Artificial Vision for the Blind
castanaveras writes "Canadian doctors implanted an artificial eye into a blind man - it performs well enough for him to be able to drive (admittedly in an empty parking lot)." We've done lots of previous stories about bionic eyes.
Bionic eyes!! Ya!!!

Now that they can replace your glass eye with one that actually lets you see, I guess my novelty glass eyes won't do so well... It would have been nice to see them go into production, the magic 8 ball eye, the screen saver eye, and the flashing 12:00 eye... I wonder how long it will be before someone works out how to advirtise directly to your brain by hacking your eyes... gives whole new meaning to feed my eyes doesn't it.

Actually it was done in Portugal to get around local regulations...
They weren't Canadian doctors. They were doctors from the university of St. Louis doing the procedure on a Canadian man.

Hrm... they omitted that they eye sends back photographs, streaming video, and other data to Echelon monitoring facilities.
They also failed to mention the artificial eye's laser beam and the mass destruction capabilities.

In order to go to sleep, does the man needs to turn his artificial eye "off"?
"Jens and the other patients wear special sunglasses fitted with a miniature TV camera. The equipment attaches by cable to a tiny fire hydrant-like device implanted in the skull that connects to two electrodes on the surface of the part of the brain that controls sight.
In other words it connects to two electrodes on the surface of the visual cortex. Which is in the back of your skull. They have NOT implanted an artificial eye.
I just love these stories. It is a marvel of biotech and engineering. Maybe engineers have trouble picking up girls. Every day, in every other way, they make bigger and bigger difference.
These artificial eyes have lots of potential users that are currently employed as baseball umpires...
So if creativity was your only limitation, what would the ultimate artificial eyeball be capable of?
I assume it would have huge amounts of optical zoom capability. Would it also have some sort of CCD showing so that you could change your eye "style" on demand?
Maybe it could have a little hole in the middle of it setup to squirt "eye fluid" on people you don't like!

There were no actual canadian doctors involved, only a canadian patient... But Canadians are also developping a visual implant similar to the one cited in the article... You can find more info here, or here (in french). (the last article is from 2001... wonder what is happening right now...)

When Can I Get My Third Eye Installed?
Jorde LaForge, eh? Well... I'd say this probably works more like the borg. All the patient needs is a little laser beam coming out of the side of camera.
I knew an eminent blind person and researcher at a university who was often called upon to comment on or even to test artificial vision equipment being developed at the university. His usual response was that nothing beats a good guide dog. This demoralised some folks at the university who were trying to develop and get funding for a guide robot for blind people. That latter project made the headlines when it was the subject of a hilarious cartoon in a BMVA Newsletter a few years ago entitled "Guide Dogs for Blind Robots" (no online copy found).

So this is being taken from video cameras - what about connecting to some modified frame buffer so it could allow people to read text/view the web.
I guess there is a lot of scope for pre-processing to work around whatever limitations these devices have.
Add some sensing for the muscles around the eye and then you could do a large virtual display surface.
Oh this is not really a big deal. Star Trek showed us years ago that you could make a blinde man see just by putting a hair-clip over the front of his face.

