People with paralysis navigate a room via a mind-controlled wheelchair

Three people with paralysis of all four limbs used their thoughts to steer a wheelchair through a cluttered room with a reasonably high level of accuracy. This suggests people with paralysis could move independently through certain rooms, but the technology may not be advanced enough to navigate a busy street. A range of different researchers have previously used two main strategies to test mind-controlled wheelchairs on non-disabled people. The first involves a person focusing on a flickering light in a particular location. This generates brain signals that an artificial intelligence translates into wheelchair movements towards that location, but this approach often leads to eyestrain.
