Read my mind ...
Researchers from the Fraunhofer Institute in Berlin and Charité, the medical school of Berlin Humboldt University in Germany, demonstrated a Brain-Computer Interface (BBCI) at CeBIT 2006 in Hanover, Germany. Users drive a cursor across a screen by imagining control of a mouse with their hand. Electrodes, attached to the scalp, through a special cap measure the electric signals of the brain; cerebral electric activity is recorded via the electroencephalogram (EEG).
Gabriel Curio, of Charité, says "users can operate the device just 20 minutes after going through 150 cursor moves in their minds. This is because the device rapidly learns to recognise activity in the area of a person's motor cortex, the area of the brain associated with movement. 'The trick is the machine-learning algorithms developed at the Fraunhofer Institute,' Curio says."
Additional images of the BBCI in use are available at the Berlin Brain-Computer Interface site.
