HUMAN COMPUTER INTERACTION (HCI)

Human Computer Interaction (HCI) is defined as the study of interaction between people (users) and computers. It is often regarded as the intersection of computer science, behavioral sciences, design and several other fields of study. (Wikipedia, 2013) HCI is a discipline concerned with the design, evaluation and implementation of interactive computer systems for human use and with study of major phenomena surrounding them. (ACM SIGCHI, 1992)

(Compter, n.d.), Human-Computer Interaction, a discipline concerned with the study, design, construction and implementation of human-centric interactive computer systems. HCI (human-computer interaction) is the study of how people interact with computers and to what extent computers are or are not developed for successful interaction with human beings. (Rouse, n.d.)

Human Computer Interaction (HCI) is an area of research and practice that emerged in the early 1980s, initially as a specialty area in computer science embracing cognitive science and human factors engineering. As computers become more and pervasive in culture, designers are increasingly
