Imagined Handwriting Becomes Fast Text
A participant with paralysis produced text at 90 characters per minute by imagining handwriting while an intracortical decoder recognized the neural patterns.
Earlier cursor keyboards required selecting letters one at a time. Decoding the complex motion of an imagined pen produced faster communication and showed that richer attempted movements could be easier for algorithms to distinguish. The study involved one participant and remained dependent on implanted electrodes and individualized training.
