As a follow-up to my post on Spatial Cognition in Virtual Worlds, researchers at Keio University have enabled a paralyzed man to control an avatar in the 3D virtual world of Second Life using a brain-computer interface (BCI). Three electrodes mounted on headgear monitor brain waves presumably from motor cortex, which is the area of the brain that is involved in the control of movement and is located close to the surface of the skull. The data is analysed, interpreted by computer algorithms, and then converted into real time movement of the avatar.
The implications of this proof-of-concept study in paralysis patients is great. A BCI application such as this one could be used in therapy, rehabilitation, and training interventions, which in turn could greatly improve the quality of life for these patients.
