Intelligent Scalpels Through Touch Technology
DullTrev writes: "The BBC News site is running a story about touch technology. Basically, haptics is the science of incorporating a sense of touch into technology. Scientists at the University of Tokyo have developed a sensor which can feel. So you could have a surgeon operating with a scalpel incorporating this technology, the scalpel could push back against the surgeon when he tries to slice and dice an artery. I'm sure there could be loads of applications for this technology - most uselessly the test these scientists have been doing - stopping cutting a hardboiled egg when you get to the yolk..."

can u dig it??
This will probably be a great leap for telemedicine. Once it's proven that it can be done, what then?
Nobody's explained how this will improve medicine to have a surgeon hundreds of miles away. Why not have them right there?
Finally, my robot sheep will now push back if they are on the edge of a cliff! ;)
According to the article, it tells the boundary between the objects via the varying conductivities. Interesting. Now, unless I'm mistaken - it's been a long time since I've had any electronics education - you can't measure conductance without applying voltage, yes? If so, this seems like it may not be the most healthful thing possible. Granted, we're probably not talking about much voltage, but electricity and people are just not a good combination. We get enough fried enough because of sitting in front of monitors all day - this isn't gonna help.

His basic premise was prophetic as well. Maybe I should go back and read him again.
There is probably a lot of uses for this touch technology in the sex toys industry. The could make certain toys apply the right amounts of pressure to the right places.

Our company works with haptics in surgical *training*, and I must say that this is both more effective and involves fewer regulation issues. Using haptics to simulate a surgical procedure means that surgeons can train to be better - and then they don't need a computer to stop them from killing me. Heck, it even saves pigs.
How could it be useless to test out something like that? I'm sure something like that would come in incredbily handy when it comes to most types of organ surgery. It'd allow you to only cut at a certain depth through tissue so you could avoid doing any serious damage if anything goes wrong. Whats so useless about that?
To the balloon pants!
most uselessly the test these scientists have been doing
Useless tests?
This is an experimental new tool. The scientists are predicting it can be used to detect (say) the membrane surrounding blood vessels, yet these tests are useless?
It would be both foolish and ignorant to test out an EXPERIMENTAL tool that actually MOVES in a surgical life/death environment. What then could be used to test out its detection of slight changes in membrane? Hello? The layer surrounding the yolk would be similiar to the same one you would see in a vessel...
Difference? If the tool screws up with the egg, then you can have scrambled eggs... the result in a person isnt even half as good.
The surgeon is being trained to keep cutting until the knife warns him that the tissue he's about to cut is important.
So if the knife DOESN'T warn him - even for a couple miliseconds, he cuts right through arteries or nerves.
The potential for trouble is enormous.
And unlike VR built from MRI imaging, there's no indication that a failure is in progress until the damage is done.
I sure hope the authors of any software involved, and the designers of any hardware, are VERY good at building a VERY robust product.
I remember a certain radiation therapy machine, which operated in two modes - one with an attenuation shield, one without it. If you typed too fast on the touch-panel control, it would go through the whole cycle normally, but with the shield OUT rather than IN. Killed several patients before they figured out what was happening.
I hear they had done a marvelous faiure analysis on the hardware. But they had assumed the software would be perfect.

IIRC, surgeons practice on eggs because they have the same sort of 'feel' as human internals do.
...Or am I thinking of oranges? They have the same properties as human skin, ISTR.
Anyway - would you rather they test this out on real living tissue (e.g. your heart) or on something which is already dead and gives a similar consistency/texture/feel?
I know which I'd rather they try first.

Yet another crippling bombshell hit the beleaguered people community when last month IDC confirmed that people are accounts for less than a fraction of 1 percent of all servers. Coming on the heels of the latest Netcraft survey which plainly states that people have lost more market share, this news serves to reinforce what we've known all along. people are collapsing in complete disarray, as further exemplified by failing dead last [sysadminmag.com] in the recent Sys Admin comprehensive networking test. You don't need to be a Kreskin [amdest.com] to predict peoples' future. The hand writing is on the wall: people face a bleak future. In fact there won't be any future at all for people are because people are dying. Things are looking very bad for people. As many of us are already aware, people are continuing to lose market share. Red ink flows like a river of blood. FreePeople is the most endangered of them all. Let's keep to the facts and look at the numbers. OpenPeople leader George W. Bush states that there are 7000 users of OpenPeople. How many users of NetPeople are there? Let's see. The number of OpenPeople versus NetPeople posts on Usenet is roughly in ratio of 5 to 1. Therefore there are about 7000/5 = 1400 NetPeople users. People/OS posts on Usenet are
about half of the volume of NetPeople posts. Therefore there are about 700 users of People/OS. A recent article put FreePeople at about 80 percent of the people are market. Therefore there are (7000+1400+700)*4 = 36400 FreePeople users. This is consistent with the number of FreePeople Usenet posts All major surveys show that people are has steadily declined in market share. people are very sick and their long term survival prospects are very dim. If people are to survive at all it will be among OS hobbyist dabblers. people continue to decay. Nothing short of a miracle could save it at this point in time. For all practical purposes, people are dead.

