According to the United Kingdom the times "reported that the United States introduced a package of special brain Visual device which relies on the surface of the tongue of the blind will light signal transmission to the brain, thus helping the blind to" see "all the world.
Researchers said that this could completely change the lives of blind persons.The port named "the brain" (BrainPort) brain Visual for the United States of Wisconsin, major r Wicab accessories including a pair contains hidden-camera, sunglasses, handheld controller, central processor and is similar to the electrodes as Lollipop.
"Lollipop" is a 9 cm size, matrix group, the arrangement of electrodes will be posted directly on the surface of the tongue.Glasses of miniature hidden cameras is responsible for the collection of visible data, users put on this special glasses, the visible data bypasses the eyes, is passed to the handheld controller, central processor responsible for digital signal is converted into electrical pulses through the processed signal through the "lollipop" electrode films are transferred to the surface of the tongue, let the tongue can detect objects of image, followed by neurological transmission on the tongue to the brain.
Electronic pulse in space is encoded, which means that the tongue to receive these signals can be perceived depth, angle, size and shape.
This information is transformed into images of human brain, but due to the low resolution of the image is still rather vague.Now 24-year-old Clegg · Rund Bo is the first port of the "brain" of the device.
In 2007, Rund Bo in the Iraq war was in grenade attack, causing the right eye completely blind, desperate he thinks he has to rely on the rest of the guide dog or other care. However, he was very lucky to be United Kingdom Ministry of defence selected, became one of the first experience. With the device, Rund Bo can correctly read out the distance he 1 m far from the card's three-letter words, such as CAT; he will also be able to see the approximate outline of objects and independent walking.Bo said, this equipment will allow him to clear the way forward "Tiger", don't trip over, greatly changed his life, however, it is just a mobile device, and is not a panacea, that also will not let him and exactly the same as normal people.
The researchers indicated that, at present, the "brains" lollipop "port" electrode plate unit 400 points to send to the tongue surface information to point to 4 000 to greatly improve the image of precision.
However, the "brain port" weaknesses is that blind users "to see" around the world, but not be able to speak or eat things designers want to be able to produce more compact equipment, can be permanently placed in the teeth or oral palate behind the site, to allow people to use more convenient.
