The Paradigm of HCI: the Designer’s Role in Interface Design
The article centers round the description of the paradigm of the interdisciplinary scientific direction of human vs. computer interaction. The scientific and practical base of HCI makes it possible for the contemporary designers to create systems which allow solving applied tasks of users and, at the same time, being understood and easy to use, that is technically operationable and efficient. Historical stages of science maturation as well as basic directions of HCI development today are considered in the article. The scientific base of HCI is described as well as disciplines which contributed to its development. Three main groups of methodological approaches in science are considered, includingв the fundamental project method - the “task-artifact” cycle. A general classification of interfaces is presented. Main attention is paid to Graphic User Interface (GUI).The designer’s role in projecting GUI is presented; stages of the design process are described аs well as differences between the user experience (UX) designer, the interaction designer (IxD) and the interface designer (UI).
