We recall the development from Cyber-Physical-Systems (CPS) to Human-Cyber-Physical Systems (HCPS) in past two decades. We shall clarify some concepts and discuss major challenges from system engineering perspectives. We argue that, to advance the research and development of HCPS, we need a novel theory of human-cyber-physical computation, which can be seen as revised ubiquitous computing. To develop engineering systems of human-cyber-physical systems, we propose the research on contract-based architecture modelling to support model-driven construction and evolution of HCPS, and the development of technology for software defined HCPS. Based on the system architecture, we argue for controllable, composable and reusable (i.e. trustworthy) AI systems to advance the system engineering of HCPS. The talk is based on the proposal for the China National Science Foundation Key project proposal on Theory of Modelling and Software Defined Method for Systems of Human-Cyber-Physical Computing in collaboration with Professors Wei Dong, Miaomiao Zhang and Guanjun Liu.
