The design philosophy of human-centered AI(HAI) advocated by the computing technology and engineering community lacks comprehensive consideration of human factors/ergonomics.At the same time,the role of human factors-related disciplines in the research and development of AI has not been fully utilized.The present study proposes an extended HAI conceptual model,emphasizing that the development of HAI solutions needs to comprehensively consider the ethically aligned design,technology that fully reflects human intelligence,and human factors/ergonomics design.The related research and applications in recent years have been reviewed around the explainable,comprehensible,useful and usable AI issues from the perspective of human factors/ergonomics.Future work should be focused on research of the new human-machine relationship in intelligent systems,human-computer interaction modeling,applications of related psychological theories,development of human-computer interaction design standards,enhancement of existing human factors methods,and proactive participation in AI research and development.
