The "brain-machine interface" developed by Hitachi Inc. analyzes slight changes in the brain's blood flow and translates brain motion into electric signals.Not clear what happens if you require a calculator to solve the problems.
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.
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 Tokyo.
At his prompting, a reporter did simple calculations in her head, and the train sprang forward - apparently indicating activity in the brain's frontal cortex, which handles problem solving.
Activating that region of the brain - by doing sums or singing a song - is what makes the train run, according to Utsugi. When one stops the calculations, the train stops, too.
Hitachi's scientists are set to develop a brain TV remote controller letting users turn a TV on and off or switch channels by only thinking.For those of you that are looking for a way to watch TV and burn even fewer calories, hold tight, help is on the way.
