Applause For The SmartHand: Human-machine Interface Is Essential Link In Groundbreaking Prosthetic Hand
[www.sciencedaily.com]

ScienceDaily (Nov. 5, 2009) — In one sense, our hands define our humanity. Our opposable thumbs and our hands' unique structure allow us to write, paint, and play the piano. Those who lose their hands as a result of accident, conflict or disease often feel they've lost more than mere utility.

A new invention from Tel Aviv University researchers may change that. Prof. Yosi Shacham-Diamand of TAU's Department of Engineering, working with a team of European Union scientists, has successfully wired a state-of-the-art artificial hand to existing nerve endings in the stump of a severed arm. The device, called "SmartHand," resembles -- in function, sensitivity and appearance -- a real hand.

Robin af Ekenstam of Sweden, the project's first human subject, has not only been able to complete extremely complicated tasks like eating and writing, he reports he is also able to "feel" his fingers once again.

In short, Prof. Shacham-Diamand and his team have seamlessly rewired Ekenstam's mind to his SmartHand.

Linking mind and machine

Prof. Shacham-Diamand's contribution to the project, on which TAU collaborated with Sweden's Lund University, is the interface between the body's nerves and the device's electronics. "Perfectly good nerve endings remain at the stem of a severed limb," the researcher says. "Our team is building the interface between the device and the nerves in the arm, connecting cognitive neuroscience with state-of-the-art information technologies."

Prof. Shacham-Diamand runs one of the top labs in the world for nano-bio-interfacing science: the Department of Electrical Engineering -- Physical Electronics Lab under the Bernard L. Schwartz Chair for Nano-scale Information Technologies. "Our challenge," remarks Prof. Shacham-Diamand, "was to make an electrode that was not only flexible, but could be implanted in the human body and function properly for at least 20 years."

The artificial SmartHand, built by a team of top European Union scientists, will belong to Ekenstam, the test subject, as long as he wishes. "After only a few training sessions, he is operating the artificial hand as though it's his own," says Prof. Shacham-Diamand. "We've built in tactile sensors too, so the information transfer goes two ways. These allow Ekenstam to do difficult tasks like eating and writing."

Complexity of a challenging magnitude

Ekenstam told a television interviewer, "I am using muscles which I haven't used for years. I grab something hard, and then I can feel it in the fingertips, which is strange, as I don't have them anymore. It's amazing."

This particular multi-million dollar project focused on hands, but the TAU/EU team could also have built bionic legs to be wired to the brain. The team first chose to build a hand, however, because of its unique challenges. "The fingers in the hand are the most complex appendages we have," Prof. Shacham-Diamand observes. "The brain needs to synchronise the movement of each digit in a very complicated way."

With the help of the TAU team, the SmartHand project was able to integrate recent advances in today's "intelligent" prosthetic hands with all the basic features of a flesh-and-blood hand. Four electric motors and 40 sensors are activated when the SmartHand touches an object, not only replicating the movement of a human hand, but also providing the wearer with a sensation of feeling and touch.

While the prototype looks very "bionic" now, in the future SmartHand scientists plan to equip it with artificial skin that will give the brain even more tactile feedback. The researchers will also study amputees equipped with the SmartHand to understand how to improve the device over time.

The SmartHand project is funded by the E.U. Sixth Framework Programme. TAU's SmartHand partners include ARTS Lab, Scuola Superiore Sant'Anna (Italy), Aalborg University (Denmark), Tyndall Institute (Ireland), Össur (Iceland) and SciTech Link HB (Sweden).

One step closer to the Bionic Woman!

Kidding. This is a good thing. This is the kind of thing technology SHOULD be used for: helping the limbless touch again. This is exciting stuff.

Finally some good news!

They're also working on bionic eyes - where people who are blind from retinal diseases will have a chip implanted in the back of their eye which transmits the signals directly to the optic nerve. I've seen articles in the last year about them having working prototypes in people but at this time the resolution is only about 6 pixels by 6 pixels. But - for someone who has never had sight their entire life - they can actually see dark and light regions in front of them now for the first time ever.

With the exponential growth in technology and the constant miniaturization, it's just a matter of time until something with 640 X 480 pixels and then the resolution of a 6 megapixel or greater camera can be implanted and hooked up directly to the optic nerves in each eye.

Personally I'd love to have my vision bionically enhanced far beyond what a human normally sees, not resolution-wise, but rather being able to see infrared, ultraviolet, or other spectrums like gamma-ray at will, just so I could see the world in new (and potentially very useful) ways. Or, being able to link up my vision chip with a feed from Google Earth to see what's around the bend or a few blocks away, like a built-in GPS system.

This thread hasn't gotten enough recognition. This is incredible.

In terms of sight and touch, this could easily, given the technology allow people who have lost these senses to not only have the chance to have them again but possibly better and stronger.

I could see down the road people giving up their original senses for something better and replaceable/upgradable.

It's amazing.

Yeah but seriously!!

but that won't be for while after my death, i think this is insane. i'm all for this kind of stuff. 100%!

