This paper analyzes the integration process of the Kano model and the QFD model, combines the advantages of the two, and proposes a method of obtaining the importance of user requirements based on the integration method of the QFD and Kano model. Organize older people’s smart tourism needs and use the Kano model analysis method to categorize each demand attribute. Obtain the self-scoring importance degree of the elderly demand, calculate the satisfaction index of the elderly demand, and get the comprehensive ranking of the importance degree centered on the elderly demand according to the SII, DDI, T_i, and K values of the demand elements. Clarify the elements of smart tourism APP interface design services, establish the relationship matrix between the needs of older people and the service index, and build the service quality house of smart tourism APP interface design for the elderly. Use the smart tourism APP functional interface planning strategy to present the functional design of the APP interface. It can be found that those with higher importance ratings are mainly basic functional requirements, attraction guides, and personalization center, of which the four importance indexes of U6 personalization center are U61=4.72, U62=4.75, U63=4.16, and U64=4.23. The calculation results of the quality house show that the importance of the service elements of the interface design of the APP for senior citizens’ smart tourism is ranked as APP content professionalism, service attitude, recommendation rationality, and service quality. Degree > service attitude > recommendation rationality > after-sale reliability.
