(03/25/2026) Researchers with the VA Center for Neurorestoration and Neurotechnology in Providence, Rhode Island, developed an implanted brain-computer interface to restore rapid typing in paralyzed patients. Two participants, one with amyotrophic lateral sclerosis and one with a spinal cord injury, were able to reach typing speeds of 110 characters per minute, which resulted in 22 words per minute with a word error rate of 1.6%. This result resembles able-bodied typing accuracy and provides faster communication than even current, state-of-the-art, hand motor brain-computer interface systems. Typing with the device involves only attempting the familiar finger movements of using a standard QWERTY keyboard, with the computer interpreting the brain signals as keystrokes. The new interface provides an intuitive, easy-to-learn method for individuals with paralysis to regain the ability to communicate. (Nature Neuroscience, Mar. 16, 2026)
