Research On Interactive Design Of Information Mobile Application For The Elderly Based On Goal-directed Design

The number of elderly netizens in China is increasing day by day.Access to information is one of the main purposes of the elderly using mobile phones to access the Internet.At present,there is no information mobile application designed for elderly users.This article firstly applies goal-oriented theory to the design interactive design of information mobile application for the elderly and researches the needs and goals of elderly users using information mobile applications and summarizes the principles of interaction design.Firstly,through literature research,I determine the goal-oriented design method and the design principles of mobile phone application for elderly users,and then understand the current market through competitive product analysis.Through user interviews and observations,I record qualitative data from time to time in detail the interaction between different types of elderly users and information mobile phone applications.And I find out important behavior patterns and user goals from it.From these data and behavior patterns,I establish some character models corresponding to the main user types.And then I use the character models as the protagonist to analyze the scene and scenario,from which specific design requirements for the subsequent detailed Design provides guidance were extracted.At the same time,based on the above research,combined with the principles of interaction design for the elders,the interaction design principles of the elderly information mobile phone applications are summarized:close to life,flat and consistent,safe and reliable,and rich companionship,trying to be reference and guidance for similar to the elderly user product design.This article also expands the design practice based on the conclusion of the design research.Through the analysis of the design requirements,based on the goals and pain points of the character model,under the guidance of the interactive design principles of the elderly mobile phone application and the elderly information mobile phone application,the design The interactive framework and visual interface of the "Elderly Information Treasure" mobile phone application have been introduced,and the design has been enriched and improved through scene analysis based on the character model.
