'Smart Fingertips' Pave Way For Virtual Sensations

samzenpus posted more than 2 years ago | from the let-your-fingers-do-the-virtual-walking dept.

Science 69

sciencehabit writes "Imagine feeling like you're lifting a 50-kilogram weight just by pulling at thin air. That's just one of the possible applications of new 'smart fingertips' created by a team of nanoengineers. The electronic fingers mold to the shape of the hand, and so far the researchers have shown that they can transmit electric signals to the skin. The team hopes to one day incorporate the devices into a smart glove that creates virtual sensations, fooling the brain into feeling everything from texture to temperature."

I'd rather wait for the technology to get some decades of use before I'd even get near it. Just the idea of putting a limb inside a device that would simulate pressure makes me think of Iron Man, you know the part where he's at a hearing and you see the competition's failed tries.

Yeah, that really changed my outlook on a lot of things.

It's actually surprisingly difficult to make haptic pornography with high enough resolution. "Taxels" on the tip of the finger measure ~1mm across, yet it's the complex interactions between them which create precise sensations of touch. Those complex waveforms are what's difficult to analyse and reproduce. Believe me, I've tried...

Anonymous Coward | more than 2 years ago | (#40944305)

Tactile sensation =/= resistance... It's not going to feel like your lifting anything...

Re:ummmmm (1)

fuzzyfuzzyfungus (1223518) | more than 2 years ago | (#40944383)

It would be a bit more invasive; but actuating muscles with external electrical signals isn't exactly science fiction, and I suspect that you could get a surprisingly convincing feeling of resistance if you combined a bit of externally-induced muscle tension with a strong sensation of pressure on the skin surfaces supposedly in contact with the item.

It wouldn't be quite right, since, in absence of an actual weight, you'd need to stimulate the opposing muscle group as well to keep the user's hands from just flying upward wildly, which would lead to a somewhat odd distribution of muscular effort and soreness compared to the real thing; but I suspect that the addition of realistic skin-pressure cues and/or visual overlays could probably fake the user out fairly convincingly for lighter objects.

Re:ummmmm (1)

mister2au (1707664) | more than 2 years ago | (#40944399)

Exactly !

Who lifts 50kg with their finger tips anyway - not even a static 50kg could be simulated. And even if this is expanded to whole-of-hand can it really apply 500N of force ???

Fine motor control for remote applications - whole different story and a fantastic application ...

Re:ummmmm (0)

You support it against rock, not air. You can't simulate it by squeezing the fingertips, because it's obvious to the brain.

I suppose this one is more miniaturized, but "virtual reality" and "haptics" people have been trying this sort of thing for a while, without having yet really come up with a compelling win. Here [google.com] is a 1995 Popular Science article about a device that takes basically the same approach to characterizing what constitutes texture perceived by fingertips (by simulating sliding/bumpiness/resistance/stickiness). Available for only $20,000! And a 1996 textbook [amazon.com] devoted large sections to the topic as well.

Re:isn't this a fairly old idea? (0)

Anonymous Coward | more than 2 years ago | (#40951167)

A related technology is electrovibration. Wikipedia says "the history of electrovibration goes back to 1954." You touch a surface with an insulator, and an alternating current underneath creates a static charge on your skin. As you move your finger over the surface it is pulled into the surface and feels like friction. The charge doesn't go deep enough into your skin to affect your nerves directly.

The article is unclear on what this technology is. It seems like they are running a current through your finger nerves.

When, oh when, will we be able to live in a world where the "nano-ness" of an engineer is no longer noteworthy? Do you really want to live in a world where it is okay to deride someone with comments like "From small minds come small ideas", or "She uses CGS because MKS is too big for her", or "Why are you crying? Got a Planck in your eye?", and the like? Think of the wee children.

Re:Nothing can go wrong with this. (1)

RivenAleem (1590553) | more than 2 years ago | (#40945507)

But if you can transfer the impression of being on fire, without physically injuring the subject, then you go much further with the torture, until, I suspect, the person just goes loo-la.

"What happened to your hand?" "Hackers." (3, Funny)

Havenwar (867124) | more than 2 years ago | (#40945797)

A glove that makes me feel sensations is great and all, but I do hope it comes with some pretty heavy security limitations and so on... Wouldn't want some hacker to get access to my machine and burn my hand, or shock it, or even just cause extremely unpleasant sensations to it as a form of blackmail or just for kicks. Sure, "just take it off"... not so easy if both your hands are spasming because you feel they are stuck into a fire or something.

Re:"What happened to your hand?" "Hackers." (1)

neminem (561346) | more than 2 years ago | (#40946185)

If it were just the sensation, and didn't actually cause your hand to be burned or shocked or whatever... I bet you'd have a new untapped market for that. An... adult market, let's say.

Re:"What happened to your hand?" "Hackers." (1)

Havenwar (867124) | more than 2 years ago | (#40946505)

First off, to the people you are referring to it wouldn't matter if they were actually shocked and burned or whatever. They do that for fun. Secondly, they don't find it fun when it happens to them non-consensually, e.g. because their system was hacked. Which is what this thread is about - the porn thread you'll find higher up.

As for whether it matters if the sensations are caused by the stimuli - no it doesn't. Your body still reacts to pain whether it's real or not. if you perceive you are being shocked or burned, then that's what your body will react to. That's a horrible power to put in the hands of someone with access to your computer.

Re:"What happened to your hand?" "Hackers." (1)

Havenwar (867124) | more than 2 years ago | (#40949663)

I feel that the fact that people modded this funny really proves that this is a valid concern.

Re:"What happened to your hand?" "Hackers." (0)

Anonymous Coward | more than 2 years ago | (#40957673)

While the article is a little bland (a "mild tingling" is what I've gotten when I accidentally touched some exposed circuits... been able to do that for decades), I think if we *could* get to the point of simulating sensations like extreme heat of physical crushing... it presents a scary line of curiosity.

How far can we take it? Could we simulate extreme pain without actually doing damage? Make someone feel like their hand is burning, and now you have a torture device that leaves no (or very little) physical scars (but probably plenty of mental ones).

Just remember - "Fear is the mind killer. Fear is the little death that brings total obliteration." :)

Re:"What happened to your hand?" "Hackers." (1)

Havenwar (867124) | more than 2 years ago | (#40957751)

Well I have to wonder though, at that point we probably have the technology to introduce the mental scarring directly. I.e. to confuse and disorient people with chemicals or certain signals in ways that mean torture is needless. More akin to just hacking the psyche directly rather than brute forcing it, I suppose.
