A Basic Study of Method Dealing with Non-Linearity of Kansei

感性工学是由广岛大学的长町光夫教授在大约30年前创立的，它已经在日本和世界范围内蔓延开来。它被定义为“一种将消费者对即将到来的产品的感觉和形象（感性）转化到设计领域的技术”。由于消费者的感性体现在产品的设计和功能中，通过感性工程开发的新产品销售很好，有时甚至在市场上形成了新的弯道。目前，感性工程已广泛应用于汽车、工程机械、家电、房屋建筑、服装、化妆品等行业。据说感性一般具有非线性的特征。然而，我们在统计分析方面把它作为线性处理。本研究的重点是明确感性是线性的还是非线性的，并建立一种能够加热感性线性特性的方法。为此目的进行的实验表明，感性线性依赖于感性词本身。例如，“大-小”、“重-轻”、“简单-复杂”等与身体特征相关的感性词汇在评估数据中表现出线性关系。而那些与审美有关的词语，如“美-丑”、“美-不美”等，则导致了非线性特征。我们从因子分析、量化理论和非线性回归分析中发现了这些有趣的结果。

Kansei Engineering was founded by Professor Mitsuo Nagamachi at Hiroshima University about 30 years ago and it has spread out in Japan as well as in the world. It is defined as "a translating technology of consumers' feeling and image (Kansei) on a coming product into the design domain". Since the consumers' kansei is implemented in the product design and its function, the new products developed through the kansei engineering have sold very well and sometime it constructed the new bend in the market. The kansei engineering has been introduced so far in industries of Automobile, Construction Machine, Electric Home Appliance, House Construction, Costume, Cosmetics and so forth.It is said that the kansei has in general the non-linear characteristics. However, we have dealt with it as linearity for treatment in terms of statistical analysis. The concern of the present research is to make clear whether the kansei has linearity or non-linearity and to construct the method, which is able to heat the linear characteristics of kansei. The experiments conducted for this purpose showed that the kansei linearity relies on the kansei words themselves. For instance, the kansei words related to the physical trait like "large-small", "heavy-light", "simple-complicated" and so on showed the linearity in the evaluated data. But those words concerned with aesthetic like "beautiful-ugly", "graceful-not graceful" and the like resulted in the non-linear feature. We found out these interesting results in terms of Factor Analysis, Quantification Theory and non-linear regression analysis.
