Virtual reality study electrodes
A research project at the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland is looking at the effect virtual reality has on people's perceptions of themselves and their bodies.
Professor Olaf Blanke, a neurologist at the EPFL's Brain Mind Institute, is leading the Real Avatar project to improve understanding of self-awareness through cognitive science, virtual reality and brain-imaging technology.
Subjects are immersed in the body of an avatar using a virtual-reality headset and their brain electrical activity is monitored by electrodes fitted to a skullcap, shown above, as they are exposed to different 3D environments controlled by the researchers.
