A Brain-Computer Interface for Controlling an Exoskeleton
From: Wireless Design & Development - 08/18/2015

Scientists working at Korea University, Korea, and TU Berlin, Germany 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).

Each of the five LEDs flickers at a different frequency, and when the user
focuses their attention on a specific LED this frequency is reflected within
the EEG readout. This signal is identified and used to control the
exoskeleton. [see Erich E. Sutter's 1992 article]
