目的 针对糖尿病患者病足的预防及护理，从患者情绪介入，量化用户体验过程中的情绪水平，结合生理、心理、行为等层面，探究情绪与产品交互设计的关系，提出基于情绪引导行为交互下的产品创新设计策略，并通过“WEICHU”糖尿病足预防及治疗产品设计，进行可靠性实证。方法 围绕用户调研、情绪信息挖掘、数据处理和分析，结合用户体验地图研究方法，以“情感环”等相关理论为基础，采用SAM情绪量表，让被试者进行自我情绪评估，对体验地图中的情绪水平进行量化，深度挖掘用户在患病过程中的情绪体验，以此获得更可靠、准确的设计机会点，优化用户体验地图交互模型，并从用户行为方面探究情绪引导与产品设计的关系，据此搭建糖尿病足预防和治疗产品的功能模型。结论 将患者情绪的成因和变化、体验过程中的情绪水平量化分析作为产品交互设计的考量依据，有利于构建良性交互关系，有效改善糖尿病足患者预防和治疗体验。

In view of the diabetic foot for disease prevention and nursing, the relationship between emotion and product interaction design is explored, from the perspective of emotion intervention, by quantifying the user experience the emotional level combining with physical, psychological and behavior levels. A strategy of product innovation design based on emotion guided behavior interaction is proposed, and the reliability demonstration is carried out through the "WEICHU" prevention and treatment product design of diabetic foot. Focusing on user research, emotional information mining, data processing and analysis, combined with map of user experience research methods, based on the "emotional ring" and other relevant theories, SAM emotional scale was adopted to allow the subjects to evaluate their own emotions, quantify the emotional level in the experience map, and deeply mine the user emotional experiences in the disease process, to gain more reliable and accurate design opportunities, to optimize the user experience map interaction model, and from the aspects of user behavior to explore the emotional guidance and the relationship between product design, on the basis of structures, prevention and treatment diabetic foot function model of the product. The quantitative analysis of the causes and changes of patients' emotions and the emotional level in the experience process as the basis for the consideration of product interaction design is conducive to the construction of a benign interactive relationship and the effective improvement of the prevention and treatment experience of diabetic foot patients.
