Brain-computer interface helps paralyzed patient write text messages

“Mindwriting” may sound like science fiction, but the future is here.

I’ve learned recently that a patient who is paralyzed from neck down, was able to communicate in real-time — forming complete sentences — simply by using his mind!

Through new developments in brain computer interfaces (BCI), scientists implanted two tiny sensors on the outer layer of the participant’s brain that detects activity as he mentally visualized the handwriting movement. An algorithm decodes the motion for each letter and translates it into text which appeared on a computer screen.

Essentially, he can “text” as fast as any able-bodied person can, and I am just in awe at this groundbreaking technology. While more work and research needs to be done, this new brain-to-text system will help millions of people suffering from paralysis in the coming years.
