Digital tattoo lets you control devices with mind power alone (New Scientist):
“WHAT’S on your mind? For £79, anyone can buy a headset that reads the electrical activity of their brain. It’s called an electroencephalogram, or EEG, and you can use it to control devices with the power of your mind. But there’s a drawback: they don’t work when the wearer is moving and they look silly, so no one wants to wear them.
The solution could be a kind of EEG system that does away with the cumbersome electrodes, annoying gels and wires of its predecessors, replacing them with a flexible electronic skin that conforms to the body. It promises to let us monitor our brains discreetly 24 hours a day, and can be worn continuously for two weeks, staying put whether you’re swimming, running or sleeping…
Although Hidden EEG can’t rival the precision of the keyboard and mouse from your desktop computer, it is good for controlling systems in a more passive manner…it might start a coffee pot brewing in the morning when your brain activity implies you’re waking up. Or, if the device reads that you’re in a highly focused state, it could tell your phone to silence any notifications.”
