A Study On The Cognitive Evaluation Of Images Of Embroidery And Embroidery Of Ethnic Minority Costumes In Guizhou Based On The Integration Of Eye Movement And EEG Technology

As a visible and tangible design element,embroidery in clothing has a greater impact on consumers’ perceptual experience.However,the current level of content of relevant research is mostly distributed in the field of embroidery colors and patterns.For a single embroidery type-image Cognitive evaluation research has not yet conducted in-depth research,and no corresponding solutions have been proposed for the degree of fit and classification of embroidery species-images.Therefore,in view of the lack of research on the perceptual image of embroidery in the evaluation of traditional apparel experience design,in order to associate and externalize the implicit perceptual image of embroidery with the perceptual needs of users,under the support of the theory of vision and touch,and Kansei Engineering theory,based on The fusion of eye movement and EEG technology to study the cognitive evaluation method of the imagery of Guizhou ethnic minority costume embroidery.First,through the Delphi method and the literature survey method,the embroidery categories of Miao-Dong ethnic costumes in Liping County were collected and initially screened,and 18 embroidery methods were obtained.In order to determine the production process of the embroidery method,the three eye movement indicators of the eye movement technology,the heat map,the continuous gaze time,and the number of gaze points,are used to comprehensively analyze the production process of each embroidery method,so as to invite the embroiderer to make an experimental sample of a single embroidery type.Obtain the representative sample objects of the later tactile cognition experiment,and take photos to obtain the representative sample pictures of the visual cognition experiment.Secondly,this paper proposes a subjective cognitive evaluation method based on the KE-VT method for the embroidery species-image of Miao-Dong ethnic costumes in Liping County,and obtains the subjective cognitive evaluation data of the user’s embroidery species cognition.Based on KE,under the AB-VT evaluation mode,the visual image group and tactile image classification experiments are carried out on the embroidery image group,and the A tactile image group and the B visual image group are established.Through systematic analysis and similarity analysis,the representative image word pairs were extracted respectively,and a total of representative image word pairs were obtained in which A represents the three dimensions of roughness,warm and cold,soft and hard,and B represents the four dimensions of new and old,clumsy,dense,and expensive.Subsequently,based on the PCA method,the eye movement index,the EEG index and the subjective evaluation index were combined to construct the apparel embroidery embroidery species-image cognitive evaluation model.The single-factor analysis of variance was used to screen the indicators,and the PCA method was used to fuse the evaluation indicators to establish a single embroidery species and Image association model,comprehensive evaluation index is obtained,and the model is tested by paired T test.Based on the above-mentioned further,the classification of embroidery speciesimage fit degree of Miao-Dong ethnic costumes in Liping County was researched,so as to obtain the classification of embroidery species-image fit degree.That is,the GAR method is used to calculate the correlation degree between the embroidery speciesimage comprehensive evaluation index and the reference value,and the embroidery species-image composition method is analyzed according to the order,and the classification regression equation is constructed according to the correlation value value and the RSR method to obtain the embroidery species-Image fit degree classification result.Finally,based on the existing single embroidery product as a case,the embroidery species-image cognitive evaluation method was verified,and the embroidery-image classification method was used for practical verification.The results show that the evaluation effect of the visual and tactile methods of embroidery species-imagery matches well with the user’s subjective evaluation model.The experimental results show that the image composition method and visual and tactile image recognition classification of ethnic embroidery species in Liping County are obtained.In order to assist the innovative design of apparel embroidery for user perceptual experience,it provides image selection and reference for ethnic apparel embroidery for perceptual apparel experience design.
