Abstract
As the method of research, image words contributed to the attitude of liking the glasses design were calculated by multiply regression analysis, and cognitive parts affected to each image word of the glasses design were extracted by rough sets. Four image words "foppish (fashionable), pretty, decent, intellectual" in twelve contributed to liking were calculated using the data evaluated into five steps about each image word on the subject of twenty women. Next, the relationship between four images and cognitive parts was extracted based on the decision class using the data of each image word. From the result, the hierarchical relation from the attitude to cognitive parts about the preference has been clarified. Furthermore, the verification experiment of the result of the hierarchical relation was conducted on the subject of a designer working a design office, who proposed three design sketches with some useful comments to improve the method.
