An understanding of how both psychological and environmental factors mutually constrain skilled behavior is required to effectively support human activity. As a step toward meeting this need, a process model of skilled human interaction with a dynamic and uncertain environment is presented. The model was able to mimic human behavior in a laboratory task requiring one- and two-person crews to direct the activities of a fleet of agents to locate and process valued objects in a simulated world. The process model is a pair of highly interactive components that together mimic the behavior of the human-environment system. One component is a representation of the external environment as a dynamically changing set of opportunities for action. The second component is a dynamic representation of skilled human decision making and planning behavior within the environment so described. The process model is an expression of a general theory of skilled interaction assuming that perception and action mechanisms sensitive to environmental constraints are responsible for generating much of behavior, and where the need for additional cognitive processing of internal representations may result from environmental designs that do not adequately support the perceptual guidance of activity
