Abstract: In order to increase user’s satisfaction with the interactive guidance system and help designers to accurately obtain users’ needs, the structural equation model (SEM) is introduced into the interactive guidance system, and the elements of user experience of the interactive public guidance system are divided into four latent variables. Then, through expert interview, the observable variables affecting the user experience (UE) satisfaction of each of the four latent variables are analyzed and the SEM questionnaire is established. Next, through questionnaire survey and data analysis, the SEM of the user satisfaction of the interactive public guidance system is established. And the impact weights of the four latent variables and their observable variables are obtained. Finally, taking the campus interactive public guidance system as an example, the function, shape and user interface are improved to improve the UE based on the above user satisfaction SEM. This method is compared, with the assistance of PSSUQ, with the existing interactive public guidance system to verify the feasibility of the design and then provide theoretical implications for further research on the experience design of the interactive public guidance system.