Don't bring up the space arm debacle. Oops...
I really don't think this will be too useful except for the completely blind.
Even then there are other factors, such as learning how to see when you didn't see before.
On a side not, they said the same thing about Coucher implants and those are marginally useful only (they are limited in what they can do).
Applying a current across the visual cortex creates patterns.
Ho hum.
...this is actually nothing particularly special, since all the technologies are relatively well-known (among the right circles), and mostly invented by Dr. Steve Mann of the University of Toronto. According to Steve, what the patient actually perceives is more akin to contrast resolution, rather than anything that the visually unimpaired would call "sight".
What is perhaps more interesting, and more widely useful is the Eyetap technology itself. Essentially, Eyetap uses the camera and wearble computer to drive a small laser that mediates reality directly into the eye. For people who are not blind, but profoundly visually impaired, this technology may be a godsend.
Beam me up, Geordi LaForge!
I think the most important part of the article was the bit about not giving false hopes to the many folks who have been blind since birth. Since they will not have developed the ability to interpret stimulii from that part of their brain, this device will do them no good.
Properly marketed though, this device could do a lot for thos who have lost their sight from disease or accident.
Hopefully as the technology develops and is refined, they will also look into researching ways for those blind from birth to use this technology as well.
I wonder what will happen when bionic eys (ears, limbs, memory) are better than your perfectly functioning ones. Will people upgrade themselves like they do now with implants and plastic surgery? It's closer to reality with these great technological advances, but are we ready for it in our culture?
When I was yonger I used to wonder whether I had the choice of losing sight or hearing which would I chose. Sight is so important to us. Yet to lose hearing would be to sacrifice music, which is my main pursuit outside of work. Also, it would be less of a step down for me to lose sight than for many people. I was born with a deformed left eye. A strip down the middle of the retina is missing, and there's a separate, more complicated problem I've never bothered to learn about as well. I used to wear plastic-, then glass-eyes to mask it. The plastic ones were made oversized and have stretched the skin around the socket, and it became painful, but that just gave me the excuse I needed to give up wearing them altogethre. I feel proud to have a problem that isn't and not cover it up, and rarely think about it, and have friends and family completely forget about it.
It's better to be born that way than to lose an eye for several reasons. Obviously, the pain and anguish of losing an eye. Also the need for people in that situation to redevelop their coordination. The only disadvantage is that if you don't develop parts of your sight while you are young - like me, you don't develop it at all. There will be a limit to which the brains of people given sight mid-life will be able to use them. Stereoscopic vision will be right out (even people with squints that come good can have problems with this, like my father), and they will never develop the coordination that somebody with childhood experience can.
Still, developments like those in this story give you a warm feeling about the positive power of our scientific endeavours, and the benefits of progress.
My former rowing coach is a dentist. Somehow years ago we got to talking about his work, and gross medical professions. Consensus among the squad was that optic surgerey was the right up there with the most squeemish of them, and he commented that in a way he wished he'd put his energy into that field rather than his own. When we asked why he responded that for the same amount of work you get to fix people's sight, and that that's one of the finest gifts you can give somebody.

Believe with me, my saplings.
There's been a long-recognized phenomenon discovered among people who have sight restored after long periods of blindness: Motivation Crisis
http://psych.wisc.edu/vision/courses/recovery.htm
http://216.239.35.100/search?q=cache:ZD8gWmH2aEYC
Notes on this phenomenon go back to at least 1771, with the publishing of the book "L'Aveugle Qui Refiise deVoir." By 1932, there was a book "Space and Sight" that concluded that "every newly sighted adult sooner or later comes to a 'motivation crisis', and that not every patient gets through it." Fortunately for this guy though, this problem seems to be more linked to people who lost their sight early, and then regained it much later, having to radically change their lives down to the tiniest mannerisms. It might have something to do with the time limitation they are putting on him, and the scientists choice of Jans, for his positive attitude.
Definetly an interesting topic on human psychology though. Hopefully with future inventions along this line, no one will be forceably blind long enough for such depression to occur along these lines. It makes one wonder though - will more distant technology create a new sort of "Motivation Crisis" in us if perception enchancements become widely available and used.

