It may sound like a science fiction but researchers are toying with a mind-controlled device that enables users to fly a model helicopter with just thoughts!

The device allows human subjects to control the flight of small, remote-controlled helicopters using only their minds.
Researchers at University of Minnesota in Minneapolis, US, have created a brain-computer interface.
This system allows the brain to communicate directly with an external device that lets participants control the path of a flying object - known as a quadcopter - simply by thinking about specific movements.
"The technology could one day help people with disabilities lead more independent lives," said Bin He, a biomedical engineer and the project's lead scientist.
How does it work?
