Brain–Computer Interfacing (BCI) is a technology that allows a person to control a computer or other device with their thoughts. It works by measuring brain activity, such as electrical signals, and translating them into commands that the computer can understand. BCI can be used to control a variety of devices, including wheelchairs, prosthetic limbs, and even robotic arms. It has the potential to revolutionize the way people interact with technology and could be used to help people with disabilities or paralysis.
