Scientists working have developed a brain-computer control interface for a lower limb exoskeleton by decoding specific signals from within the user's brain using an electroencephalogram (EEG) cap. The system allows users to move forwards, turn left and right, sit and stand simply by staring at one of five flickering light emitting diodes (LEDs), according to the paper in the Journal of Neural Engineering. Each of the five LEDs flickers at a different frequency, and when the user focusses their attention on a specific LED this frequency is reflected within the EEG readout. This signal is identified and used to control the exoskeleton. read more
