Media art attracts public attention for its newness and differentiation from existing art and media art converged with the latest technology, AI is being presented in public art. This paper proposes interactive media art using AI as public art. Powerful interactions that are more personalized, non-linear, and multidirectional should be delivered through AI. They need to make interactive media art more interesting for citizens to expect and participate in, and provide differentiated experiences through diverse communication and empathy with artworks. When establishing public art policies, a virtuous cycle structure that leads to public participation is proposed by preparing a strategy to promote the work to the public through sharing and co-creation of artworks on SNS. For citizen-centered public art, citizens' needs should be identified through AI data analysis and reflected in policies and creation. Interactive media art using AI as public art should promote citizen participation and communication and advance in the direction of developing a citizen-centered culture.
