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 humans. A significant number of large corporations and academic institutions are now studying HCI. Historically and with some exceptions, computer system developers have not paid much attention to the ease of use of the computer. Many computer users today would argue that computer manufacturers are still not paying enough attention to making their products "easy to use". However, computer system developers might argue that computers are extremely complex products to design and manufacture and that the demand for services that computers can provide has always exceeded the demand for ease of use.
An important factor of HCI is that different users form different conceptions or mental models about 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.
