Upgrade Your Hand With This Extra Thumb 

A 3D printed thumb is insane right?! 🤯 What other scientific inventions would you love to see in the future? 👀👇

That's one way to make AI art more realistic.

I have no other option but to give this two thumbs up

These people really need to collaborate with the woman who made the mind-controller for video games. Imagine the prosthetics we could make with that!!

Easy to use, easy to attach. This is a neat implementation for the initial idea. Good work! I would be looking forward to the creator's ideas and inventions.

Fascinating. As a Hand Surgeon, who focuses much on basal joint arthritis, of the thumb, this certainly can help those patients although my focus remains on eliminating that pain and helping the excellent thumb we already have.

Omg this is so cool to see Dani in a video 5 years later. I remember first seeing her around 5 or 6 years ago on Bloomberg, insider or maybe buzzfeed showing her invention in early stages. It's awesome to see her still in the field and the commitment she's made to stay in it. Admittedly, at the time of first upload this tech was kinda new and I was a bit skeptical. I'm happy to report today, I could not be more happy to have been proven wrong :))

1950s: In the future, I believe there will be a flying car. 2023: Haha, extra thumb.

Anyone who has used VR can attest to how flexible the human brain is at augmentations. I constantly try to turn around my real body using VR controls if I've gotten turned around and now the cable is rubbing against my leg.

She is so invested. You can tell she's all in.

Haha funny but really clever idea! (And not really relevant for context, but I would just like to point out that I find the personal style of the designer absolutely epic)

I wonder how long it would take for the brain to fully learn to coordinate the new thumb with an existing hand. I also wonder how removal of the new thumb will feel afterwards.

Is the Design Open Source? If not can it be released under a CC License? I would LOVE to print one, and collaboration can push all this forward!

I've been writing a fantasy book where one of the races in it actually does have two thumbs on each hand, and this video just gave me a WHOLE lot of context too not only how would that race grab and interact with things with their extra thumb, but also how the brain will work with it and a great opportunity for me too personally see what it's like (quick explanation too why I mentioned the brain for a fantasy book; while I was aiming for straight fantasy, I somehow ended up marrying fantasy and sci-fi together for it. That's why I mentioned the brain.). Thank you Great Big Story for uploading this video and thank you RU-vid Recommendations for suggesting this video. =) Have a nice day everyone. =)

Can you imagine if this becomes normal in twenty years? Everyone walking around with extra digits.

I'm not going to lie, I'm usually a snobby engineer that would look down on arts students (mostly jokingly) but this just opened up my eyes to so much more. Thank you GBS and Dani

This could be mass produced today with a few design tweaks; slightly stretchy gloves in a few general sizes...so they stretch to firmly fit. And a liquid and dust resistant cover over the Robotic Thumbs so they are fairly easy to clean. Using a Brain Scanner to control a Mouse Cursor or some mechanical device does work...but takes dozens of hours per person to learn what the Brain Scanner is sensing specifically...then put part of the brain in the one or a few states that correspond to Left/Right Motions, Up/Down Motions, Left Mouse Click or Click and Hold, Right Mouse Click or Click and Hold, etc. So it works but there is a long learning process for both the Human and the Computer Program to 'understand' or to react predictably to specific Brain States. But this? Most Humans who are not paralyzed from injury, can reliably move their Big Toes individually and reasonably precisely around the time they learn to stand up and walk. So the mass produced version of this 'extra thumb' could be sold as one cheaper version of what is shown since it's mass produced; a 'glove with electromechanical actuators for the extra thumb' + a sock that very precisely measures motion and relative position of one Big Toe. Or the more expensive version would be one extra thumb for each hand...linked to the right Big Toe for the Extra Right Thumb, and linked to the Left Big Toe for the Extra Left Thumb. But there is another market for this idea; anyone missing a hand could have one sensor on one Big Toe, and another on their other Big Toe. Moving Big Toes would control two fingers as a single action; apposing fingers for a new cheaper and easier to learn way to control prosthetic hand/fingers. It will take multiple product generations to get something I am trying to describe that is at a middle class cost...but this is such a straightforward idea that High School Robotics Clubs could try to make their own version of it, so in 20 years there should be some very cool versions.

Until now, I didn’t think I needed a third thumb, but now I’m wondering what it’s like.

How many times have we felt we needed an extra hand? This could be the next best thing.

Some of us have used our feet like hands most of our life, so this toe control seems natural

O mundo precisa de mais cientistas malucos como essa mulher.

Dani and Stuart have great chemistry.

Omg I want one or two! They would be so helpful in my work! Love and light!

This is amazing! Humanity has come a long way in the past 100 years.

This is awesome! But you should add a soft silicone bad to it for gripping smooth objects

As a piano player this would be so freaking helpful

Awesome stuff, Dani. Keep using that big brain to help enrich other's lives. Bravo.

Can't wait to see Doc Ock become a real thing.

Bro's gonna end up like Doc Ock 💀

now we've seen a updated video on this, we need so see one on that vibrating glove that teaches your piano passively.

There seems to be a great many studies and innovations that pertain to the hand but in comparison not so much for improving the part(parts)that are our means of getting around.

