Human-automation interaction is the study of how human operators and automated systems divide functions and exchange control authority in complex sociotechnical systems, addressing how the allocation of tasks between human and machine affects performance, situation awareness, trust, mental workload, and operational safety ^[1]. A central conceptual framework decomposes automation into four classes of information-processing functions—information acquisition, information analysis, decision and action selection, and action implementation—and assigns to each function a graduated level of automation ranging from full manual control at one extreme to fully autonomous machine action with no human notification at the other ^[2]. The design problem is to select the appropriate level of automation for each function rather than automating maximally, because excessive automation can lead to loss of manual skills, overreliance, mode confusion, and reduced ability of the human operator to detect and recover from failures of the automated system, particularly when that automation is unreliable ^[3].
