Research On Application Design Of Medical And Health Care For Middle-aged And Elderly People From The Perspective Of User Experience

The development of interaction design makes the focus of design shift from product to human,and design emphasizes user experience more.With the deepening of social aging,while middle-aged and elderly people are gradually accepting Internet medical services,there is still much room for improvement in the aging-appropriate transformation of corresponding medical and health APPs.This paper takes this as a starting point to study the user experience of medical and health APPs for middle-aged and elderly people.It is intended to propose a design model that can help middle-aged and elderly people improve the user experience of medical and health APPs.Based on the medical and health user experience of middle-aged and elderly people,this paper firstly sorts out the more important user experience theories and evaluation models in the field.The design model has three dimensions:perception layer,behavior layer and value layer.Then collect user experience cases through in-depth interviews,observation and other research methods,and extract the influencing factors of user experience through the sorting and analysis of the interview records.evaluation criteria in one dimension.The evaluation criteria of the perception layer are attractiveness,desirability,and findability,and the evaluation criteria of the behavior layer are functionality,effectiveness,and ease of use.The evaluation criteria of the value layer are caring,trust,and positivity.They are relatively independent,but also related to each other and influence each other,resulting in the overall feeling of the middle-aged and elderly people on the product.This paper further proposes strategies and methods to optimize the user experience of medical and health APPs for middle-aged and elderly people,including visual design that is beautiful,visual hierarchy that uses less to be more,visual recognition that replaces complex with simple,efficient information acquisition,and highly simplified interaction.Steps,high-enhanced interactive feedback,deep care,enhanced trust,transmission of positive energy,etc.At the same time,these design strategies are used in design practice.
