HUMAN COMPUTER INTERACTION

                             

                              

                                  Human-computer interaction (HCI) is the field of study that focuses on optimizing how users and computers interact by designing interactive computer interfaces that satisfy users’ needs. It is a multidisciplinary subject covering computer science, behavioral sciences, cognitive science, ergonomics, psychology, and design principles. The emergence of HCI dates back to the 1980s, when personal computing was on the rise. It was when desktop computers started appearing in households and corporate offices. HCI’s journey began with video games, word processors, and numerical units. However, with the advent of the internet and the explosion of mobile and diversified technologies such as voice-based and Internet of Things (IoT), computing became omnipresent and omnipotent. Technological competence further led to the evolution of user interactions. Consequently, the need for developing a tool that would make such man-machine interactions more human-like grew significantly. This established HCI as a technology, bringing different fields such as cognitive engineering, linguistics, neuroscience, and others under its realm. Today, HCI focuses on designing, implementing, and evaluating interactive interfaces that enhance user experience using computing devices. This includes user interface design, user-centered design and user experience design.
