Research on Users' Satisfaction of App Interface of Mobile Phone Business Hall Based on Kano Model and Eye Movement Tracking

Researches on user satisfaction are of great significance to product improvement and user experience enhancement. Using eye trackers as research aids can make up for the low objectivity of the traditional usability testing. The purpose of this study is to evaluate the user satisfaction of the App interface of two mobile phone business halls based on the Kano model theory and eye movement tracking methods, and explore ways to improve the user satisfaction of the interface. In this research, 15 subjects are invited to use two Apps to complete the same tasks and eye trackers are used to record fixation counts and duration. Besides, the Kano model questionnaire is applied to divide the level of functions on task pages. Subjective and objective measurements show that the interface design of Unicom App is more consistent with the results of the two-dimensional questionnaire of Kano model and "F" vision model, and its user satisfaction is also higher.
