为了提升智能吉他的使用体验,降低吉他学习门槛,构建青少年用户心智模型,探索青少年用户在吉他学习过程中的实际需求,以期设计出更加符合青少年用户需求的智能吉他,推动乐器智能化的运用与普及。采用POEMS观察框架,对青少年用户的吉他学习行为进行观察和记录;收集包括人物、物体、环境、信息、服务等方面的内容,从中提取操作任务、情感变化、使用痛点等相关的信息,构建青少年用户心智模型寻找机会点;再运用填充、合并的设计方法,从设计师的角度出发提出设计策略,以指导设计实践。完成了青少年用户学习吉他的心智模型并提出形变设计、辅助练习设计、功能集成设计三个部分策略进行设计实践。通过深入洞察用户心智模型,以精准把握青少年用户学习吉他时的心智空缺,有针对性地提出设计策略,提升吉他的用户体验和学习效率,为乐器的智能化提供了新的研究路径。

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.
