With the continuous development of economy and society, people’s demand level is gradually improving, users not only pay attention to the material comfort the products bring, but also pay more on mental feelings when interacting with them. User experience is user participation activities, it will stimulate the emotional response, and form perception and ultimately affect consumer behavior. This study puts forward the methods to evaluate the product according to smart phone based on fuzzy theory, by setting up the evaluation system, establishing the quantized values of user experience and the fuzzy comprehensive modeling to obtain the ranking of the samples.Through interviews among smart-phone users which are based on test website of mobile phone and graphic data and regard the level of emotional experience and the consumers’ behavior models as the theoretical basis, we have a study on elements that affect smart-phone users’ experience. Extracting and analyzing the appearance, operating and feeling key factors of users’ experience, classifying factors into the evaluation index of users’ experience, and then establish an evaluation system smart-phone users’ experience. What’s more, the establishment of the evaluation system provides a framework of indexes’ quantifying and fuzzy modeling.By using three dimensions including the appearance perception, operating availability and comprehensive satisfaction as the measurements of the degree of users’ experience; by designing the experiment plan, collecting and processing the experiment data to quantify the indexes, including adopting the eye tracking method; by setting measure index, quantifying appearance attraction sub index; by adopting the performance measurement method; by setting the test task, sub-indexes of quantitative measure learn-ability and usability; by using self-report measures; by setting the sub-indexes such as the comfortable degree and satisfactory degree of self-report questionnaire and so on, thus the perceptual subject would be quantified as rational evaluation data result, providing quantitative data for fuzzy modeling.Based on the fuzzy theory, establishing fuzzy analytic structure of samples, constructing membership function in terms of the quantitative results of the indexes, and determining its membership degree in fuzzy evaluation set. Through determining sub weights of indexes by expert judgment, setting up the weights of experts the clustering analysis method, the ultimate weights of indexes are determined. The judgment matrix of the first grade index membership degree is set up through the overlay of membership degree. Through the blur processing, the ultimate user experience score and ranking are concluded. The results demonstrate that the method can be used as the evaluation method of the experience of smart phone users.
