A joint team of researchers from Korea University and the Technical University (TU) Berlin developed an EEG cap that decodes brainwaves via an interface. TU Berlin Researcher Klaus Muller, one of the co-authors of the paper which explains the experiments, explained the process: “Exoskeletons create lots of electrical noise. The EEG signal gets buried under all this noise—but our system is able to separate not only the EEG signal, but the frequency of the flickering LED within this signal.” Although reporting overall success, the team did acknowledge that more work to create a less physically demanding experience for the target user is needed.​
