Researchers from Korea University and the Technical University of Berlin have developed a new brain-computer interface to control a lower limb exoskeleton by decoding specific signals from within the user’s brain.
A lower limb exoskeleton control system based on steady state visual evoked potentials.
Courtesy of the researchers.
Wearing an electroencephalogram (EEG) cap, the user can control the exoskeleton to move forward, turn left and right, sit and stand by staring at one of the five flickering LED lights.
Each of the five LED lights operates on a different frequency. When the user focuses their attention on a specific LED light, the system can extract the flickering frequency from the noisy EEG signal and control the exoskeleton.
The results were recently published in the Journal of Neural Engineering at http://iopscience.iop.org/1741-2552/12/5/056009.
