Brain-computer interface offers new control options for medical exoskeletons

19th August 2015

A new study has demonstrated the potential of a new brain-computer control interface to revolutionise the manipulation of medical exoskeletons.

Developed by Korea University and TU Berlin, the interface consists of an electroencephalogram cap that works with a lower limb exoskeleton by decoding specific signals from within the user's brain.

It allows users to move forwards, turn left and right, sit and stand by staring at one of five LEDs, each of which flickers at a different frequency and thus causes changes in neural activity when observed.

Healthy volunteers took only a few minutes to be trained how to operate the system, leading to hopes that it could be used to restore mobility for people with amyotrophic lateral sclerosis or spinal cord injuries.

Work will now be done to reduce the visual fatigue associated with long-term use of such systems.

Klaus Muller, an author on the paper, said: "Our study shows that this brain control interface can easily and intuitively control an exoskeleton system – despite the highly challenging artefacts from the exoskeleton itself."ADNFCR-8000103-ID-801798075-ADNFCR
