High-performance brain-to-text communication via handwriting | Nature

A brain–computer interface enables rapid communication through neural decoding of attempted handwriting movements in a person with paralysis.

Subjects Brain–machine interface Motor cortex Abstract Brain–computer interfaces (BCIs) can restore communication to people who have lost the ability to move or speak. So far, a major focus of BCI research has been on restoring gross motor skills, such as reaching and grasping 1 , 2 , 3 , 4 , 5 or point-and-click typing with a computer cursor 6 , 7 . However, rapid sequences of highly dexterous behaviours, such as handwriting or touch typing, might enable faster rates of communication. Here we developed an intracortical BCI that decodes attempted handwriting movements from neural activity in t
