A brain-computer interface (BCI) is a form of interface that allows users to go directly from thought to a computer system.
In 2021, a BCI system that was designed for individuals with medical conditions that prevent use of their hands surpassed 18 words per minute.
BCI systems may be invasive (e.g., requiring electrodes or chips to be installed into the brain) or noninvasive (using external sensors located on the head or other part of the body).
BCI may someday enhance the use of various interfaces (and could supplement or enhance the prediction of things like gesture recognition systems). It may one day provide input back to the user.
