The P300 is a response of our brain to a rare event such as the flashing of a letter your waiting for on a screen. Each time a letter flashes, your brain generates a p300 response, which the computer picks up and recognizes what letter you were looking at. This interface is originally thirty years old that flashed in rows and columns but Dr. George Townsend, an associate Professor at Algoma University made contributions to this field which were to note the problems in that specific way. It’s not row and column based but a random pattern designed to improve the speed. This is a slow interface, which is used in hospitals that is designed to help ALS patients.
