The work aims to construct a mental model of adolescent users and explore the actual needs of adolescent users in the process of guitar learning, with a view to designing intelligent guitars that are more in line with the needs of adolescent users and promoting the use and popularization of intelligent musical instruments in the quality education of music. The POEMS observation framework is adopted to observe and record the guitar learning behaviors of adolescents and collect contents including characters, objects, environment, information, and services, from which information related to operational tasks, emotional changes, and pain points of use is extracted, an adolescent users' mental model is constructed to find points of opportunity, and then the design method of filling and merging is used to propose a design strategy from the designer's point of view, in order to guide design practice. A mental model of adolescent users learning guitar is completed and a three-part strategy of shape-shifting design, assisted practice design, and functional integration design is proposed for design practice. This study accurately grasps the mental vacancies of adolescents in learning guitar through in-depth understanding of the user's mental model, and puts forward targeted design strategies to enhance the user experience and learning efficiency of the guitar, which provides a new perspective for the design of intelligent musical instruments, and also offers a reference for the intelligent design of other educational products.
