| A bionic eye implant that could help restore the sight of millions of blind people could be available to patients within two years. US researchers have been given the go-ahead to implant the prototype device in 50 to 75 patients. The Argus II system uses a spectacle-mounted camera to feed visual information to electrodes in the eye.
Patients who tested less-advanced versions of the retinal implant were able to see light, shapes and movement. "What we are trying to do is take real-time images from a camera and convert them into tiny electrical pulses that would jump-start the otherwise blind eye and allow patients to see," said Professor Mark Humayan from the University of California. Wireless vision Retinal implants are able to partially able to restore the vision of people with particular forms of blindness caused by diseases such as macular degeneration or retinitis pigmentosa. About 1.5 million people worldwide have retinitis pigmentosa, and one in 10 people over the age of 55 have age-related macular degeneration. Both diseases cause the retinal cells which process light at the back of the eye to gradually die. The new devices work by implanting an array of tiny electrodes into the back of the retina. A camera is used to capture pictures, and a processing unit, about the size of a small handheld computer and worn on a belt, converts the visual information into electrical signals.
These are then wirelessly sent to a receiver just under the surface of the skin, which in turn feeds them to the electrodes. The whole process happens in real time. Growing dots First-generation, low-resolution devices have already been fitted to six patients. "The longest device has been in for five years," said Professor Humayan. "It's amazing, even with 16 pixels, or electrodes, how much our first six subjects have been able to do." Terry Byland, 58, from California was fitted with an implant in 2004 after going blind with retinitis pigmentosa in 1993. "At the beginning, it was like seeing assembled dots - now it's much more than that," he said.
"When I am walking along the street I can avoid low-hanging branches - I can see the edges of the branches." Mr Byland is also able to make out other shapes. "I can't recognise faces, but I can see them like a dark shadow," he said. Brain change The new implant has a higher resolution than the earlier devices, with 60 electrodes. It is also a lot smaller, about one square millimetre, which reduces the amount of surgery that needs to be done to implant the device. The technology has now been given the go-ahead by the US Food and Drug Administration to be used in an exploratory patient trial. This will take place at five centres across America over two years, with 50-75 patients aged over 50.
If successful, the device could be commercialised soon after, costing around $30,000 (£15,000). Other devices could then be developed with higher resolution or a wider field of view, said Professor Humayan. Future work includes studying the effects the implants have on the brain. "We are actually studying what happens to the visual cortex over time," said Professor Humayan. The research was presented at the American Association for the Advancement of Science (AAAS) annual meeting in San Francisco, US.

ping.
This might not be what you're looking for, but organ transplant ping. wall.
We are Borg.
And there were no accompanying pictures.
Bionic Foot Gives Leg Up!
And yet America is hated...
It would be interesting to subtract all that America has invented and given the world over the last 150 years and see what would be left.

Thanks, not rally up on my HTML.
Or typing for that matter.
Meanwhile, the Muslim world is stuck in the 7th century, its mind closed to God's continuous revelation, His never ceasing miracles, His eternal grace, His unlimited love for mankind, and His ceaseless creation.
*Sorry about that.
THAT'S IT!!! ;-)
Not a problem, if I apologized for every time I made a typo I be spending twice as much time posting. ;-D

On the other hand, there is a prophecy known among Orthodox Christians, that in the days of the Antichrist all of Christ's miracles will be reproduced, save that the dead will not be raised. The prophecy does not say the Antichrist will reproduced Christ's miracles, only that they will be reproduced.
I am happy for the blind who will see, but this is the first step in direct digital-brain interfaces (the retina is neurophysiologically part of the brain, and includes not just light sensing cells, but cells that start the image-processing involved in discerning shapes), and after one gets over the 'ooo! cool!' reaction to being able to access the internet through a direct retinal feed, a little more imagination and a little sober thought shows that this will not be a good thing. (If imagination of the consequences fails, I suggest viewing the entire corpus of Ghost in the Shell anime. It just gives a fairly dark vision of a democratic society with pervasive digital-brain interfaces. Consider then a non-democratic society.)

You might have missed the earlier ping, and normally wouldn't ping again, but shouldn't this article be pinged to your pinglist?