I wonder how they have solved the problem of decomposition - the body's immune system is a powerful entity. Implant a silicon chip and the body will attack it and erode it. Implant it in a glass capsule and then how to make the electrical connections?
These things have been reported several times in the past but each time, it degrades within months and typically doesn't last even 6 months in the body.
So how "permanent" is this artificial eye? That is the question everyone wants answered. Does it require lots of external hardware to operate (as some older experiements have done). What kind of power source is required?
-- The universe began. Life started on a billion worlds...
-- Except on one where stupidity was there first.
The problem with advances like these is that everyone looks at them and thinks, "Oh, great stuff! Before long, we'll be able to let all the blind people see."
Which may happen... or may not. But in the meantime, people see it as a little less important to make sure that the world is accessible to those who are disabled, when they're convinced that a 'cure' is right around the corner.
Cochlear implants and bionic eyes and so on and so forth... they all sound terrific. And there will be people helped by these advances. Just don't let yourselves get caught expecting too much of them. And remember, programmers and designers out there, to make sure that your projects are accessible. Text needs to be readable by a screen-reader. Audio should have available captions. All that jazz.
Mod parent all the fucking way up! You speak the truth, sucka!
I saw a documentary of a case study of this once. Apparently this kid lost his sight and hearing at a young age.
He later became pinball champion of the world, but upon regaining his sight and hearing, he led a cult until they revolted against him, and he lost everything.
I forget what the name of the documentary was.
I've had enough abrasive sigs. Kittens are cute and fuzzy.
Don't get me wrong, I'm very impressed by this device, and I hope it works out.
However, the visual cortex is not the end all-all be-all of visual information in the brain. Visual information on the way to this cortex is first passed through other areas of the brain, such as the Lateral Geniculate Nucleus, which process the information, and also allow it to interact with other brain areas.
Based on my knowledge of the intricate, piecemeal nature of brain design, these pre-processing areas are probably involved in some fairly important low-level, reflexive aspects of vision. Bypassing them may restore the conscious aspects of vision and allow a great deal of function, but will miss out on some other aspects of vision that we are not consciously aware of.
Repairing the optic nerve is the only way to get real vision.
But that's step #1000, kudos to these pioneers for having the courage and ability to do step #10.
AOL will probably market "AOL Eyes'. At only 1.5x the cost, you get "special product offers" exclusively available to AOL Eyes users. Each eye will have a seperate, full screen window inside of an mdi interface with no tasklist. It will crash whenever you turn your head too fast, and it will take your brain down with it.

I hate it how this article tells you how people can only see to a limited degree, but it doesn't go on to tell you how limited. Like what is the resolution behind these puppies? Refresh rate? Even better why don't they actually tell us about the technology behind them. How they work. That would be way more useful than the knowledge that somebody just got one.

It appears that this device sees visual specectrum waves, but couldn't it work just as well with other frequencies? The hard part was hooking it up to the guy's brain, and it appears they got that to work. It shouldn't be any issue at all to substitute a more sophisticated camera. Doing so could allow them to make a spread spectrum version, that would allow the "blind" guy to see visual waves usually, and infrared during the night/fog/etc. They could even see through buildings.

Give a big enough empty parking lot and a blind man can drive WITHOUT an operation!
Remember: during development, the optic nerve is part of the brain itself, and the amount of circuitry inside the brain proper which is tuned for visual processing is immense. Getting individual pixels into the brain -- the current accomplishment -- is of course a technical acheivement. But processing it like sighted people do is a challenge of similar magnitude to brain transplants. On the other hand, it might be possible for those who've lost their vision. (But those blind since birth is another story entirely.)
"The device doesn't work for all types of blindness. People who were blind from birth, or who lost their vision in childhood are not expected to benefit because their visual cortexes would not have developed fully, Smith said."
Suppose this wasn't the case, and you could give sight to somebody who had never seen before. Would their brains be able to interpret the flow of new information?

