Walking from Thoughts: Not the Muscles Are Crucial, but the Brain Waves!


Thoughts wander in VR

"Devices that allow for direct brain-computer communications are advancing on two fronts: devices implanted in the brain, and external electrodes that pick up the brain's electrical signals. In general the external devices are safer and cheaper, but the implants provide more control.

Typically, users are able to control their brain waves in a way that moves a cursor up and down and side to side on a computer screen.

Researchers from Graz University of Technology in Austria, University College of London in England, Guger Technologies OEG in Austria and the University of Graz in Austria have expanded the amount of control available via external electrodes with a means of detecting changes in brain signals when users imagine moving their feet and translating the effect into walking motion within a virtual reality environment.
