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. Although brain-machine interface technology has traditionally focused on medical uses, makers like Hitachi and Japanese automaker Honda Motor Co. have been racing to refine the technology for commercial application.
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. Honda, whose interface monitors the brain with an MRI machine like those used in hospitals, is keen to apply the interface to intelligent, next-generation automobiles.
The technology could one day replace remote controls and keyboards and perhaps help disabled people operate electric wheelchairs, beds or artificial limbs.