That's a cool thought. makes me think, where is the line? if you upgraded 95% of your human components to bionic parts, would you still be human?!

I've always drooled over the idea of being able to insert another set of lenses into the eyes, allowing for zoom vision.

It's hard enough to define human as it is. Other simians can also use symbols to communicate. What about people born unrecognizably deformed or those with genetic abnormalities like Down's syndrome where their number of chromosomes doesn't match up with what is defined as a normal human? Where's the dividing line between a mutated human and one that's so different it can't be classified as human at all, despite being descended from two humans. Who decides that line between what is or isn't human, and what gives them the right to choose that line? I don't think we can really boil down to being a mammal with opposable thumbs. To many the mind is as - or more - important than the body in defining what is human. When you start looking at all the exceptions, both mental and physical, to our general idea of what is human, there is a huge gray area indeed, even without technological enhancements.

It used to be that defining what species a mammal belonged to involved two biological examples of the species being able to create fertile offspring. Technology changes that as it allows the creation of radically different new lifeforms without biological reproduction whatsoever. The rules need to be rewritten or discarded as biological lifeforms and cells are now at the point of truly merging seamlessly with technology.

I just say: who cares if the lifeform is human or not? If it's equal or better in capabilities and is more likely to survive as a result, great. Why should we get in the way of the evolution of something better? Just imagine if some creature way back when had arbitrarily decided that human beings were "too evolved, too smart, or too dextrous" 1 million years ago and actively prevented our species from developing, or outright exterminated it?

Let's see what happens, just like we had our chance.

"Normal" is a setting on a washing machine and nothing more.

i'm 100% behind the use of bionic superparts.

I'm not actually sure that simians do use symbols as we do, they use sequences of 'signals' that are communication tools, which does not mean they perceive environment through a conceptual system (which is our condition of beings seperated from "material" real world by reflexive consciousness), neither it could mean they own a language that can be shifted from it's appropriateness to reality for poetic purposes.

But in anyway these are only 'clues' of what seperates us from animals, but if we found our definition of humanity on the constancy of a subjective point of view through time and the ability of a metaphysical thinking, you can not (that was Descartes's statement) tell that anybody else but you is actually human, so we hit a metaphysical wall.


Then, in my opinion, we can not consider the 'line' this way. The only thing I could tell, considering that body is just a tool used the mind/consciousness couple for experiencing environement, making bionic improvement on our bodies does not change anything to our humanity, it's just like having a faster car (well, if we make the statemen that this "mind/consciousness" couple has to have a physical relation with brain, there's indeed an issue with modifying brain... but this statement is impossible to objectify... think that in animism, a soul does not need a brain) . I think there's an issue with the goals we pursue in our lives. When we will have become just technical extension of the 'machine', conceived as a search of pure efficiency, then we will not be humans any more. But that could happen without bionicalize our bodies...

I think the right and human use of technology is the never-ending pursuit of what one could call a "infinite finality". For exemple, art, or knowledge, or a greater good.
I want a technology that leads us to infinity and human exploits without any "performance-cost ratio".

And the best example of that is the exploration of infinite outerspace. This would be a great purpose for Human body improvement, and technological advance in general. We are in a deep lack of dream and human pride, we nearly resignated ourselves to rust in this old planet, trying to fit an always-smaller house with any "sustainable developpement" system... (which could be considered as some kind of autopoietic machine plunging us in an eternal and dishumanizing present, indeed lead by a "performance-cost ratio" logic)

I would not say it this way. I apply to darwinism, in any extend concerning the evolution of matter organized as animal 'life-form', but in my opinion it's indeed the definition of life that causes problem. What's the difference between an animal's life, a plant's life and another auto-poietic system such as the climatic system ? Maybe nothing, that's matter in movement. If you consider what you can objectify of a man, what reason can positively deal with... is a body, an animal.
But where darwinism fails, is defining what's a subject, what's the human subject that has an experience of matter. I would say a Human is not his body, because in an immanency state of total and direct being, there cannot be any experience, because there can not be any subject as a one an only center of the universe he experiences through time. That's why everyone from his own point of view is human, he his fundamentaly different, not only from animal, but from any from of matter in movement (including other "human bodies", that's why recognizing the other as human is an effort on reason).
Since the subject actually makes the universe exist trough his point of view, he subjectively gives an existence to wholes of matter, and paradoxically, to humans as well as to anything. So considering this way of seeing things, you can say that there's no life, conceived as existence, except in Human, as well as you can say that Human is the origin of any life-form which he determines. But in anyway, the conclusion is that there's no life if there's no human, and there was no life before there was any human, and since Humanity takes place in a material shell, there's to different 'time-lines' for the existence of the universe.

Because Human is not matter in movement and not abiding to darwinism, technology can not, I think, being considered as an adaptation strategy. It has to be something else, it's the way we experience and we have an action on matter, and it's the way through achievements that are not related to any natural necessity.

This thread is full of complete awesomeness. I'm all for Prag's idea of having nightvision/ultra violet/etc.....having a brain camera would rock as well!!
