That's roughly about one word per second... that's pretty good! :D

It's above the average typing speed at least

It actually makes me wonder what the upper limit for human thought -> text entry is. I imagine it will be much higher than typing or speaking once the technology is refined. Ultimately this may drive healthy people to get an implant.

I think the upper limit will be beyond anything relating to language, like speaking or even thinking words. It'd be something like transcribing thoughts themselves from abstract forms into words.

I would love for somebody to transcribe the particular fuzzy images of people I imagine the same every time as my mental concept of actions like "driving" or "football". I'm pretty sure they're people contorted in ways that are impossible. But I can't even remember the image after it connects my thoughts, it's like a dream. Am I the only one?

We actually have an early brainwave to images ai now, release was a few months ago. Still needs a few years before it'll do arbitrary images though.

Yeah. Or me imagining a 3d printed object and CAD software creating it for me

I’m not sure what the upper limit for human thought is, but I’m sure 3.5g of magic mushrooms will take you towards it.

Probably not. Research on speed reading has mostly supported the idea that the rate at which we naturally speak is the limit to which our brains can meaningfully process information. That is, while you can train yourself to understand text and speech a bit faster than normal, “speeding” through pages of text in a second isn’t any better than untrained skimming. Getting rid of “subvocalization” (I.e that inner voice many hear when reading), as many advocates of the method propose, does nothing to change that.

In other words, with a bit of training I suspect you might be able to output text like the micro machines guy, but none of it would have any meaningful thought behind it. That is, two people would not be able to have a “sped up” conversation, nor would it let you output a book any quicker.

Eh I disagree

The rate at which I speak is much slower than what I can think in words

But more over, I mostly think in multiple streams of thought and images. There's so much information that I can try to pack in at one time

Yes, the people trying to understand me would be the bottleneck... But if we're just talking creating, I can type very fast (love 120+ WPS) but my brain can still go much faster than that

Plus you'd be thinking mostly in words rather than letters. You would just say "cat" and it would know. Instead of C...A...T...

No evidence that the thought speed isn't a learned limit through speaking.

I typically watch tv at 2-3x speed and suspect that i'd be able to close to 2x speed if my tongue were more nimble. In Japanese i convey information probably 1.5x the speed i do in English (my native language). Simply because it supports faster speaking.

There is.

Average syllable count per second varies across languages. But when the linked study looked at how fast information is actually conveyed they all do so at roughly the same rate.

Was curious who developed the BCI, per article “The brain-computer interfaces that Shenoy’s team works with involve a small pad of sharp electrodes embedded in a person’s motor cortex, the brain region most involved in movement. This allows researchers to record activity from a few dozen neurons at once and find patterns that reflect what motions someone is thinking of, even if the person is paralyzed.”

Similar to neuralink and other BCI startups this is a surgical component imbedded through the skull. With companies like synchron which are developing a stent like BCI that is much less invasive surgery it will be interesting which becomes the go to form of BCI for the disabled.

Right now I think the go to company is Blackrock Microsystems, I think they have the most implanted BCI systems in humans patients out of all the companies. It’s weird how neuralink gets all the sensationalism when they’re quite far behind from Blackrock and other companies.

Can someone ELI5 this for me: how does sticking a wire in someone's brain actually communicate their thoughts to a computer to type?

27

fatbunyip t1_j62mnvv wrote

Basically it's many very small wires that can pick up signals from small clusters of neurons in a specific area.

The idea is that the activity in the neurons when you think "move hand left" is different to when you think "move hand right". So once it's installed, you can get the person to think something, record the brain activity, and then you build a map of what brain activity matches what actions.

flusteredpie t1_j62x8k6 wrote

Interesting. Does it ever require recalibration or are the signals constant with age?

13

martland28 t1_j63l7l7 wrote

There’s not yet a universal calibration application so each BCI system is calibrated for each patient. Furthermore, yes, sometimes recalibration is necessary if the intended outcomes are bit off from what was expected.

It doesn't read their thoughts per se. It detects signals from their motor cortex. When you speak that part of your brain tells your tongue, mouth, throat, ect to move in certain ways. Even though these signals don't make it to those body parts when a person has ALS, they are still there. The implant detects those signals and can tell what the person was trying to say.

Do you think they cheated and literally typed the phrase “62 words per minute?”

It looks like they have to mime their words to the screen. Pretty cool still, no need for all that voice/gesture accessibility apps or guide programs.

It could just go straight to voice synthesis if they really wanted it to. With modern deep fake tech, it would even sound like him.

What you can do now is record your voice before the disease takes your ability to speak. Then, when you need to use a text-to-speech program, it can use your real voice, rather than a generic one.

Wonder what the error rate is, probably pretty high or they would tout it. All this article states is that tapping into more neurons improves it, no published numbers though.

Fairly certain the controversy regarding Musk and Neuralink relates to the vaporware promises of downloaded consciousness.
