HCI as an independent branch of science that began to develop in late 70’s – early 80’s. It started with the recognition of problems that users of complicated and powerful systems were experiencing. Usability is based on research of communication theories, graphics, industrial design, linguistics, social sciences and cognitive psychology. This knowledge helps designers create technically efficient (i.e. enabling to solve assigned tasks) and user operable (i.e. users can solve tasks) systems.
