We print by the power of thought - the brain interface

In early April, Adam Wilson posted a status update on his twitter account. And no, he didn’t use a keyboard or a Twitter client hidden under Excel for that - he sent a new status with the power of thought!

Principle of operation

The interface consists of a keyboard displayed on the screen. The principle of work lies in the fact that each letter flickers in its own way, and if you look at the letter “A” on the screen and all other letters flicker, then nothing happens. But when this “A” flashes, the brain exclaims: “Something is wrong here, something changed when I watched this letter.” And in this way, brain activity can be seen with the help of EEG, and therefore it is possible to determine what this letter was.
