Abstract As China's urban development shifts towards stock renewal, the transformation of community public spaces increasingly prioritizes public participation as the true users. Concurrently, augmented reality technology offers fresh perspectives on traditional participatory design models. This paper explores two main questions: how to integrate new technologies into traditional participatory design and how to develop strategies for renovating old villages. A feasibility assessment of AR participatory methods was conducted through quantitative experiments, alongside empirical research on AR participatory models based on practical evidence. The theoretical research section of this paper primarily uses literature analysis and case studies to examine the foundational theories of participatory design, emphasizing how augmented reality can optimize its components and methods.
