Brain-computer interface creates text on screen by decoding brain signals associated with handwriting
Using a brain-computer interface, a clinical trial participant was able to create text on a computer at a rate of 90 characters per minute just by thinking about the movements involved in writing by hand. Brain-computer interfaces use tiny electrodes to record signals in the brain. Credit: BrainGate.org.

PROVIDENCE, R.I. [Brown University] Researchers with the BrainGate collaboration have, for the first time, used an implanted sensor to record the brain signals associated with handwriting, and used those signals to create text on a computer in real time.
In a study published in the journal
Nature, a clinical trial participant with cervical spinal cord injury used the system to type words on a computer at a rate of 90 characters per minute, more than double the previous record for typing with a brain-computer interface. This was done by the participant merely thinking about the hand motions involved in creating written letters.
