Practical thought-controlled devices, such as wheelchairs, artificial arms, or even cars, are perhaps a step closer to reality thanks to research being carried out at Switzerland’s Ecole Polytechnique Fédérale de Lausanne (EPFL). Traditionally, brain-computer interfaces require the user to concentrate on constantly maintaining a mental command of either turn left, turn right, or no-command (go straight). According to EPFL, most users can’t sustain more than about an hour of the necessary mental effort. The school is developing a new system, however, that allows users to take breaks and shift their attention to other things while their thought-controlled device continues to operate on its own.
