Now the remaining problem is to make Magnetoencephalography devices affordable and not insanely huge.

The size of that machine

It's worth noting that this isn't new technology. This paper is specifically about how their new technique provides a small but statistically significant improvement on existing techniques. The fact that they provide code and dataset is really praiseworthy.

why is there no live demo? Anyone seen this in action? Can someone share a demo video or something

So attended an interesting talk a couple years ago: - fMRI and/or brain implants are the best to figure out brain waves - but they are expensive or invasive - EEG is a lot cheaper and easier but not as precise - BUT what if you used LLMs to analyze EEG data taken at the same time as brain implants etc The answer seemed to be that "yes, you can get better than traditional EEG data using EEG + LLMs". Curious to see where this ends up and hopefully not that like that Black Mirror episode with the brain scanning leading to murders.

Someone should try it while sleeping and see if anything is related to a dream.

Interesting -- really excited for the future of human-brain interfaces and just in general more interface exploration enabled by large transformers. I'm already very excited by voice, although wish I could get something akin to the subvoc common in scifi novels. Seems like it would be an easier path than human-brain and would allow me to use voice models in public. As an aside, disappointed by the very low quality of comments on this article here.

[stub for offtopicness] p.s. come on you guys - this is not what HN is for. You may not owe $megacorp better but you owe this community better if you're participating here.

And you reverse it to go from words to brain waves! Mind reading at a distance.

great news!, I would like to conversate with my dog...i'm sure he has more important thing than lots of people

Reminds me of the scene in series Incorporated where a megacorp uses this sort of tech to interrogate an employee from a competitor mega-corp to get at a trade secret. It's a little spooky how real that could now be. Oh and that series was a dystopian series because ofc it was

I still think of this video often and wonder if it is building on any of that technology, almost 10 years old now. Just looking at this whitepaper it seems like they both use some kind of infrared transcranial light, but never imagined the machine in the original iteration was so big [Regina Dugan's Keynote at Facebook F8 2017 | Inverse] https://www.youtube.com/watch?v=kCDWKdmwhUI

One practical application comes to mind: [China’s Robot Juggernaut Unitree Debuts a $650,000 Personal Gundam ]( https://gizmodo.com/chinas-robot-juggernaut-unitree-debuts-a... )

Please see my bio for the full rant. The key take-away is: > While we missed the boat on Internet tracking, there is still time to avoid sailing through the final frontier of neural tracking. > Thanks to the BCI, we will soon be offered the trade of our privacy for the convenience of password-free login and faster typing. Next, there will be a quick TSA neural scan prior to boarding...

There were alpha block classes

Are they trying to infer characters/words from brain waves? I would have thought the brain is thinking in concepts rather than actual words

I hate this because we have crazy billionaires who want to abuse this technology. But apart from tht it's pretty cool, though I hate that it's being developed in this dark day and age. Miserable times.

Mark always been framed/stated for stealing user's data or invasing user's privacy but apart from these, this guy has always been one step ahead in making new research, technology possible by experimenting new things. First with the AR/VR which didn't work I guess so he pivoted from that to Rayban glasses, and now this.
