BrainPort Lets the Blind "See" With Their Tongues
Hugh Pickens writes "Scientific American reports that a new device called 'BrainPort' aims to restore the experience of vision for the blind and visually impaired by relying on the nerves on the tongue's surface to send light signals to the brain. BrainPort collects visual data through a small digital video camera and converts the signal into electrical pulses sent to the tongue via a 'lollipop' that sits directly on the tongue, where densely packed nerves receive the incoming electrical signals. White pixels yield a strong electrical pulse and the electrodes spatially correlate with the pixels, so that if the camera detects light fixtures in the middle of a dark hallway, electrical stimulations will occur along the center of the tongue. Within 15 minutes of using the device, blind people can begin interpreting spatial information. 'At first, I was amazed at what the device could do,' says research director William Seiple. 'One guy started to cry when he saw his first letter.'" There is some indication that the signals from the tongue are processed by the visual cortex. The company developing the BrainPort will submit it to the FDA for approval later this month, and it could be on sale (for around $10,000) by the end of the year.
Oooh hello pretty lady, come on over here and let me get a good lick at you.
Fascism trolls keeping me up every night. When I starts a preachin', he HITS ME WITH HIS REICH!
"Taste the rainbow" was the first thing that came to mind when I read this.
Does that mean ugly girls "taste like shit"?
I'm pretty sure I read about this exact thing years ago. Weren't there issues with the tongue being "low resolution" and interfering with eating and talking?
The human brain is adept at processing pattern streams. These are two-dimensional datasets that change over regular intervals of time. In the specific case of this tongue-sight project, they are taking advantage of the ability of the tongue to transmit many "pixels" of sensory information in a square grid. Which pins poked into the tongue governed what the brain got that instant of time. So, by reading the changing pattern of the dots, the brain can learn to process that pattern stream in the same way it learns to process the pattern stream that is the million or so "pixels" of information each eye sends, each unit of time. The left brain hemisphere processes Linear-Sequential Information. The right brain hemisphere processes Visual-Simultaneous Information. We know that from the Nobel-prize-winning [1980] research of Dr. Roger Sperry. Current computers process information in a linear, sequential fashion--much like the left hemisphere works. The true breakthroughs in AI will come when we can process and interpret the pattern streams that reach the right hemisphere, the image-oriented streams. The complex interplay between the faster linear-sequential hemisphere and the holistic visual-simultaneous hemisphere is what creates consciousness. This tongue-stream is a great idea.
So what does blue taste like?
Sure, the resolution won't be as fine but it will be a lot less obtrusive to wear a sensor wrapped around your torso than to have something on your tongue with a wire sticking out of your mouth.
A practical version of that sensor net the blind lady wore on Star Trek back in the '60s will likely be on the market before 2067, assuming technology doesn't leapfrog it entirely.
Knowledge is how to play a game, intelligence is how to win, wisdom is knowing what game to play.
I don't know if I'm the only one who's absolutely amazed by this.
About 20 years ago I thought of a device for deaf people to "see sound" after reading that researchers have learned to read spoken words from from gray-scale sound spectrograms (frequency plots).
Now an off-the-shelf PDA or iPhone could probably do the trick of showing a plot with the right software. Some slashdot readers claimed it's too hard to learn if you never heard sound before. But it may be worth a try. Besides, some deaf people used to hear before an injury or illness. It's basically pattern-recognition, something humans are pretty good at given sufficient feedback.
Perhaps these devices can be combined and the frequency plots could flow through the tongue. However, I suspect there's insufficient resolution that way, and eyeballing it would be better. But, it's worth a try.

Table-ized A.I.
From TFA:
Seiple works with four patients who train with the BrainPort once a week and notes that his patients have learned how to quickly find doorways and elevator buttons, read letters and numbers, and pick out cups and forks at the dinner table without having to fumble around.
OK, but then what do they do with it. They'll be able to pick a fork or spoon up, but they won't be able to see where the food on the plate is one they start eating. After you pick up the fork and begin to feed yourself, this things kinda worthless.
There is no "I disagree" mod for a reason. Flamebait, Troll, and Overrated are not substitutes.

Now they must build magnetic orientation belts, infrared patches and smelly radiation detectors.
I don't have the link ready to hand, but the technology behind this was posted to slashdot quiet a while ago. (At least many months, possibly over a year ago) Anyway, I was wondering when we would hear about this technology again, since it has tremendous potential both for sight-restoration applications, as well as furthur development towards the integration of machine and brains. If the resolution was high enough, for instance, a pilot could use this to see underneath the plane, or in other directions normally blocked. The potential application for guided search and rescue, and other remote controlled devices is also large. "being" there is better than simply seeing on a screen, after all, even if virtually. I hope that the various gov't and none-profit groups that support the visually impaired take note of this as a way to help people become active and contributing parts of society again. It's nice to take care of the impaired, but better to help them regain their independence.

