Research On User Interface Interaction Design Of Mobile Application Based On User Mental Model

The popularization of smart phones and the innovation of mobile communication technology have driven the rapid growth of various mobile applications(APP)such as entertainment,social networking,and learning.A large number of APP products not only meet people's entertainment and social needs,but also greatly improve people's work efficiency and learning efficiency.In this context,the competitive pressure of APP products is increasing,and the sensory,interactive and emotional experience generated by users when using APP has gradually become the core competitiveness of various APP products.In order to enhance the user experience,it is necessary to further optimize the user interface(UI)design,interactive behavior and mode design,and emotional design in details of APP products.The research first starts from investigating the current situation of UI interaction design of APP products,using questionnaire survey method to investigate and analyze the user preferences and behavior characteristics of APP products and the problems existing in the UI interaction design of APP products.Secondly,using literature research method and content analysis method,discuss the role and significance of mental model,network information behavior,flow experience and other theories in UI interaction design research.Next,using the interdisciplinary research method,based on the theoretical basis of cognitive psychology,the factors that affect the user's mental model are divided into two parts: experience and expectations,and combined with the user's network information behavior and flow experience to construct The mental model of APP users.Then,according to the three levels of the user's mental model,the UI interaction design principles of APP products are proposed.Finally,the proposed design principles are applied to the UI interaction design of the case-"Lemon Photography " APP,and tested and iteratively optimized.The research aims to further improve and develop the theory of mental models so that the theory can be better applied to the UI interaction design of APP products and improve the user experience of APP products.And by constructing a mental model for APP users,it provides guiding suggestions for the interface design and Interaction Design of APP products,and designs and implements a learning APP product with a good user experience.Usability test results show that the theories and methods proposed in this paper have certain feasibility and effectiveness in the UI interaction design of APP.
