This study addresses the digital divide faced by the elderly and systematically explores the design principles and practical paths of aging-friendly touch interfaces. By integrating human-computer interaction theory, universal design principles, and cognitive psychology, an aging-friendly design framework with four dimensions, namely vision, interaction, function, and emotion, was constructed. The study adopted a mixed method, combining case analysis and user testing, to verify the effectiveness of innovative designs such as dynamic font size adjustment, multimodal feedback, and progressive learning guidance. The study found that successful aging-friendly design not only needs to solve usability issues at the operational level but should also pay attention to the psychological needs and trust building of elderly users. The "capability-centered" design concept and quantitative evaluation tools proposed in the study provide a systematic solution for the aging-friendly transformation of digital products and have important theoretical and practical value for promoting digital inclusion.
