Brain-Computer Interface

A Brain-Computer Interface (BCI), also known as a Neural-Control Interface (NCI), Mind-Machine Interface (MMI), Direct Neural Interface (DNI), or Brain-Machine Interface (BMI), is a direct communication pathway between an enhanced or wired brain and an external device.

Pronunciation

Brain-Computer Interface: /ˈbreɪn kəmˈpjuːtər ˈɪntərfeɪs/

Etymology

The term "Brain-Computer Interface" is derived from its function. "Brain" refers to the biological organ that is connected, "Computer" refers to the digital device or system that the brain is interfacing with, and "Interface" refers to the point where two systems meet and interact.

Definition

BCIs are often directed at researching, mapping, assisting, augmenting, or repairing human cognitive or sensory-motor functions. They are used for various purposes such as in medical research and applications, gaming, and other industries.
