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."
Can I get the infrared/untraviolet model?
A blog about stuff.
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.
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.
So sad that massive bureaucracy and misinformation makes this kind of research too difficult and expensive.

Unfortunately the operation to remove one's head from one's ass is banned in America due to government restrictions
The revolution will not be televised... but it will have a page on Wikipedia
It's important to note that due to the way the human brain develops synaptic connections in the visual cortex, only humans who had sight from birth to some age beyond 3 to 5 years of age will benefit a great deal from such a procedure. While people who are blind from birth due to cataracts or other conditions obtain some visual perception when the cataract is later removed, most never develop the neural connections that allow them to identify what they're seeing. Everything from navigating around desks in a well-lit classroom to differentiating a face from a table, a television, a light bulb, or an automobile is all but impossible if the visual cortex doesn't develop properly in response to normal visual stimulus from birth. Sight is useless without the ability to percieve what one is really seeing. So while this is incredibly impressive and promising for people who had sight but lost it, don't expect that this will be a cure-all to allow people with all types of blindness to see again.
I do feel it has become too much though - I don't believe it is the government's job to prevent us from making rash decisions.
If you don't know where you are going, you will wind up somewhere else.