This man has the right of it.
This is the most promising bit of cybernetics news I have seen in quite a while. I've been hoping that some day within my lifespan artificial senses could be used. Well, now it looks like they can. Maybe they make for low-resolution video, maybe they can be used for information readout. Yeah, it would look weird, but this can give you (for example) a read heads-up display that doesn't interfere with your vision. Or an interface for processing senses from remotely controlled robots. Imagine the fun business users would have being able to "read" their email while driving. The possibilities are endless.
to accept the praise of personal wisdom is an affront to the very ideal i hold dear.

Not actually for sale yet so who knows, but I'd love to give it a try.
You can read all about the work leading up to this device, why it works, amazing stories of recovery from brain injury, and other cool stuff in a book called The Brain That Changes Itself.
This is one of the best books I've ever read.
In the course of every project, it will become necessary to shoot the scientists and begin production.
Would this still work for them? Seems like it would not.
Tsukasa: All I really want, is to be left alone...
I'll get one of these, mount the camera part on the back of my bike helmet, and be able to "see" both forward and backwards at the same time!
I can finally get rid of that helmet-mounted mirror, so I won't look like a dork anymore!
I don't care if it's 90,000 hectares. That lake was not my doing.
What happens when you burn your tongue? Does your "sight" degrade or get blurry while your taste buds are being repaired?
Fry: Did everything just taste purple for a second?
This is an application of neuroplasticity.
A scientist developed long time ago a special chair that enabled to remap the vision function for blind people without the need for using their eyes, he developed an other device for NASA astronauts to remap the missing feeling of touching when working with thick gloves.
Neuroplasticity is detailed in an entire book by Norman Doidge, MD | The Brain That Changes Itself.
From the book: Neuro is for neuron, the nerve cells in our brains and nervous systems. Plastic is for changeable, malleable, modifiable. At first many of the scientists didnâ(TM)t dare use the word neuroplasticity in their publications, and their peers belittled them for promoting a fanciful notion. Yet they persisted, slowly overturning the doctrine of the unchanging brain. They showed that children are not always stuck with the mental abilities they are born with; that the damaged brain can often reorganize itself so that when one part fails, another can often substitute; that if brain cells die, they can at times be replaced; that many circuits and even basic reflexes that we think are hardwired are not. One of these scientists even showed that thinking, learning, and acting can turn our genes on or off, thus shaping our brain anatomy and our behaviorâ"surely one of the most extraordinary discoveries of the twentieth century.
In the course of my travels I met a scientist who enabled people who had been blind since birth to begin to see, another who enabled the deaf to hear;
The book is a must read.
The insides of the cheeks are not as sensitive but the available area is larger, binocular vision might be possible, and it might be possible to leave the electrodes in while talking and perhaps even while eating.
(My wife's idea, not mine.)

Tactile reaction time is faster than visual reaction time. If the resolution is high enough and the switching time fast enough, could this system be advantageous where fast reactions are needed (eg. games, sport, driving, combat, etc.). Could it be combined with normal vision for a kind of minor precognition?
How about using it for extended vision with more frequency channels, wider or narrower field of vision, faster automatic brightness control, etc? Touch has multiple channels but how many are high enough resolution to be useful?
As anyone who's used psychedelic drugs will know, the human visual system is bottlenecked by the eyes. The brain can certainly handle more powerful sensors so we should be working on making them.
So what does this mean for blind hookers?
If you coated a retainer with the visual surface, it would then attach to the teeth, and you could see by pressing the tounge to the roof of the mouth... or drop the tongue to speak/drink (not sure about eating, do you normally take out the retainer?)
meh
I'd love to be able to see tastes - that is, have my sense of taste piped to the brain as vision instead of taste. I wouldn't want my vision permanently replaced, but I'd love to experience the brain visualising what I taste. And hey, instead of the usual 3 dimensions (or more if you're lucky), you'd have 5 factors to go with.
This almost sounds like an induced form of synesthesia, a condition where someone's senses operate involuntarily as a merged experience. For example, sounds that generate visual feedback or brief changes in taste.

That's a great idea.
Interesting, but the fatal flaw is there's a possiblity of tasting this.
What I want to know is, will this work for a sighted person? If the tongue seer is looking at one scene, and your eyes are looking at another, can the brain sort them out and allow a person to see two different things at once. Meaningfully, I mean. If so, there could be a lot of applications. And implications. If the brain can see in two directions at once, we could extend our visual senses in all kinds of ways.