I thumbsed up this 20 seconds in. Amazing

Dexterity, and great hand/eye coordination are priority in histology. I wonder what this could add to what I do at work.

I had the Sixth Finger toy as a kid... this is even cooler!

Humans are going to be so interesting in the future. Extra fingers, brain implants, virtual physical immortality, just straight up sci fi stuff haha

When will these be available for commercial purchase? Like this sounds like it’d be great for every day use.

dude this is so sick!

I was born with an extra finger on my right hand, sadly it didn't have Muscle use so it was removed at a Very young age but hey, got a fun little lump/nub of its presence.

The great big story has come back!

Is it still a concept or where do they sell them. I need two of those.

This is amazing

Touching myself with this is going to be .... Two thumbs up

very cool, but where or when we will be able to buy one? looks so cool tbh

Sell the hardware kit please!!! Looks like a fun project to mold one to ones own hand

But this is only seeing how we react with things now after adding the thumb. I would be far more interested in seeing how things would be now if we had already had the extra thumb. What would tools look like etc.

cool i can see it being usefull for a lot

“We’re going to test your brain” “…cool” 😂

I have wondered why we don't have an opposing opposable thumb. There's even a perfect spot for it on the palm already

Now that's the future, The blink of the future. We need things that add to our abilities.

Clever lady. Full marks.

Can we get STL, or instructions for building this?

Love it

Beautiful, ill take two

My husband has always had the use if one hand... and it's wearing out. I wonder if this could help him.

Most people dont fully utilize the appendages we have. I still want extra appendages tho. Can i get a prehensile tail, please?

Where can I download the STL? /s

I want one also I love her suit, but the cuff on the white side should be black, It bugs me

When do we get a piano concerto for the third thumb, third thumb jazz players and ‘thumb metal’?

After this vid I immediately watched the outer limits episode the 6th finger with the late David McCallum:)

Good idea, another finger i have no use for beyond the initial 4 on each hand.

Oh, that’s very handy.

Can i use it for doble tap HP in street fighter?

6:41 feels so wrong, but looks awesome 🤘🤘😂

I give this video 4 thumbs ups!

Where can I get one!?

I’ve actually noticed that I sometimes hold things like the extra thumb but with my pinky.. it sometimes works lmao

This human enhancement tech is giving major Machamp vibes. Very cool.

Every time I see some shit like this I just imagine Squidward writhing on the ground screaming "FUUUTUUUURE"

finally one step close to me having a extra pair of arms.

Imagine the possibilities for thumb wars

when can I buy this???

Great, it frees my others to pick my nose with...

interesting. is it hard to learn to use it while u walk? if it gets hardy enough upgrades imagine the parkour applications

I want a third thumb.

I feel like if someone attached an artificial tail in our back and connected it to our spine, we would be able to control it without much training. I think our monkey brains still have some data stored somewhere on how to do it. I can almost feel it, when i try to immagine it, at least the muscles that are close to the butt, much more than when i'm immagining an extra limb, so i'm not sure it's just placebo

anyone else reminded of stelarc’s artwork 3rd hand?

Damn didn’t realise you could literally buy new body part upgrades now

Like in 2077, what would stop people from adding a new bionic limb? And is that a good or bad thing? And would there be drm in the new limb? So many questions we have to answer in the court of law.

"here is no truth in flesh, only betrayal. There is no strength in flesh, only weakness. There is no constancy in flesh, only decay. There is no certainty in flesh but death."

Finally, a way to make xenomorph and halo elite cosplays more realistic.

imagine how many joints you could roll with this

Bruh those who had extra fingers inborn upon watching probably felt like they have the god rng of all time 😂

since so much of this technology has been popping up recently, i really hope to see people with like 4 arms on the street some day

I need that

Waiting for that day when a mad scientist showcases machine tentacles...

Perfect for my nose

This research team should study or work with top ranking online gamers and Twitch streamers, especially the ones who review multiple different types of consoles, gaming rigs, gadgets and so on. My guess is that Gamers' brains have to the most neuroplastic with respect to psycho-motor coordination. Disabled gamers or gamers who have sustained Repetitive strain injuries or even just injuries on their playing limbs or digits would make even better candidates as you would get more mileage out of the results.

How about typing? Or piano?

The greatest thing to come out of Australia since Paul Hogan. 😂

When my therapist asks me why I have feelings of inadequacy about being a ten fingered piano player.

WOW! so much stroke patients

Nice. Always thought it's a shame humans only have one opposable thumb.

imagine the card tricks with this

That's so silly. Yet so interesting.

GBS Nice 👍

From the moment I understood the weakness of my flesh, it disgusted me. I craved the strength and certainty of steel. I aspired to the purity of the Blessed Machine.

my uncle jim could make that in his garage with a torch and a bud light.... you got soft hands brother.

I want a extra thumb on each one of my hands it would be amazing an I don't know why we were not born with an extra thumb on the opposite side of each hand or bottom of the hand it would help so much. 😊

Meanwhile people like me born without all of the digits on my right hand can't even get help getting a four fingered prosthetic

US: We're working on practical inventions like army Robots, ReUsable rockets 🚀 etc. 👌💪 UK: We have 6th finger 🤦😅