I remember it was the fall of '83 and I was just a struggling writer trying to make it in New Orleans and I had been to visit my parents up in Shreveport and I didn't have much money then so I was trying to conserve what I had and I had left my old beat up chevy and had taken the bus up to see them and now I was on my way back on another bus, all full of my Mom's good southern cooking and my suitcase, which I had tied up with a cord because it was so full, too stuffed with clothes, now starchy clean, that I had left behind on previous visits and food that my mom put in there to make sure I didn't starve in the city, was up in the rack opposite where I was sitting. It was hot, its what they call down there an indian summer and the bus's air conditioning wasn't working and everybody was trying to get their windows open, but you know the way those bus windows work, they are so afraid someone like a kid might fall out, so they just open a tiny couple of inches and you can only get just a whiff a air. But I was just fine, I like the warm southern air and I was happy, besides I had on shorts and a t-shirt and a pair of sandals and I was just starting to read one of those Saroyan novels when the bus made one of its stops, and when it stopped it wasn't any kind of a gentle easy you don't notice it kind of thing, but this driver made a production out it, he had called out every damn little town we had pulled into three or four times, miles before we actually got there and then with hissing of air brakes and a stop so abrupt you had to brace yourself, he would bring that monsterous contraption to a screeching halt. So there was no way you weren't fully aware of each new tiny town bus stop cafe. I think it was right around Shongaloo where we picked up that girl. It had been another production stop and I was alert and watching the new passengers struggle on with all their suitcases and cardboard boxes and maybe a guitar and a jar of jam and then she came up those stairs at the front of the bus holding her little plastic suitcase out in front of her and she looked like a vision of lovliness, a picture of sweetness and gentleness and grace with the smoothest creamiest skin and raven black hair coursing all the way down to her waist. I was sitting about half way back, but I could see those piercing, azure blue eyes all the way from where I was sitting and I could feel my heart just thump right then and my throat tighten just a bit, she was just so darned beautiful. She made it up to the top of the stairs and began looking around like she was trying to find someone she knew glancing from one side to another from the front down the length of the bus and then she looked my way, she looked me right dead in the eyes and with a kind of toss of her head, like she had found an acquaintance, she came down the aisle and stood right by my seat and began to put her suitcase in the rack over the seat and I look up at her and her head was looking up putting up the suitcase with arms upstretched, and I just stared at her amazing form. She had the most beautiful body like something I had seen in magazines or maybe dancing somewhere and she was dressed in one of those summer calico dresses that just seems to cling in all the right places and there was not one part of her that didn't seem wonderfully luscious and succulent, and then she sat right down by me like this was where she was supposed to be. And right then I smelled the most phenomenal fragrance, the most wonderul aroma, it wasn't just a smell it was like a whiff of heaven itself and it filled my nose and my lungs and my head and it was like the most wonderful perfume I had ever known, she radiated it, I wanted to just breathe it in again and again I couldn't get enough. The only smell I could compare it to that I had absolutely gone crazy for before this was the smell of fresh baked bread when ever I had passed by the Mrs. Bairds bakery late at night and they filled the air with that marvelous golden aroma of bread baking in those ovens, I used to stop and just breathe it in and imagine those beautiful loaves and what it would taste like. Of course the bread never tasted that good but oh that smell was the most delightful experience that my sense of smell had ever known until now. And now this little beautiful southern gal who sat down beside me, who picked me to sit down beside, was radiating the perfume from heaven, and it was every bit as wonderful and luscious and delicious as that baking bread but it was sensuous and sexy and I looked and her and breathed her in and I wanted her more than anything in the whole world. And I suddenly realized that I was just staring at