  Human-centered AI (HCAI) is a design philosophy that advocates prioritizing
humans in designing, developing, and deploying intelligent systems, aiming to
maximize the benefits of AI to humans and avoid potential adverse impacts.
While HCAI continues to influence, the lack of guidance on methodology in
practice makes its adoption challenging. This paper proposes a comprehensive
HCAI framework based on our previous work with integrated components, including
design goals, design principles, implementation approaches, interdisciplinary
teams, HCAI methods, and HCAI processes. This paper also presents a
"three-layer" approach to facilitate the implementation of the framework. We
believe this systematic and executable framework can overcome the weaknesses in
current HCAI frameworks and the challenges currently faced in practice, putting
it into action to enable HCAI further.
