A new device called the vOICe helps people to recognize what is happening around using the appropriate sounds. Such a device can be successfully used for the treatment of blindness, according to the magazine, The Sydney Morning Herald. vOICe can safely be called a full replacement for the eyes.
The device converts the image received from the camera, in a special audio track. Pitch and brightness associated with the volume. As a result, the orientation in space with the help of the video located on the horizontal axis. The image refreshes every second and has a resolution of 60x60 pixels.
Scientists at the University of British Bat asked for visually impaired people to test the new device. As a result, people even without any prior training managed to pass all the tests of view. Interestingly, the obtained results were better than after treatment with stem cells or establish implants.
In the course of the study volunteers ran the standard test Snellen (table with rows of letters, whose size gradually decreases from top to bottom). Currently, the normal term is 20/20 (of course, it takes into account the size of the letters and the distance to the table). The participants of the experiment showed a stunning result - 20/400, which is by far the best for invasive technologies.
