A formal definition of brain-computer interface (BCI) is as follows: a system
that acquires brain signal activity and translates it into an output that can
replace, restore, enhance, supplement, or improve the existing brain signal,
which can, in turn, modify or change ongoing interactions between the brain and
its internal or external environment. More simply, a BCI can be defined as a
system that translates "brain signals into new kinds of outputs." After brain
signal acquisition, the BCI evaluates the brain signal and extracts signal
features that have proven useful for task performance. There are 2 broad
categories of BCIs: implantable and noninvasive, distinguished by invasively and
noninvasively acquired brain signals, respectively. For this supplement, we will
focus on BCIs that use noninvasively acquired brain signals.
