This study aims to explore the relationship between design elements in industrial heritage revitalization and their visual appeal by analyzing users' visual attention and subjective evaluation of contemporary design techniques in the context of heritage. A mixed analysis framework combining quantitative and qualitative methods SBE-SD approach and eye-tracking was employed to investigate modern design languages in the industrial heritage context. Based on the results from questionnaires, rating scales, and eye-tracking experiments, this study identifies the characteristics and differences in visual appeal, user perception, and satisfaction across different architectural types. Industrial heritage revitalization, through methods such as the reproduction of spatial memory, modern expansion, design response, green landscape integration, and sculptural expression, balances historical preservation with innovation, achieving an organic combination of heritage conservation and contemporary needs. This study provides valuable insights for the future transformation and revitalization of industrial heritage.
