HATOYAMA, Japan - Forget the clicker: A new technology incould let you control electronic devices without lifting a finger simply by reading brain activity.
The "brain-machine interface" developed byInc. analyzes slight changes in the brain’s blood flow and translates brain motion into electric signals.
A cap connects by optical fibers to a mapping device, which links, in turn, to a toy train set via a control computer and motor during one recent demonstration at Hitachi’s Advanced Research Laboratory in Hatoyama, just outside.
"Take a deep breath and relax," said Kei Utsugi, a researcher, while demonstrating the device on Wednesday.
At his prompting, a reporter did simple calculations in her head, and the train sprang forward a€" apparently indicating activity in the brain’s frontal cortex, which handles problem solving.
Activating that region of the brain a€" by doing sums or singing a song a€" is what makes the train run, according to Utsugi. When one stops the calculations, the train stops, too.
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.
