Human - computer interaction (HCI) is the area of intersection between psychology and the social sciences, on the one hand, and computer science and technology, on the other.HCI researchers analyze and design-specific user-interface technologies. HCI continues to provide a challenging test domain for applying and developing Psychology and interactive system design.
HCI is a science of design. It seeks to understand and support human beings interacting with and through technology. Much of the structure of this interaction derives from the technology, and many of the interventions must be made through the design of technology. HCI is not merely applied psychology; it has guided and developed the basic science as much as it has taken direction from it.
