps,this paper summarizes the problems and challenges faced by the elderly,deeply studies the research tools of behavior design-Fogg behavior model,analyzes the relationship between the three elements of Fogg behavior model: motivation,ability,contact and triggering user behavior,determines the design principles of drug purchase apps for the elderly,and defines the feasibility and importance of behavior design in app aging design,It also puts forward specific design methods to provide reference and guidance for the design of drug purchase app for the elderly.This paper launched the design practice,through questionnaire survey and in-depth interview,deeply analyzed the use needs of elderly users,extracted the specific use pain points of the elderly,applied the design principles and design methods of the elderly drug purchase app to the design practice,and designed the information architecture,visual elements and interaction mode suitable for the elderly drug purchase app.Through the results of design practice,an attempt is made on the aging design of drug app for the elderly,which provides a certain reference for the design of the same type of APP in theory and practice.
