Hitachi company in Japan has invented a technology which can control electronic devices without any physical effort but just by reading your brain activity.
The newly developed "brain-machine interface" technology can analyze the changes in blood flow in brain and interpret the brain emotions into digital signals.
The brain-machine interface technology has originally developed for the use in medical analysis and research but now its prospective use in other fields and its potential commercial implementations are being studied by other companies like Honda Motors as well.
Hitachi's scientists are developing 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.
Initial uses would be helping people with paralyzing diseases communicate even after they have lost all control of their muscles.
