Enhancing the Double Diamond: Human-AI Co-Creation in UI Design through AIGC Integration

The rapid development of artificial intelligence generated content (AIGC) technologies (such as ChatGPT, Midjourney, and Sora) has profoundly changed design practice by facilitating creativity and efficiency. As a structured design framework, the Double Diamond still plays an important role in the design process. As AI technologies continue to develop, the Double Diamond can integrate the AI technology to better meet the needs of the current design process. This paper proposes an innovative AIGC-enhanced Double Diamond that integrates AI tools (such as ChatGPT for idea generation, Midjourney/Sora for visualization, Wix ADI/Photoshop/Illustrator for prototyping, and Figma for delivery) with traditional and emerging design tools. We used a mental health application as a hypothetical scenario to assess the feasibility, flexibility, and inclusiveness of the framework in the four stages of Discover, Define, Develop, and Delivery. This paper aims to contribute to design theory and practice by extending the research of the Double Diamond framework and providing practical insights for human-IA collaboration design in UI design.