on a side note (at the risk of being rated down), is anyone in the slashdot community actively and consciously creating accessible websites? at this point in artificial vision technology, no one has yet to create a widely accepted, usable solution. there are too many diseases, too many causes of blindness to deal with to see a fix-all solution come about... so the best solution is to either ensure that a site is accessible, or design an accessible alternative site. you would be surprised at the number of blind people who are online these days. my little brothers and my father are always complaining that my mother is using up their broadband bandwidth at home with her usage.
at any rate, it's something to consider.
We use to clone cyborgs here, in Canada. otherwise it would be difficult to use all this cold space, you know :)
I'm always on the look out for news about eye replacements and chips. As a person who was born with the condition "acromatopsia" I desire to have complete vision. However as I read more about these devices it seems nearly impossible that I'll ever be able to see properly due to the fact I was born with my impairment.
To give a bit of background on my condition, acromatopsia is a mutation of the rods and cones of the retina so images that pass properly through the pupil become garbled or don't pass through the retina at all. This is most often found as a latent gentic trait passed down from residents of a certain island (detailed in the book Island of the Blind) whose eyes have developed differently. Visual problems range due to the amount of improperly formed or non-existent rods and cones. I myself can see but I am near sighted and can only see about two arms lengths away from my face before things become too blurry to discern. I see all in greys (not the "classic" colourblindness) and am super-sensitive to light. This is why "acromatopsia" is often called "night vision" because photophobia is a common symptom and actually helps to make things visible at night.
What concerns me most is if the cortexes of my eyes are developed enough to use these new technologies. I can see if only up close but due to the extreme photophobia and lack of colour vision my cortexes may not be suited for an upgrade. It might be like trying to connect an Apple IIe to an Athlon if you get my drift. Anyone know anything about this? As both a programmer and an artist it's really hard to work when I can't see well, can't tell colour, and have to wear creepy black shades because otherwise I'd be running around screaming "IT BURNS! IT BURNS!".
Righty-o.
Starkle, starkle, little twink.
You know, this has got to be one of the most idiotic posts that I have ever read in my entire life. By any reasonable measure, being blind or deaf or crippled (yes--*crippled* you moron, not "differently-abled" or whatever bullshit PC metaphor you want to use) is a deficit. A lack. Most people recognize this and are fighting to correct these deficiencies. This is a good thing, not "genocide" against a "culture."
BTw, according to statisics most ppl who were born blind wouldnt want the 5th sesnes artificially implanted into them.
Hey, nobody if forcing these Luddites to accept the artificial implants. If they want to remain F'd up all their lives then that's their prerogative. Meanwhile those who want to be cured of their illnesses--and those of use who want new eyes that can give us infrared and/or telescopic sight, for example, or greater hearing ability--should be allowed to receive these gifts without a bunch of Luddite PC fanatics getting in the way.

