They have learned to use their thoughts to steer a model helicopter around a gym, making it dip, rise, turn, and even fly through a ring. The scientists have published their study in the Journal of Neural Engineering. The development of brain computer interfacing (BCI) is to provide the user with the ability to communicate with the world outside and manipulate objects through thought modulation. Achieving this is accomplished...
