Color combination of information display interface based on Kansei Engineering and paired comparison experiment

Through the color extraction and perceptual semantic extraction of text disply, this paper puts forward the design elements and guidelines of text information display in public environment. Taking the design of information display in railway station as an example, the relationship model between perceptual semantics and color was established. In this study, the preference selection experiment proposed by Thurstone in psychology was combined with LCJ method and SD method of Kansei Engineering, and the Kansei Engineering evaluation of samples in multiple perceptual dimensions was carried out. The perceptual dimensions were reduced by factor analysis, and the evaluation system architecture of information display was obtained. Then, the paired comparison method was used to evaluate samples in two perceptual dimensions of clarity and pleasure, and the color design elements of public area information display was extracted and summarized. The correlation between perceptual image cognition and sample characteristics was established by regression analysis. Finally, we found that the blue background condition has better performance on the whole, while the text color has great differences in different perceptual cognition, which provides reference for the design of information display interface under different perceptual requirements.
