Design and Evaluation of an Intelligent Rehabilitation System for Children with Asthma

Establish a demand index system for children’s asthma product service systems to provide theoretical basis and guidance for the design of children’s asthma machines, ensure that the design practice plan meets the basic needs of target users and improve the user experience. The Affinity Diagram (KJ) method was used to screen and organize the needs of target users, and the functional requirements of 26 children’s asthma product service systems were obtained through literature research, user interviews, etc., and the Analytical Hierarchy Process was used to conduct forward and reverse analysis of the obtained functional requirements. In accordance with the questionnaire, the comprehensive weight values are derived, and subsequently, a consistency test is conducted to ascertain the design elements of the product. Combining research conclusions and design practice, a children’s asthma machine product system was designed from the aspects of intelligent software, interesting shape, comfortable use, and visual screen. The system design of children’s asthma products obtained by combining KJ method and AHP method in product design and conducting fuzzy comprehensive evaluation analysis is practical. Through qualitative and quantitative analysis, the real needs of users can be accurately captured, and strategies for applying new theories to solve problems can be summarized more intuitively and effectively.
