Man-computer interaction (commonly known as HCI) investigates the design and use of computer technology, focused on the interfaces between people (users) and computers. Researchers in the field of HCI, both observe the ways in which humans interact with computers and design technologies that allow humans to interact with computers in novel ways.
As a field of research, human-computer interaction is at the intersection of informatics, behavioral sciences, design, media studies, and several other fields of study. The term was popularized by Stuart K. Card, Allen Newell and Thomas P. Moran in his seminal book 1983, The Psychology of Human-Computer Interaction, although the authors first used the term in 1980 and the first known use was in 1975 The term implies that, unlike other tools with limited uses (such as a hammer, useful for nailing nails but not much more), a computer has many uses and this takes place as an open dialogue between the user and the computer. The notion of dialogue compares man-computer interaction with man-man interaction, an analogy that is crucial to theoretical considerations in the field.
An important factor in HCI is that different users form different conceptions or mental models of their interactions and have different ways of learning and maintaining knowledge and skills (different "cognitive styles" such as, for example, "left brain" and " people). In addition, cultural and national differences play a role. Another consideration in studying or designing HCI is that UI technology changes rapidly, offering new possibilities for interaction that previous research findings may not be applicable. Finally, user preferences change as new interfaces gradually become dominant.
