Brain-Computer Interface

A brain-computer interface (BCI) is a form of interface that allows users to go directly from thought to a computer system.

BCIs can be invasive (requiring electrodes or chips implanted in the brain) or noninvasive (using external sensors on the head or body).

In 2021, a BCI system designed for individuals unable to use their hands achieved over 18 words per minute typing speed. Potential applications include enhancing various interfaces, supplementing gesture recognition systems, and providing sensory feedback to users.
