Human Computer Interaction

Human-computer interaction (HCI) is the study of how people interact with computers and design systems that are usable, efficient, and enjoyable to use. HCI researchers study how people use computers, develop new technologies that let people use them in inventive ways, and evaluate the usability of existing systems. HCI is a multidisciplinary field that draws on research from a variety of disciplines, including computer science, psychology, design, and linguistics. HCI researchers use a variety of methods to study human-computer interaction, including user studies, usability testing, and ethnographic research. HCI research has played a major role in the development of many of the computer technologies that we use today, including graphical user interfaces, touch screens, and voice recognition. HCI research is also important for the development of new technologies, such as augmented reality and virtual reality.
