Abstract
Through semi-structured in-depth interviews, this study summarizes children's main requirements in three areas: literacy methods, literacy vehicles, and parent-child interactions. The results of the in-depth interviews were combined with the theoretical research. Fifteen user requirements were extracted and made into a KANO model questionnaire, which identified 13 valuable user requirements for children's literacy toys and prioritized the 13 effective user requirements; the AHP method was introduced to calculate the weights of the effective user requirements and derive the ranking of the requirements; the quality house model was established based on the QFD quality function configuration theory, and the user requirements were transformed into the design elements and the relative importance was calculated; the relative importance was referenced; the relative importance was calculated based on the QFD quality function configuration theory; and the relative importance was referenced to the design elements. Based on the QFD quality function configuration theory, a quality house model is established to transform user requirements into design elements and calculate the relative importance; the design practice of parent-child interactive children's literacy toy is completed with reference to the design elements with high relative importance; a children's literacy app is tested against the children's literacy toys and the children's literacy toys are evaluated in terms of the efficiency of literacy, interest in literacy, and subjective evaluation, so as to validate the feasibility of the design.
