Human–computer interaction or HCI is the study of interaction between people (users) and computers. It is often regarded as the intersection of computer science, behavioral sciences, design and several other fields of study. Interaction between users and computers occurs at the user interface (or simply "interface"), which includes both software and hardware, for example, general- purpose computer peripherals and large-scale mechanical systems, such as aircraft and power plantsuserother fieldshardware
