Abstract
In general, in order to develop a new product, “traditional marketing research”is based on statistics methods in kansei engineering which usually needs massive data and takes lots of time. In this paper, we discuss a new method of marketing research to collect the best design profits by using less data. A new automatic measurement system of kansei information was presented, and three processes of analysis based on grey theory were proposed. First of all, we analyzed the relationship of key images about products. Next comes a method which analyzes all the features of each product. Third, we analyzed the products to fit for the consumer needs. Thus, we were able to achieve the greater investigation results with less data. As an example, the optimal result about a marketing research of dustbin was shown.