her full on and she was looking back at me right into my eyes like this made perfect sense like that was the way people would normally greet each other and so I kind of stammered out some words and I said the only thing I could think of which was, "That is the most amazing perfume you are wearing. What is that?" and she just responded to me slowly like something else was going on in her mind while she looked right into my eyes like she was looking for something, something she could read inside my brain maybe inside my soul. "I'm not wearing any perfume. I jes been workin' outside all mornin'. I guess Im a little sweaty." And my body just trembled, Im serious it trembled, because I knew that I was in the presence of one of God's perfect creations, I knew I was experiencing the real stuff, the manna, the ambrosia, the essence of heaven itself. Oh my goodness, I was smelling her, I was breathing her sweat, her body odor was like the most exciting sensuous perfume any swiss or french chemist working away twelve hours a day in some cramped laboratory with tubes and bottles and bubbling retort condensers could come up in five lifetimes. And her voice triggered something inside me like an old, old memory, maybe like when I was a tiny baby and I heard my mother cooing me to sleep, gently rocking me against her breast in that great big rocking chair, or maybe like some kind of past heavenly existence where only gentle angels talked to me in kind assuring voices, but in any event it was a voice I loved, and I knew and I wanted to hear again and again. I wanted her to just keep talking, i wanted that voice to bathe me with its wonderful dulcent tones. And then...
Since professional brain surgery is rapidly FTL'ing light-years beyond the clumsy incompetence of mere human surgeons, robot neurosurgeons may soon be able to adapt and adopt this exciting new haptic scalpel technology for the next time one of us Transhumanists needs a minor cranial excavation and rearrangement of our precious neural tissue. The Sensorium Module of the Artificial Mind for Cyborgs may make use of the haptic scalpels in the appendages if not hands of robot doctors.
At the risk of seeming to tie in any and all bionics-related Slashdot articles with the 'shrooming Public Domain Artificial Intelligence Project, let a few independent AI Mind URLs now be adduced to stifle the nattering and snickering of Slashdot anklebiters who don't realize that there's a Technological Singularity going on.
The first Mind implementation is in MSIE JavaScript at http://mind.sourceforge.net/ -- an online AI.
A previous attempt at porting Mind.Forth to Visual Basic was http://www.virtualentity.com/mind/vb/ -- Mind.VB (3.Apr.2000).
A more recent port from JavaScript into Mind.JAVA is at http://www.angelfire.com/nf/vision/ai/mjava.html-- (June 2001).
All these artificial Minds blossoming and proliferating across the 'Net may matriculate at various medical schools, earn a Medicinae Doctor degree, and assist or solo at your next brain surgery with the new intelligent scalpel technology. Now, any comments from anonymous cowards ankle-biting at the footsteps of AI progress?
Such technology already is in use to harvest tomatoes. A robot arm can slightly squeeze them and determine the ripeness of a tomato based on the firmness of the tomato. If not ripe, then the tomato is left alone to get some more sun. It's systems like this which can be used to automate farms.
I intend to live forever, so far so good.
Aside from serious apps, I wonder if this could be used for recreational weapons and stage props. A sword that cuts everything but human skin would be peachy keen.
Imagine.. you and your geeky Renaissance friends could suit up and smash away with realistic swords and minimal armor- no more dorky duct tape swords, W00t!
Meaning everyone will have two little needles in a box on their desktop, which they can use to feel the texture of a website? My guess is that successfully bringing haptics to the desktop and making them part of everyday usage will not happen "soon", but will take a great deal more development until the same quality of tactile feedback can be translated to, say, a VR glove, and linked to visuals. Even then, in its initial stages, I see few applications beyond some games and pr0n.
Ceci n'est pas une sig
Hasn't it occured to anyone that if a doctor is so error-prone, constantly nicking arteries of his patients, that he shouldn't be practicing surgery in the first place?
Just what the doctor ordered.. An electric steak-knife. Sorry, gang, but if a surgeon cant handle a scalpel with any degree of competence, you need to find a new surgeon, not a new scalpel.

