Abstract: According to the principle of Kansei engineering,the perception of woman′s overcoats was researched.The space of designing elements and the space of perception were established respectively.The semantic differential method was applied to questionnaires.The numerical designing elements,which were obtained by the quantification theory,and the average value calculated from the data of questionnaires were put into multiple linear regression.The results of the regression were analyzed.The relationship between the two spaces was quantified,and mathematic models were established.These models can be applied to predict the perception evaluation of woman′s overcoats.
