We print with the power of thought - brainwitter interface

In early April, Adam Wilson posted a status update on his twitter. And no, he did not use the keyboard or the Twitter client hidden under Excel - he sent a new status by the power of thought!

Principle of operation

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