Implants Allow the Blind to See
gihan_ripper writes "Neurosurgeon Kenneth Smith has performed a revolutionary operation on St Louis resident Cheri Robertson, connecting a camera directly to her optic nerve. The rig is in principle similar to Geordi La Forge's visor, albeit in very rudimentary form. At present, the 'image' consists of a number of white dots, as on an LED display. There are also governmental restrictions on this research, forcing Kenneth and his team to fly to Portugal to carry out the operation. If this technology takes off, the future will be bright for the sight-impaired."
Camera tech is pretty well-known. Adding IR, UV, magnification, auto-adjusting for sunlight/night vision is all fairly trivial once you have the optic connection.
Imagine switching to sepia tone whenever you want that "wild west" feel.
The hard part, of course, is the resolution. Stimulating specific optic nerves is tricky, but fortunately your brain is good at dealing with odd input even if you don't get the connection quite right. It reminds me of the experiment where someone wore mirror glasses that flipped the world upside-down. After a week or so, everything seemed normal.
Why are there restrictions on research such as this? What kind of restrictions and how did they come about?
Last I heard -- several years ago -- they had enough resolution to see a a black/white machine just about comperable to a single ASCII character rendered on a 1985 era CRT. That would mean an "image" would have about as much clarity as, say, one of the falling mushrooms from an original Centipeded game. Not exactly high res, but a positive step.

If they're not already, DARPA will be all over this like stink on a monkey. They'd love to have soldiers will what will amount to wallhacks.
On an unrelated note, if they could make it so that they didn't need to cut open my head to do it, I'd love to have infrared/ultraviolet/telescopic/ultrasonic vision.
Article states that electrodes are implated into the back of the brain. If it really were the optic nerve it would be more significant, less danger = wider adoption.
True genius is grasping a situation like a peice of fruit, and peircing it just right so that it drains dry.
I must admit, I find it very difficult to trust any "journalism" with that many exclamation marks: "With the help of a device, she could see again!" This is written a lot like a press release, not a news article. Has this not been published in any major scientific journals?

I'm a student at UCLA working on a similar project called Retinal Prosthetic writing code in Visual C++ and Intel's OpenCV library. Check out their site:

We're running a simulation of what the surgeon is doing by having the subject wear goggles with a s-video input (it's those fancy expensive goggles to watch movies or to game on). Similar to the article, a camera is attached to the front of the goggles. The input feeds into the computer, chugs through my code, and displays an image meant to simulate varying amounts of electrodes (4x4, 16x16, 64x64) in various configurations (wide screen vision anyone?). All this goes on while the subject tries to accomplish tasks (writing a check, discerning between a fork and knife, etc).
Also, check out a company working on implementing this idea:

Joking aside, I find this very interesting. I have a hereditory, degenerative eye disease called retinitis pigmentosa (http://en.wikipedia.org/wiki/Retinitis_pigmentosa ) which I was diagnosed with when I was very young. Being hereditory my Mum, Nan and Uncle all have this condition as well, and I have also found older relatives on cencuses who are marked down as 'blind', probably indicating that they also had the condition.
The condition worsens with age, so at the moment I am not too bad. I don't have any night vision and so I struggle in dark rooms or out at night time, but during the day I am OK. As people with RP get older, especially into 40s, 50s and beyond blind spots can develop, as well as tunnel vision or even total loss of vision.
I was surpised recently to find out that our car park attendant Dave here at work also has the condition since it is very rare (I think approximately 10,000 people of 56 million in the UK have it). Dave is in his 50s and in the last six months his vision has deteriorated rapidly such that he was registered partially sighted and the actually registered blind. He now has to walk with a white stick and has been retired from work, which is a lot to come to terms with in the space of a year or so. Sadly it took him more by surprise because it had skipped a generation in his genes and so neither of his parents had it and could explain it to him.
I am only 24, it gives me hope to think that in the next 25 years or so this research may develop to the point where it is commonplace, and that if I did lose my sight I would simply be able to book an appointment to get my visor fitted and that would be the end of it!
