The work aims todevelop a method to evaluate and optimize the perceptual design of product styling forms, which incorporate both universal and personalized features, so as to assist designers and related businesses in reducing product development expenses and improving design efficiency. The evaluation criteria were derived from internationally renowned design competitions. Various methods, including expert methods and principal component analysis, were used to determine personalized optimization guidelines for specific product styling designs. The evaluation process for the product styling perceptual design, which had strong applicability, was constructed by comprehensively using hierarchical analysis, questionnaire research, and other methods. The constructed evaluation method was then verified. The product styling perceptual design evaluation method, based on personalized evaluation, combines the respective advantages of quantitative analysis and qualitative analysis. It addresses the issue of incompatibility between generalization and differentiation in the current evaluation process. It can not only improve the evaluation efficiency of product styling design, but also offer targeted personalized design optimization suggestions for specific products. Finally, the effectiveness of the evaluation method is verified through evaluating the shape of mouse products, which introduces a new approach to assess the perceptual design of product styling.
