This article employs Principal Component Analysis (PCA) to investigate the perceptual characteristics of Feitian figures in the Yungang Grottoes. It analyzes participants’ ranked preferences for these figures’ perceptual imagery, extracting three pairs of representative characteristics. Building upon this analysis, the article explores design elements and spiritual communication, presenting a jewelry design methodology that concurrently considers the perceptual, representational, and spiritual aspects of Yungang Feitian figures. The study evaluates three design approaches: traditional, hybrid (traditional and AI-assisted), and pure AI-assisted jewelry design. The objective is to innovate design methodologies, summarize new approaches, and skillfully integrate traditional culture with modern design.
