For as long as the researcher with a number of scientists from MIT and other institutions, engineers, doctors and opticians, as well as - 30 students from the same MIT has designed and built a wonderful machine, the surgeons returned to her sight in one of his eyes.
But the woman did not retreat from the venture, testing an experimental car in his blind eye. "While we have not experienced it on other people, I was the creator, and a guinea pig".
But how, finally, to arrange a "visual machine"? Diagnostic abilities, like SLO, it was not required, and it is already possible to simplify the design. But the inventor went on. It replaced the expensive laser on the LED - a large, very bright and more or less cheap.
Light from the diode passes through a translucent liquid crystal matrix, which forms a PC running a black and white image with a resolution of 640 x 480 pixels, with 8 levels of gray. The image is projected through the lens onto the retina.
Its cost was $ 4000 - 25 times less than the prototype - a diagnostic machine SLO. A possibility was higher.
More recently, Elizabeth has tested its "visual machine" almost blind for 10 people. Each visual acuity in the best eye of not more than and many - were much lower.
Six of the 10 patients identified 10 words visual language correctly. Two more volunteers correctly interpreted the words of 9 out of 10, and two - 8 out of 10. But without a car, all these patients were too visually impaired to have any hope of reading.
Now these people were again able to see the face of another person, and even after the designer of "walk" on the virtual buildings.
By the way, the inventor of the machine says that seeing people, prompting a road to the blind, are often mistaken. And the opportunity to walk along the corridor of the building, see the twists and find yourself, for example, the number of doors to the right person room, before actually going in this place - well worth it. And there, staring, and portable version of the device will appear.
"Most blind people have to regain the ability to see pictures in the galleries".
