Research On User Experience Evaluation Of Fitness Mobile Application

With the rapid development of mobile Internet and mobile applications,as well as the implementation of the National Fitness Program,fitness mobile applications have a huge market and broad prospects for development.In the development and iteration of fitness mobile apps,it is recognized that a good user experience will be the key to increasing competitiveness and user stickiness.The paper takes qualitative and quantitative analysis methods with the user research data,and extract the user experience evaluation factors based on user emotion experience model.A user experience evaluation method based on triangular fuzzy AHP is proposed.And make the application of the user experience evaluation method and the improvement design to the fitness mobile app Keep.Firstly,based on the analysis of the classification and characteristics of fitness apps and user research results,the user experience evaluation factors based on the user emotion experience model are extracted.It is divided into visceral layer,behavioral layer and reflective layer,and the 16 user experience evaluation factors are summarized and analyzed from this three layers.And the visceral layer includes color style,layout,dynamic effect,sound effect;the behavioral layer includes content quality,functional quality,ease of use,feedback,gamification,motivation,social interaction and personalization;reflection layer includes brand image,sense of accomplishment,sense of security,surprise.The use of fuzzy comprehensive evaluation of the extracted factors proves that the proposed evaluation factors are valid and can affect the user experience.Secondly,the method of user experience evaluation based on triangular fuzzy AHP is proposed.Based on this method with fuzziness and closer to cognition,the hierarchical structure of user experience evaluation factors was constructed,the weight coefficients of each factor were determined,and the user experience evaluation criteria and comprehensive evaluation calculation method were proposed.Finally,taking fitness app Keep as a case study,we use the fitness mobile apps user experience evaluation method to conduct a comprehensive evaluation and improve the design.After making a comprehensive user experience evaluation of Keep and analyzing each evaluation factor,the improved design is conducted.And the result of the user experience test is obtained through the testing and in-depth interviews.The result also verifies that the user experience evaluation method of fitness mobile apps has some validity and scientificity.
