In the context of the era of big data, this study explores how big data affects the innovative trends and future prospects of art design. Through integrated application of data collection, processing, model construction and validation, as well as trend prediction and analysis methods, this study reveals the application value and potential of big data technology in the field of art design. The study found that big data not only provides rich resources and inspiration for design but also promotes the improvement of design efficiency and innovation through data-driven decision support. At the same time, the predictive analysis pointed out that the future of art design will be more focused on digital, user experience, sustainability, and interdisciplinary collaboration. Despite the technical challenges of data processing and the ethical issues of user privacy protection, these challenges can be effectively addressed through education and training, interdisciplinary cooperation and policy support to open up new directions for art design. This study provides a new perspective and practical strategy for the integration of art design and big data, and has important theoretical and practical significance for designers, educators and policy makers.
