The work aims to explore a method of designing interactive play and teaching aids for children's sensory training that creates an associative experience, so as to scientifically guide the design process of children's play and teaching aids in terms of function and form. Firstly, common design elements of existing children's sensory training play and teaching aids were extracted through interviews and research. A questionnaire based on the user's associative experience and the Kano model was developed to summarize the design needs of the target users, i.e., children aged 3-6 years old. The priority ranking was analyzed. Secondly, a hierarchical analysis model was constructed based on the results of the questionnaire to analyze the design principles, and then the weights of each indicator were calculated based on the judgment results of the expert group to derive its weight value and ranking. Finally a fuzzy comprehensive evaluation was conducted on each indicator of the example research proposal. According to the Kano model and fuzzy hierarchical analysis method (FAHP), several factors that had the greatest influence on the design of interactive play and teaching aids for children's sensory training were finally derived along with the scoring of the design scheme to guide the optimization of the design scheme. By combining the Kano model and the fuzzy hierarchical analysis method (FAHP), the research model is applied to the design of children's sensory training interactive play and teaching aids to make the design scheme more scientific and reasonable, which provides new theoretical methods and ideas for the design research of related children's play and teaching aids products.
