90 cpm!
99% accuracy!
Wish this was available decades ago, but hopefully it will eventually become easily available.

The EEG spellers work better and are more established. What blows me away here is that it is an implanted microcomputer in the motor cortex and the associated code to analyze the neuronal activity there. IOW people who know how to write, but can't write because of trauma or disease can write by *trying* to write....writing mentally, just like they used to do before paralysis. That is some nifty code running on some cool hardware.
I remember as an adult, a BYTE magazine handwriting analysis contest (if anyone else remembers that contest please correct my recollection details, if necessary). Basically, they provided writing (or letters) samples - something like in .bmps or similar. You wrote your software to analyze those. Then they tested your software against other samples - and nothing outrageous at all. My recollection was that the results were...umm..disappointing and incredibly slow...and those were the top entries...the winners :)
That is how far we have come in less than one adult's lifetime and it is pretty cool. So, I figure, it is compelling to give a lot of attention to the latest ransomeware debacle and the like, but I sometimes forget how much cool stuff is going on.

The discovery was made many years ago, by a monkey. :)
Not kidding. It was an experiment to listen and interpret neural pulses with some electrodes implanted in a monkey's brain. Seen that in a video from the dawn of youtube era, couldn't find it any more, probably reported for animal cruelty and taken down. At some point the human researchers started to understand the neural pulses, and made the game to respond to the monkey's brain instead of responding to the joystick controller.
The monkey figured out pretty fast that the game can be controlled only by "thinking" at moving the joystick, without actually moving the joystick. Imagine the monkey chilling in front of the screen, and winning every game without moving a finger. ;D
The awe on the researcher's face must have been priceless. :-DD
About the neural pulses recognition and translating that to text, that's nothing fundamentally new, just classic machine learning trained for the given patient.
The major drawback is that it requires electrodes implanted in the patient's brain. :scared:
