Researches the design and use of computer technology, focusing particularly on the interfaces between people (users) and computers. Researchers in the field of HCI bothobserve the ways in which humans interact with computers and design technologies that lets humans interact with computers in novel ways.
Humans interact with computers in many ways; and the interface between humans and the computers they use is crucial to facilitating this interaction. Desktop applications, internet browsers, handheld computers, and computer kiosks make use of the prevalentgraphical user interfaces (GUI) of today.
Human-Computer Interaction studies the ways in which humans make, or make not, use of computational artifacts, systems and infrastructures.
