 Similar techniques were able to control robotic arms and simple joysticks.In 2009, researchers at the University of South Florida developed a wheelchair-mounted robotic arm that captured the user’s brain waves and converted them into robotic movements.The Brain-Computer Interface (BCI), which captures P-300 brain wave responses and converts them to actions, was developed by USF psychology professor Emanuel Donchin and colleagues.The P-300 brain signal serves a virtual “finger” for patients who cannot move, such as those with locked-in syndrome or those with Lou Gehrig’s Disease (ALS).
