This study aimed to quantify the relationship between prosthetic users' emotional response to prosthesis aesthetics and specific product properties. Words representing prosthesis users' emotional response (Kansei) to different aesthetic designs of prostheses were identified via interviews and mood boards. A group of experts consolidated the words into thematic groups, each represented by a single, high-level 'Kansei' word. 53 lower limb prosthesis users completed a questionnaire, rating their perception of 13 aesthetic designs using the 'Kansei' words. Quantification Theory Type 1 was applied to explore the relationship between words and product properties. Sub-analyses assessed for differences based on sex, age and level of extroversion. 5 high-level Kansei words were identified ('Natural', 'Technological', 'Cool', 'Unique' and 'Functional'). The Kansei word 'Natural' had a strong association with realistic looking prostheses while the words 'Technological', 'Cool' and 'Unique' were strongly associated with expressive designs which incorporate hard, colourful covers. The word 'Functional' was not a reliable predictor of product properties. No major differences were observed within sub-grouped categories. Kansei words identified in this study can be used to help guide clients in their aesthetic design choices and to assist designers in achieving the desired response from their products.
本研究旨在量化假肢使用者对假肢美学的情感反应与特定产品属性之间的关系。通过访谈和情绪板确定了代表假肢使用者对不同美学设计的情感反应（感性）的词汇。一组专家将这些词汇整合为主题组，每个主题组由一个单一的、高层次的“感性”词汇代表。53名下肢假肢使用者完成了一份问卷，使用这些“感性”词汇对他们对13种美学设计的感知进行评分。应用量化理论类型1来探索词汇与产品属性之间的关系。子分析评估了基于性别、年龄和外向程度的差异。确定了5个高层次的感性词汇（“自然”、“科技感”、“酷”、“独特”和“功能性”）。“自然”这个感性词汇与外观逼真的假肢有很强的关联，而“科技感”、“酷”和“独特”这些词汇与采用坚硬、色彩丰富外壳的富有表现力的设计有很强的关联。“功能性”这个词汇并不是产品属性的可靠预测指标。在分组类别中未观察到重大差异。本研究中确定的感性词汇可用于帮助指导客户进行美学设计选择，并协助设计师实现其产品所需的反应。
