A device that allows interaction between human being and a computer is known as a "Human-computer Interface". As a field of research, human–computer interaction is situated at the intersection of computer science , behavioral sciences , design , media studies , and several other fields of study .
A computer keyboard is a peripheral input device modeled after the typewriter keyboard [1] [2] which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches. Replacing early punched cards and paper tape technology, interaction via teleprinter -style keyboards have been the main input method for computers since ...
Electronic devices such as robots are increasingly able to recognise and mimic human emotion. Affective computing is the study and development of systems and devices that can recognize, interpret, process, and simulate human affects. It is an interdisciplinary field spanning computer science, psychology, and cognitive science. [1]
The computer case holds the motherboard, fixed or removable disk drives for data storage, the power supply, and may contain other peripheral devices such as modems or network interfaces. Some models of desktop computers integrated the monitor and keyboard into the same case as the processor and power supply.