Well, I would hope that they look ahead... If they looked backwards, all they would see (in most cases) is grey matter...
Well, the rest of the world would be driving cars and we wouldn't.
Of course, this would solve our so-called Oil Addiction... So, there's an up side to everything I guess.
(We'd also be hurting some on the physics side but just the loss of the automobile would be pretty hard.)
Oh, and antibiotics...And manned space flight/satellites in orbit...
The USA has nothing to be ashamed of in the inventions/achievements department. But... We didn't invent everthing. There are a lot of bright people doing things all over the place.
The big market in these things isn't going to be the blind- it will be sighted people.
As soon as the bugs are worked out and the resolution is high enough it would be an excellent way to connect two people (or two million) and let the audience see 'what I see'. All you need is a transmitter/receiver like a mobile phone has and you can receive what your friend is looking at or send the friend what you're looking at. Also, you could simply send your imagery (or your visual life as it happens) to a hard drive for storage of everything you see. That last will evolve into directors making feature length visuals as an art medium (would give a whole new meaning to war/porn movies).
The military will get their hands on it first I reckon but civilians will have their day in the sun too. At some point nothing important will go unnoticed- if I witness it, the whole world will witness it. It will change the way we deal with murder and other crime. It will change politics, geopolitical conflict... Everything.
bookmark for later
You will absolutely see the things I described happen (assuming you don't pass away too soon).
If I had to choose between the two, I'd take sight over hearing any day. I wouldn't take invasive surgery for a hearing device that connected me to my friends when a phone works just as well. But the ability to send/receive exact visuals to/from self/others would be an awesome thing.
Also, partial blockage of vision by the gizmo will be worked around. They'll splice/jack the feed straight into the optical nerve behind the retina at some point. It's going to happen. Completely obvious in my opinion. The good thing here is, it's going to happen soon. I should see this in my lifetime.
Humanity will be profoundly changed. It will be interesting and frightening for those of us who were born before these things but for those born in that time they won't think twice about it.
Instead of replacing our biological eyes with improved digital eyes, it would be better to simply add the digital eyes externally. My choice would be to mount them on the ends of two steerable "bunny ear" masts, which would in turn be mounted over the ears. By having an extra (better) set of eyes mounted on the end of these steerable "eyestalks", the wearer could see in all directions, around corners, or quadroscopically. Later, when digital ears are produced, these too could be stalk-mounted, giving the wearer a 360° sight and sound experience.
For a normally sighted person this would be a luxury device that they could cut on and off (and see as normal when it wasn't in use). You could easily use computer programs with the device as well to create a visual overlay onto your own field of vision. For example, targeting devices could be displayed directly onto your vision without blocking what you were looking at. You could switch to infrared if you needed to. But you could immediately switch from that to a book you're reading (but the words could be scrolled on a screen that was projected onto your vision). Or a music video/movie. You could stop reading and immediately receive incoming visuals from your children/lover/friends etc (complete with sound via a cochlear implant ;-).
The cool thing is not so much the digital/optical feed but the ability to interface computers to the brain... Just a rough estimate assuming 10 million bits are flowing through your optical nerves right now- that's what- just over a megabyte of bandwidth straight into the brain? Not too shabby. A lot of computer/internet things could be made redundant and one megabyte would offer a really good effect. And that's just through the optical nerve. One step further has them plugging straight into the brain. The multiverse is the limit after that.
I would like to have some gadgets like you're talking about as well. They would fit into my structure as well.
These stories seem to be coming out in clusters http://www.freerepublic.com/focus/f-news/1785339/posts
And then the government will demand to implant one of these in the eyes of anyone who is even remotely suspected of being a terrorist.
And then the warrantless wiretaps, so to speak...
NO cheers, unfortunately.
Most moms already come equipped with these.
Cheers!
But if you could look at your own brain, don't you think that would be kinda cool?
It's dark in there.
In more ways than one.
You will be assimilated.
Resistance is futile.
Sounds like the Dems.
*Plus the rims of the glasses can be seen at the edges of the field of vision, and the parts of the nose where the glasses' rubber things touch can get a bit sweaty.
