Paralysed people could navigate around buildings using a robotic wheelchair that can be controlled by thoughts alone.rnThe wheelchair is designed for people with severe neuromuscular disabilities, and can even be used in crowded or unfamiliar surroundings, says Javier Minguez, head of the team at the University of Zaragoza in Spain that is developing the chair.rnTo direct the wheelchair, users concentrate on one of several possible destinations in a 3D map of their surroundings, which appears on a screen in front of them. Users wear a skullcap with 16 electrodes positioned around their scalp. These detect millisecond-long fluctuations in brain activity, which happen when the user looks at the point on the screen that coincides with a target destination.
