ERP-based Automotive Interior Color Perceptual Research And Innovative Design Applications

With the transformation of the automobile development model,major changes have taken place in the automobile market,followed by changes in the age composition of the automobile consumer population,car purchase concepts,and aesthetic experience.The concept of "people-oriented" automotive interior design has become a powerful means for companies to respond to market competition.It requires the design to be centered on user experience and meet user needs.As one of the design factors that have the greatest impact on users' perceptual cognition,color is the focus of current automotive interior design.In traditional interior color design,randomness and errors caused by subjective evaluation are unavoidable.In order to obtain more objective and accurate user perceptual cognitive information,this paper introduces EEG measurement technology,collects and records the physiological data generated by the human brain in the cognitive process,extracts the ERP components that reflect the cognitive characteristics of the human brain,and analyzes the underlying Perceptual cognitive information is used in the evaluation of interior color schemes.First,conduct an in-depth research on the development status of automotive interiors through online platforms,literature,and magazines.Collect interior color pictures and related vocabulary,summarize them to obtain representative images,typical hue and color space layout,and use the combination of hue and space layout to create new interior color samples,so as to carry out EEG-based sensibility Cognitive experiments,recording the EEG data generated by the experiment(the amplitude of the ERP component N400)and behavioral data(reaction time,selection rate).Then the standardized experimental data is used to calculate the relative closeness ranking of different samples under each image through the comprehensive method of entropy weight TOPSIS,which indicates the corresponding relationship between the two.Finally,the relative closeness ranking table is used as a reference for the design to be redesigned,and through the evaluation of the focus group,the design results are in line with the target image,and the research results are also verified for the design reference significance and value.