Hmmm. My ex-wife is an ENT surgeon. She doesn't believe that the current state of surgical procedures is going to stay this way forever without improvement. Do you? Do you think we are as far advanced as we will ever be? That this is as far as human achievement makes it?
Come on.
The technology is decades away from providing what God gave you when you were born.
You sound like it's millions of years. Decades is not long at all. 30 years. Not more. Don't know how old you are but I plan to see it happen because it definitely will happen- and soon. One century is soon- think about it. But it will happen much sooner than that.
We are wired to use our senses as infants
Actually not. You are wired to make concsious use of only a very small portion of what your sensory arrays take in. Most processing goes on outside the sphere of consciousness. We are not wired to 'use our senses as infants'. We are only aware of a very small amount of what actually comes into and goes on in our minds at any given moment. Your thoughts are created for you in your unconcscious mind before you ever get the chance to concsiously think about them. The fact is, not a lot is known about the unconcsious/conscious interface. It would be better to say we are wired to make use of the flimsy, low band-width tool of concsiousness when we are infants. Sight is not merely visual input- it is interpretation.
When you use 'sight', you are not seeing the world as it is. Sight is what the unconcsious mind has made out of sensory input plus the modifications and adjustments (like depth perception, colour, white balance, presenting you with what you expect to see etc).
The mind is a very adaptive piece of equipment. Why are you able to interface with the monitor in front of you right now but would be unable to do so once the medium is one step closer to you? (although chimpanzees have already been wired to do this. Chimps are more capable than us- I don't think so.) Adding signal to the existing input would simply be processed by the unconcsious mind the same way any other new and unusual visual input would be. Your mind would adapt to it just fine and learn to use it without you even thinking about it- literally.
We are decades away from engineering simple things like artificial limbs with touch and position sense wired directly into severed limbs.
Again, no. Artificial limbs wired directly to the brain have already been created and are being tested on real humans and chimps as we speak. This is happening right now. Not decades from now.
With the steady progress in technology, it will in the end probably be supplanted by bio-engineering anyway.
I want infrared vision and an array of tools on the end of artificial arms that can do a number of things- not just biotech engineered artificial eyes that accomplish the same thing that nature does. What's the point in that? The military would be very interested in these things as well. There is enormous enormous potential for these things. That alone will ensure these things come into being.
Mark my words- we are just around the corner from having mobile phones built directly into our heads. If they can wire your brain to an artificial arm they can wire it to a Sony Playstation Controller- yes/no? Obviously yes. You can do quite a lot with a Playstation controller. With different combinations of menus, a mental/virtual controller (wirelessly connected to a processor externally) could be used to manipulate objects, keyboards, switches- all sorts of things. We create text messages on our phones now by having one thumb choose between about 15 tiny keys. The thumb is a clumsy implement but it works just fine. People do it without hardly thinking about it. Imagine taking the thumb out of the picture (and the phone too). With menus, keyboards, options overlaid on your vision and cursors controlled by your mind the same way the mind is controlling artificial arms right now as we speak- the possibilities would be astounding.
I think it will be a lot simpler to do this than most people realise. I think the mind is set up to handle this, it is set up to create this and it will want to have this once it becomes available safely and cheaply.
Yep. Pornstars will become the biggest celebs in the world.
And then the government will demand to implant one of these in the eyes of anyone who is even remotely suspected of being a terrorist.
LOL. There won't be anyone without these things once they hit the market. In 1998 almost nobody had mobile phones. Now, in less than ten years, almost everybody has a mobile phone. People want to be connected. The mind wants to be connected. You can say what you want but you are going out of your way to connect to me (and god knows who else) right now. You are plugged into a global network, you can be traced, the things you write here can be used by some other entity.
It's already that way. There will always be negatives to everything.
Why not this alternative: Rather than the government calling the shots- why wouldn't WE the People demand that all government officials have their devices turned to 'transmit to all' all the time? That way WE could keep track of what THEY do? I'd quite like that actually.
Something else to think about- this is probably a natural 'next step' for humanity. No getting around it. But, who says governments and nation states are going to be with us forever? I don't think they (nation/states & governments as we currently understand them) will last.
