Submission + - Hitachi develops brain-machine interface
Gary writes: "Forget the clicker: A new technology in Japan could let you control electronic devices without lifting a finger simply by reading brain activity. The "brain-machine interface" developed by Hitachi Inc. analyzes slight changes in the brain's blood flow and translates brain motion into electric signals. Underlying Hitachi's brain-machine interface is a technology called optical topography, which sends a small amount of infrared light through the brain's surface to map out changes in blood flow."