A good surgeon is a good surgeon because of their ability to sense what is going on inside your body as they cut you apart. If you take away the necessity for them to develop their own sense, only to rely an electronic impulse - well why not just use robots to do the whole dang thing. Modify an automanufacturing welding robot to do surgery, get it done in half the time for 1/4 the cost. Sure sounds good. So what if it kills and maims twice as many people, it's progress and it's profitable. Electronics will never replace the complexity and abilities of the human brain and mind.
what about end user support when this thing blue screens. Talk about a general exception fault ruining your day.
The Mimes claim they own a copywright on typing on things that aren't there and are filing a lawsuit.
They say it's a job security thing.
I attended a presentation by a French team three years ago, in which they had actually used feedback scalpels in the operating room.
The doctor usually stops cutting well before any feedback is felt, but sometimes it goes near the feedback and overrides it, because his visual inspection is better than the PET scan used to determine feedback levels. The feedback is simply a way to tell a doctor "stop, are you sure about what you are doing?".
They also had samples of robots sawing bones, opening crania and doing, get this, prostate inspections. By the end of the presentation all the males in the room had placed our hands instinctively covering that sensitive area.
Come on those of you who think the onlu use of this is for porn. It looks like a great enabler for those with resricted or total loss of vision. Wouldn't it be great to be able to feel the data in your spreadsheet or feel how your network is performing. However I can't be sure from the article if the breakthrough is the sensor technology or the bio feedback mechinism. slashnik
I'm really skeptical about the possibility of really effective tele-surgery. I'm not a surgeon, I'm an architect. I have a fair amount of experience building models, and I can't imagine building even a so-so cardboard and balsa model with telemedicine equipment. You would think that it's easier to cut and assemble cardboard than to suture an artery. Haptics are critical in getting there, but even in basic modelbuilding there's an astounding amount of very subtle feedback and knife control involved. I have to say, though, that the 'stop and the yolk' work makes a lot of sense as a test for this system.
Or better yet, sensors in my the seat of my pants so I can tell when people are checking out my butt...
It'd be interesting to see this technology applied to the war industry.
---If you can't trust a nerd, who can you trust?
I swear this came up already in the discussions about SIGGRAPH 2001. The Researchers who came up with this were showing it off. In response to the earlyy post about electrical currents and such, it doesn't have to be an electrical current feedback, it can use any kind of feedback, optical, density, etc. Basically what this device does is it senses the boundary line between two different substances (i.e. water and oil, white of an egg and its yolk...) and gives them a very strong tactile feedback to keep them from pushing through - however one can override the device and still push through.
I got to try it at SIGGRAPH. As an example they had a small clear tank filled with water and something heavier beneath (dunno what it was...obviously nontoxic though). They handed you a pen to stick into the mixture and try as you like there was no way you could determine where one liquid stopped and the next began simply by touch (the liquids were different colors). Next they let you try with the haptic device. A clear plastic or glass wand the same size as the pen which was connected to a robotic arm. Every time the wand touched the surface of the lower liquid, the robotic arm would kick in and keep you from penetrating it with a fairly strong force that would take some serious concious effort to overcome. Basically the device let you literally feel the line of difference between the liquids, which you would otherwise never be able to dectect by touch. In fact, just to prove how well it worked, they would from time to time bump or stir the tank so that there would be visible ripples in the intersection of the two liquids. The haptic device still worked great at letting you feel the bumps and valleys created. The video/slideshow on the wall behind the display showed the hard boiled egg example among other things. The person wielding the scalpel was able in a single quick cut (less than 20 seconds) cut the white off the yolk without cutting the yolk at all. This could allow doctors to cut through a layer of skin or tissue without cutting what was underneath. It doesn't have to be recalibrated for each and every set of materials used, just the one that it is pentrating. It detects differences in properties (such as conductivity) and won't let you penetrate anything but what you set it to allow you to pentrate.
I'm out of my mind right now, but feel free to leave a message.....
Attending one of the Universities connected and researching the Interent 2, I can safely say I have heard a lot about it. Achieving the kinds of bandwith and latency required for such things as remote surgery is exactly the goals of the researchers putting their time into this project.
Not only that, but there are other opportunities in "remote" surgery that this technology opens up. What if the specialist could see the surgery and communicate to a general surgeon on the patient's end. If the general surgeon used this haptic scalpel, it could not only enable him to better work in areas of the body he is not as familiar with, but the remote specialist would also recieve a lot more data to diagnose the problem and give the general surgeon instructions. If there are bumps on a heart that the general surgeon doesn't know should or should not be there, a haptic sensor connected to a 3D input device could allow the general surgeon to produce an image map showing the bumps, and the remote specialist could get a 3D image or even better, which could be fed back into another haptic device, allowing the specialist to feel the heart without even putting his hands in the patient's chest.

There are some commercial companies who have been working in this area for several years.
Most notably Reachin and SensAble.

They used a LS in Fiber with a DIRECT CONNECTION.
So only repeaters.
Lag time is under 50ms.
So with the haptic interface is better, but today LAG time is not the proble. You only need one hell of a link, but those exist for some very rich people 8)

I purchased one of these Fu-Fme model V units a while back. I haven't really had much luck finding others with the unit so I spend a lot of my time f**king the software girl that comes with the system. Also, at $499.95US it is a fairly expensive device.
If you are using the pre-1.4 version of the software, make sure you get the 2.1 patch. Early on I had a bit of bad luck and ended up with very minor burns to parts of my pecker.
Anyone else here have experiences, good or bad, with the FuFme unit?
is just the same as any other sense technology. recorded sound gave us the ability to reproduce sound far away in time and space from it's origin. when touch is on an equal footing to this, it will be so commonplace, you won't think of it any more than a photograph, or tape recording.
