The study of people using computers: a mixture of engineering, design, and behavioural science. HCI can be separated into four dimensions: the ‘task dimension’, dealing with goals and purposes of the engineers, designers, and the users of computers; the ‘dialogue dimension’, concerning how the computer and user are intended to interact; the ‘structural dimension’, dealing with specifics of the layout and the grouping of tasks; and the ‘usability dimension’, dealing with the ways in which users and computer actually interact. The human-computer interface is both the hardware and software of the computer and includes elements such as the keyboard, mouse, screen, graphical user interface, windows, drop-down menus, and other means of accessing information.
