Human–computer interaction (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, characters or objects displayed by software on a personal computer's monitor, input received from users via hardware peripherals such as keyboards mics and controllers etc.
The Association for Computing Machinery defines human-computer interaction as "a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them."
Human Computer InterfaceThe HID consists primarily of devices that are used by humans to control the operation of computer systems. Typical examples of HID class devices include:
- Keyboards and pointing devices for example, standard mouse devices, trackballs, and joysticks.
- Front-panel controls for example: knobs, switches, buttons, and sliders.
- Controls that might be found on devices such as telephones, VCR remote controls, games or simulation devices for example: data gloves, throttles, steering wheels, and rudder pedals.
Many technological innovations rely upon User Interface Design to elevate their technical complexity to a usable product.
