| 摘要: |
| 目的 以医用护栏的仿生设计为例， 进行用户对仿生产品的感性认知尺度的研究。方法 建立了用户对仿生产品感性认知的约束模型， 使用语义差分法量化用户对仿生原型和不同程度仿生方案的感性意象认知， 得到意象形容词之间的关系， 并提出了用余弦相似度作为衡量意象距离的尺度。结论 测量了用户对仿生原型和不同程度仿生方案的认知差异， 还得到了用户对仿生程度不同的产品的喜爱度， 从而得出最适度的仿生方案， 最后设计出与用户感性认知最匹配的仿生产品， 帮助设计师以适度的仿生满足用户需求。 |

| Abstract: |
| Taking medical guardrail bionic design as example，it researches users′perceptual cognition scale to bionic products. It establishes users′perceptual cognition constraint model on bionic products.It uses semantic differential method to quantify users′ perceptual image cognition for bionic prototype and bionic solutions of different degrees， to get the relationship among the image adjective， and put forward the using of cosine similarity as the measure of image distance.On one hand it measures users′cognitive differences on the bionic prototype and bionic solutions of different degrees， on the other hand we get users′likeability on bionic solutions of different degrees， thus it obtains the optimum bionic solution. Finally it deepens and gets the bionic products which best matches users′ perceptual cognition.This method will help designers to satisfy users′need by moderate bionic designs. |
