Researchers Create Brain-Computer Interface That Allows Controlling Exoskeletons
- Using an electroencephalogram (EEG) cap, the newly developed 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).
“People with amyotrophic lateral sclerosis (ALS) [motor neuron disease], or high spinal cord injuries face difficulties communicating or using their limbs” explains Klaus Muller, an author on the paper. “Decoding what they intend from their brain signals could offer means to communicate and walk again.”
- It only took volunteers a few minutes to be training how to operate the system. Because of the flickering LEDs they were carefully screened for epilepsy prior to taking part in the research. The researchers are now working to reduce the ‘visual fatigue’ associated with longer-term users of such systems.
