A brain-computer interface (BCI), also
known as a brain-machine interface, is a system that allows a person to control
a computer or other electronic device using only his or her brainwaves, with no
movement required.
BCIs can be used for communication, computer access, or control of
devices such as a wheelchair or prosthetic arm, among other applications.
Virtually anything that can be controlled by a computer could, potentially, be
controlled by a BCI. BCI is being examined as a rehabilitation device to help
people re-gain motor skills that are lost from stroke, as well as a prosthetic
device to replace or compensate for motor skills that will never return.
