HCI HUMAN FACTORS – COGNITION

COGNITION Cognition refers to the processes by which we (users) become acquainted with things or, in other words, how we gain knowledge Human/computer interaction is characterized as a dialogue or interchange between the human and the computer because the output of one serves as the input for the other in an exchange of actions and intentions. Early characterizations of the human-computer interface were more computer-centric. Displays are human-made artifacts designed to support the perception of relevant system variables and to facilitate further processing of that information. Before a display is designed, the task that the display is intended to support must be defined (e.g. navigating, controlling, decision making, learning, entertaining, etc.). A user or operator must be able to process whatever information that a system generates and displays; therefore, the information must be displayed according to principles in a manner that will support perception, situation awareness, and understanding.
