Research On The Aging-friendly Design Of Mobile APP Interactive Interface Based On Kano Mode

Kano model(also known as: Kano model)is a model for identifying user satisfaction with feature acceptance.The model is generally not used to measure user satisfaction directly,but is often used for qualitative analysis.As a requirement analysis method,it has been widely quoted in the design of mobile APP interaction interface in recent years.As the aging continues to deepen and the number of elderly Internet users continues to grow,user experience is increasingly becoming the core competitiveness of the mobile software market.However,the mobile APP interactive interface lacks consideration for the elderly users,and the current interactive interface design method is increasingly unable to meet the needs of the elderly groups.Based on this background,Kano model is introduced and combined with other requirement analysis methods to study the needs of elderly users,aiming to optimize the requirement analysis method based on Kano model,and then serve the mobile APP interaction interface age-appropriate design research.First of all,this paper takes the position of elderly users,aims to meet the needs of elderly users,uses the Kano model and mobile APP interaction interface aging-related theories and the current situation at home and abroad to research and analyze,and clarifies the characteristics,interaction behavior and experience needs of elderly users.Then,this paper proposes the design method and strategy of mobile APP interaction interface.In the initial stage,user requirements are obtained using observation method,user interview and questionnaire survey,and user portrait is constructed according to the preliminary obtained requirements.After that,the information of elderly users is obtained through questionnaire research and combined with Likert Scale plus total scale scoring.Then,the requirements are classified into functional attributes by Kano model questionnaire data combined with the calculation results of the satisfaction index of elderly users and the four quadrants rule,and all functional items are weighted by the method of fuzzy semantic transformation after bandit class;meanwhile,the five-layer model of user experience is introduced to propose the design strategy of the ageing-friendly design hierarchy of mobile APP interaction interface.Finally,this paper carries out the design practice of the aging-friendly project,and adopts the aging-friendly design method and strategy for mobile APP interaction interface to design the aging-friendly interaction interface of "Red Pine" APP.Finally,the feasibility and guiding significance of this design method and strategy are verified by evaluating the design scheme.The innovation of this paper lies in the comprehensive application of Kano model,user profile,demand satisfaction calculation and four quadrant rule,and the combination of five layers of user experience model to propose the design strategy of aging.The significance of this paper is threefold: firstly,it provides theoretical guidance on design methods to meet user needs and improve user experience;secondly,it provides methods and strategies for mobile APP interaction to be age-appropriate design;thirdly,it solves the "digital divide" between the elderly and mobile media to a certain extent.
