Human-Centered AI: Advancing Research and Applications in Human-AI Interaction Advancing Research and Applications in Human-AI Interaction

Dr. Wei Xu is Chief Scientist at HCAI Labs in California, USA, and an Adjunct Professor. He previously worked as a Senior Research Scientist and served as Principal Engineer in Human Factors and Human-Computer Interaction (HCI) at Intel (USA), where he also chaired the IT HCI Technical Committee, and as a Senior Research Scientist at Boeing (USA). He was a faculty member of the Department of Psychology at Zhejiang University in China. Dr. Xu holds a Ph.D. in Human Factors/HCI and an M.S. in Computer Science, both from Miami University, USA., an M.S. in Engineering Psychology from Zhejiang University, and a B.Eng. in Engineering Physics from China university of Geosciences.

An internationally recognized expert in human factors and HCI, Dr. Xu is an elected Fellow of the International Ergonomics Association (IEA), the Human Factors and Ergonomics Society (HFES, USA), and the International Association for Psychological Science (APS). He serves as Senior Editor of  IEEE Transactions on Technology and Society and Associate Editor of  IEEE Transactions on Human-Machine Systems . He also sits on the editorial boards of the  International Journal of Human-Computer Interaction,   Theoretical Issues in Ergonomics Science, and the Journal of Applied Psychology . He is a member of the International Organization for Standardization (ISO) Technical Committee on Human-System Interaction (TC159/SC4) and its Standards Drafting Working Group (TC159/SC4/WG6).

With over 35 years of experience spanning academia and leading global IT and aviation companies, Dr. Xu has contributed extensively to research, design, development, and standards development in human factors and HCI. His work has received numerous research and design awards, with applications across multiple aircraft models and computing systems. He has co-developed over 20 human factors/HCI design standards for ISO, Boeing, and Intel, and authored three books— Engineering Psychology ,  User Experience: Theory and Practice ,  Human-AI Interaction, and a forthcoming book,  Handbook of Human-Centered AI . His papers have been published in core journals of human factors/ergonomics, HCI, psychology, aviation, computer science, and AI.

Since 2018, Dr. Xu has focused on the emerging field of  Human-Centered Artificial Intelligence (HCAI).   As one of its pioneers, he proposed the “technology-human factors–ethics (THE) triangle” HCAI framework (2019) and advanced the emerging domain of “human-AI interaction” (2020). He co-authored the influential paper titled “ Six Human-Centered AI Grand Challenges”  (2022) with Professors Ben Shneiderman, Gavriel Salvendy, and 23 other international scholars. In recent years, he has introduced multiple frameworks in the HCAI field, including Human-AI Joint Cognitive Systems (2021), Human-AI Joint Cognitive Ecosystems (2022), Intelligent Sociotechnical Systems (iSTS) (2022), the HCAI Methodological Framework (HCAI-MF) (2024), the Hierarchical HCAI  (hHCAI) approach (2024), the “User Experience 3.0” paradigm framework for HCAI (2024), Human-Centered Human-AI Collaboration (HC-HAC) (2024), and the HCAI Maturity Model (HCAI-MM) (2025). He participated in the development of two ISO standards for AI systems:  Ergonomics Issues of Robotic, Intelligent, and Autonomous Systems  (ISO 9241-810) (2020) and  Ergonomics of Human-Intelligent Systems Interaction (ISO 9241-812) (2024).
