By enabling users to communicate and control devices with their thoughts, brain-computer interfaces (BCI) hold almost a scary amount of potential. While they have achieved feats such as directing the flight of a quadcopter and helping victims of paralysis to communicate, sufferers of brainstem stroke with “locked-in” syndrome have so far been beyond reach. But now, a researcher at East Tennessee Sate University (ETSU) has demonstrated BCIs may in fact give brainstem stroke patients a voice again, with very specific brainwaves serving as a typing finger for a virtual keyboard.
