This is freaking awesome. Those mind-control drone pilots we have today mean there's an exciting near-future for mind-machine interfaces. It will be fantastic not just for people who are paralyzed, but also perhaps we will have better prostheses, and maybe in the metaverse we will have additional appendages to do more tasks.

I am looking forward to our new world.

...which means that even a modestly sized transformer model could do significantly better.

with a big heap of "maybe". Signal could be a limiting factor, but also come on, more than 99% correct? That's above the level of a non-professional human transcriber in most situations. I'm not sure that typing I get more than 99% correct, I've made at least six errors typing this sentence alone (though it's quick to fix). The real improvement, it seems would be to speed and latency, looking at the diagram, the samp…

That's why I wrote "could," as opposed to "would" :-)

Interesting that the user has to think of specific letters to spell out a word. I guess the 26 distinct English letters are much easier to parse and separate than the untold thousands of words, especially when those words could be used in different contexts. I bet the next step wouldn't be to even parse words to make a sentence. It seems to me the next low hanging fruit would be to enable this machine to parse common…

A paralyzed man wrote a book by blinking when someone pointed at the right letter (sort of like how the guy stranded on Mars in book/movie The Martian sent messages to earth). This story was later made into the movie The Diving Bell and the Butterfly. https://en.wikipedia.org/wiki/The_Diving_Bell_and_the_Butter...

This process seems like it would be so much more efficient if he'd learned to blink in Morse code instead.

His first words were "I need more computing power"

"How about sending me a fourth gimbal for Christmas."

A friend of mine was a nurse on a mental health ward in the UK. There was a long term patient there who no-one could understand, until my friend, who was Mauritian, started working there. The patient was saying 'mes dents, mes dents'. (my false teeth, my false teeth..)

Long ago, the accuracy would decline as scar tissue formed around implanted electrodes. Not sure if that's changed in recent years as techniques improved.

How long ago is long ago? 7 years ago I took a course on the then-current state of the art for neural interfacing, and this was nowhere near a solved problem then. There was research going into emulating sea cucumbers, so the electrode could be stiff enough to penetrate the brain but then soften to avoid the build up of scar tissue. I think that research is still ongoing.

I remember reading about the problem in an article posted on HN a couple of months ago, so I don't think it's solved yet.

Total dystopian thought, but I wonder if this could ever be used to extract info people unwillingly, as in some interrogation scenario. I mean, you have a lot more control over what you say than what you think.

Yea, I actually consider the smaller FOV a feature. Doesn't necessarily have to be 45 degrees, but I'm not interested in covering my entire field of view. I want a monitor for work, not for games and movies. Immersion doesn't matter, but the comfort of not needing to cup my eyes sure does.

The whole point of VR is immersion. It's literally called Virtual Reality. What you seem to want is just a screen strapped to your head with some lenses to make it look further. Why do you want that exactly? Portability? Space saving?

Yeah I never said I want VR. I want head mounted displays to free me from bulky & expensive monitors that require lots of desk space and aren't available when travelling with a laptop. And if you can see around the HMD and reach for the coffee cup on the desk without having to look through cameras as you can with the glyph, I consider it a good design. Unfortunately the whole market seems to have developed around multimedia consumption and immersion.

I wonder how something like this would function with chorded typing? A keyboard like this [1] with only one key per finger I would imagine would be relatively easy (easier than handwriting even? Since it's not limited to only your finger muscles - you attach every easily controllable muscle in the body to a button on the 'keyboard', and it seems to be a binary value whether a finger is clicking down or not, instead of what letter your hand is writing) for a brain implant to register. And a lot faster than handwriting.

I'm just specifying the dimension where "better" would be relevant, I e. "Speed not accuracy"
