Writing with the mind

Mind reading isn’t so difficult to do after all. Researchers at the VA Medical Center in Cleveland, OH used a computer model to recreate the mental images a paralyzed volunteer had of alphabet letters.  “Using a brain-computer interface, the volunteer was asked to imagine the motions involved with writing the letters of the alphabet. The associated brain activity trained the neural network, which is a series of algorithms that recognizes patterns, to decipher the commands and trace the imagined motions of the hand.  After training, the model could decipher the letters envisioned by the volunteer with a 95% rate of accuracy and at a speed of 66 characters a minute — for scale, average handwriting speed is 120 characters a minute.”  MORE WITH VIDEO
