 We are from University of Warsaw, Faculty of Physics. What we developed is the brain-computer interface shown here and also explained on the board. That's the device that enables mainly disabled people to operate the computer, to communicate with the world without using muscles. So the person sitting here has not to move her arms, legs or anything just to operate the computer by looking at flashing fields. We also have implemented different modalities like the simple switch button and on P300 is our limit. What it really did is that the person can read the text, hear the music without any help of other people. She can just look for a while and then the music will play or the text will display and the pages will change so she could read on her own and watch the movie or something.
