What Does Human-Computer Interaction (HCI) Mean?

Human-computer interaction (HCI) is the study and planned design of human and computer activities. HCI uses productivity, safety and entertainment to support and fulfill human-computer activities and is applied to various types of computer systems, including air traffic control, nuclear processing, offices and computer gaming. HCI systems are easy, safe, effective and enjoyable.

Techopedia Explains Human-Computer Interaction (HCI)

Humans interact with computers through a user interface. This includes software, such as what is displayed on the computer monitor, and hardware, such as the mouse, keyboard and other peripheral devices. As a result, the study of HCI focuses on user satisfaction. Attention to human machine interaction is important, because a poor interface can make it hard for users to benefit from even the simplest systems. In a corporate or factory setting, a poor user interface could have more severe consequences.
