Brain implant translates paralyzed man's thoughts into text with 94% accuracy

A man paralyzed from the neck down, due to a spinal cord injury he sustained in 2007, has shown he can communicate his thoughts, thanks to a brain implant system that translates his imagined handwriting into actual text. The device – part of a longstanding research collaboration called BrainGate – is a brain-computer interface (BCI), that uses artificial intelligence (AI) to interpret signals of neural activity generated during handwriting. In this case, the man – called T5 in the study, and who was 65 years of age at the time of the research – wasn't doing any actual writing, as his hand, along with all his limbs, had been paralyzed for several years.

But during the experiment, the man concentrated as if he were writing – effectively, thinking about making the letters with an imaginary pen and paper. You can read more about this work HERE.
