中文摘要：

从工业设计出发,提出基于群体文化学的方法来研究产品设计中用户和设计师的隐性知识表达。探讨群体文化学的基本概念及其与产品设计之间的关系,以便携式娱乐终端产品造型为例,结合语义差异、意象尺度和结合分析等研究方法,分析用户和设计师对已有产品的隐性知识的获取及表达形式,建立了便携式娱乐终端产品造型的二维隐性知识表达空间,提出用户和设计师的隐性知识表达模型。研究表明：用户和设计师对便携式娱乐终端产品造型在偏好、感知意象和意象形容词对的理解上都存在着许多差异,在产品设计时,有必要以用户为中心,研究用户的隐性知识,找出其共性和个性特征。

英文摘要：

From industrial design,an approach of ethnography is proposed to study users＇ and designers＇ patterns of tacit knowledge in product design.The concepts of ethnography are introduced and the relation between ethnography and product design is explored. Taken the existed portable media center form design as an example,semantic differential,image scale and conjoint analysis etc are employed to investigate the acquiring and representing of users＇ and designers＇ tacit knowledge.The two-dimensional perceptual image spaces of the portable media center form are established,and the tacit knowledge patterns are presented.The results show that many differences exist between users＇ and designers＇ tacit knowledge representation of the same objects and their interpretations of the same image-words,and it is necessary to adopt user-centered method to study users＇ tacit knowledge and find out the common- ness and individualities during the product design process.
