Thought-controlled computer cursor

On each side of the screen, a monkey moves a cursor with its thoughts, using the cursor to make contact with the colored ball. On the left, the monkey's thoughts are decoded with the use of a mathematical algorithm known as Velocity Kalman Filter. On the right, the monkey's thoughts are decoded with a new algorithm developed at Stanford, known as ReFIT, with better results. The ReFIT system helps the monkey to select 21 targets in 21 seconds, as opposed to just 10 with the older system in the same time.
