Brain-computer interface enables “locked-in” brain stroke sufferer to communicate

With a model of a computer keyboard positioned in front the user, they were advised to focus on the key that they wanted to type. The BCI then randomly flashed numbers and letters in front of their eyes in quick succession. When the item the user is focusing on flashes, a P300 occurs, with the computer then recognizing this as selection of the key and compiling the words the patient wished to communicate. The patient was able to correctly spell words and communicate with family members in 40 out of 62 sessions with the BCI.

Excellent.