The very bizarre French movie "Cité des Enfants Perdus" ("City of the Lost Children") has a large group of characters who are blind and who have their vision restored by... (drumroll)... head-mounted cameras that plug into connectors attached to the visual cortex. Well, I assume it's the visual cortex, it plugs into the head in any case and the movie doesn't go into anal-retentive detail or anything. The single lens means they only have monocular vision, and the (presumably) low quality of the whole piece of kit means that the parts of the movie shown from their points of view are tinted green and have scanlines and a lot of background noise. This lets them see well enough to fulfill their task, though: kidnapping children so that a twisted, genetically-engineered genius can steal their dreams. (I told you it was a strange movie!) In one of the most psychologically horrifying things shown in the movie, one blind guy goes insane and starts choking a blind comrade to death... after switching the wire connections so that the guy getting choked gets to watch himself as he dies. Pleasant, eh? The movie is quite good, though. Absolutely insane, but very good, plus it had this whole bionic eye idea back in 1995. >:
Oh cruel fate, to be thusly boned! Ask not for whom the bone bones; it bones for thee. -Bender
John Raymond Hope, one of the country's leading hurricane forecasters, died today of complications related to heart surgery. He was 83 years old.
For nearly 20 years, The Weather Channel viewers turned to Hope for information and guidance when tropical weather threatened their homes. He joined The Weather Channel in 1982 as the Tropical Coordinator and an On-Camera Meteorologist, becoming a key source of information for U.S. coastal residents during hurricane seasons.
He was cited as the "voice of reason" when broadcasting on The Weather Channel, and weather experts often acknowledged Hope as "the man America watches" when hurricanes approached the United States.
Hope's expertise in tropical weather reaches back to 1968, when he joined the National Hurricane Center and quickly rose to the position of Senior Hurricane Specialist.
But, Hope's devotion to meteorology began long before he shared his skills with hurricane experts in Miami and colleagues at The Weather Channel.
John Hope's legacy
John Hope leaves a lasting influence on weather. Read about some of his contributions in these places on weather.com:
Message boards
Hurricanes: The eye of the Storm
Storms of the Century
Tropical Update
The Weather Channel's 20th anniversary
Hope was born on May 14, 1919. He was the second of five children raised on a dairy farm in Stowell, Pa. He attended grammar school in a one-room classroom that was often reached by a long walk through the woods in the snow.
Hope was a struggling high school student in Wyalusing and Meshoppen, Pa., following his mother's death in 1934. He worked at a local A&P grocery store following high school graduation in 1936.
Hope joined the Army Air Corps in 1941, and served for four years. His weather career began while he was in the service, working as a flight navigator. Like many in his generation, Mr. Hope returned to the United States following the war with a new sense of purpose.
He attended the University of Illinois, where he was elected to Phi Beta Kappa and majored in mathematics. He then earned a master's degree in meteorology from the University of Illinois.
While attending the University of Illinois, Hope met Bernice La Pira, to whom he was married for 55 years.
Hope began his career in the United States Weather Bureau in 1949 as a district forecaster in Memphis, Tenn., where he worked for nearly 13 years. He was deemed to have the right stuff by the Spaceflight Meteorology Group in 1962, joining the organization in Miami for the John Glenn launch.
In 1968, Hope moved to the National Hurricane Center in Miami.
Over just three decades, Hope went from releasing and tracking weather balloons outside the old Memphis Airport Terminal, to working on manned space flights to the moon and programming some of the then largest computers in the world.
Along with National Hurricane Center colleague, Charlie Neumann, Hope wrote a program that allowed Third World countries that lacked mass media infrastructure to alert coastal populations in advance of the possibility of a typhoon or hurricane making landfall.
Hope earned international recognition for this technical work. He learned from visiting Chinese scientists that he and Neumann were very well known and appreciated in scientific circles in China.
Hope's enthusiasm for weather extended to young people in 2000, when a college scholarship was established in his name by The Weather Channel. The scholarship is perpetually endowed by The Weather Channel and administered by the American Meteorological Society.
Hope's many honors included the U.S. Department of Commerce Silver Medal, the National Hurricane Conference Media Award and The Neil Frank Award from the National Hurricane Conference. He was a fellow of the American Meteorological Society. Hope wrote about weather for a variety of publications and journals and lectured around the world.
Hope semi-retired from The Weather Channel in 1997, when heart problems sidelined him. After successful surgeries, his health improved to the extent that he was able to participate in hurricane seasons from 1998 through 2001.
When asked about retirement, Hope would smile and acknowledge "You might wonder... but I can only say I love my work."
He said there was "a certain satisfaction at my age, of being able to produce and be wanted by my employer."
In a 1997 interview published by his hometown paper, The Rocket Courier of Wyalusing, Pa., Hope said, "If my legacy can be that I have made a contribution to this nation being better prepared to cope with the devastation wrought by hurricanes, and to have helped in the success of my company, I am content."
Hope is survived by his wife, Bernice; his daughter Camille L. Hope of Macon, Georgia; sons James C. Hope of Lilburn, Georgia; Dr. Thomas D. Hope of Macon, Georgia; and Joseph R. Hope of Atlanta, Georgia; his brother, Leonard Hope of Dalton, Georgia; and six grandchildren.

How long before we see "regain your power of vision in 30 days or less" or similar spams?
I think caution wise over this information. As a visual neuroscientist, I am quite sceptical about the 'direct' excitation of cortex (others have suggested this bit has been solved - this work is FAR FAR from it...) For a start, primary visual cortex is modular, with one region of visual space (hypercolumn) having multiple spatially dispaced representations of orientation (and eye dominance). Each module is tiny, and each module has lateral connections to other modules (both those close and others further, over several millimeters). So you could probably only get unoriented 'blobs'of light for each location in the world (especially because cortical circuitry may enhance orientation tuning as well through subtle increases and decreases of neuron responses). Orientation is considered one of the foundations of 'constructing' a clear perception of the world around us. If you wanted colour, this would be even more complex, because there is no clear surface togography for colour. One feature that may be viable is 3D depth because eye 'modules' are larger than orientation modules and thus could be differentially stimulated to generate crude disparity (?). Not having fully read all of this work at its source it is difficult to be definitive, but I think they can get nothing more than general broad phoneme responses. That is far away from the rich visual world most of us experience. Oh, and multiply the complexity of the scheme i've sketched for the visual cortex several fold as there are many features i've left out / we don't know about yet
Excellent timing, too; just moments ago, a cat tried to claw my eyes out.
Would you knock it off with the Sanrio conspiracy theories already?
What is that? Something that squirts high-pressure water around in his brain? That can't be good.
