Artificial Intelligence-Generated Content (AIGC) is rapidly transforming various industries, including interior design. This research explores the integration of AIGC through qualitative and quantitative methods, notably text analysis based on insights from designer interviews and the Analytic Hierarchy Process (AHP) to evaluate the research results. Findings suggest that AIGC significantly enhances communication, innovation, and decision-making efficiency. However, accuracy, reliability, and human-AI interaction remain significant concerns. The study provides practical implications for designers and highlights pathways for more effective human-centered AI integration, setting foundations for broader digital transformation strategies in creative industries.
