BRAINPORT VISION DEVICE PDF

White pixels yield strong electrical signals that some say feel like champagne bubbles, while black pixels give no signal. This technology uses the tongue because it is more sensitive and a better electrical conductor than other areas of the body, such as the hands or the back. The device can also be used to address problems of balance. Sensors transmit information about the position of your head, the amount of pressure on your feet and other bodily positions and then relay the data to your tongue, where you learn to interpret your position in space and make the adjustments you need to stand straight, or to walk without fear of falling. Developed by Wicab Inc. For example, when your head tilts to the right, your tongue receives stimulation on the right and when your head is in the middle, you can feel the pulses in the middle of your tongue.

For example, when your head tilts to the right, your tongue receives stimulation on the right and when your head is in the middle, you can feel the pulses in the middle of your tongue. After a while, your brain learns how to interpret these signals and you can correct your balance without thinking. They could control their body movements and walk steadily in a variety of environments with a normal gait and with fine-motor control.

They experienced muscle relaxation, emotional calm, improved vision and depth perception and normalized sleep patterns. For example, in , a team of researchers tested 12 healthy adults to see if they could stand still with their eyes closed. The biofeedback on their tongue did help them to balance, although the team agreed that more research was necessary. A demonstration project with 10 people began in Germany and distribution in Sweden and Italy are awaiting official approval.

In the U. He describes a woman who felt as though she was constantly falling, even when she was lying down. Cheryl lost her sense of balance when she took large doses of antibiotics to treat an infection after a hysterectomy. The vestibular system in her inner ear was so badly damaged that she had no idea whether she was standing, sitting, or lying down.

This also affected her vision, as every object looked as though it was shaking. Bach-y-Rita made a hat with sensors that could detect the position of her head and translate this information into messages that he could send to a small pad on her tongue.

She leans back from the table, keeping two fingers on it for contact. She lifts her fingers from the table. She starts to cry — the flood of tears that comes after a trauma; she can open up now that she has the hat on and feels safe.

The first time she put on the hat, the sense of perpetual falling left her — for the first time in five years. Her residual effect progressed to multiple hours, to days, and then to four months. Now she does not use the device at all and no longer considers herself a Wobbler. Silberman Books p.

BrainPort®

White pixels have a strong pulse while black pixels give no signal. The control unit converts the image into a low resolution black, white and gray picture, which is then recreated as a square grid of electrodes — around the size of a postage stamp — on the lollipop. Each of the electrodes pulses according to how much light is in that area of the picture. It converts pictures into electrical pulses and it is placed on the tongue.

How BrainPort Works

The BrainPort Vision Pro is being used by individuals with no usable vision, both congenitally blind and with acquired blindness. Good candidates for using the BrainPort Vision Pro are people that have completed conventional blind rehabilitation training and are comfortable using conventional assistive tools. A non-surgical solution, BrainPort Vision Pro does not affect the eyes. This is important in the event future research offers better alternatives for people who are totally blind. Training is offered through certified, independent training facilities. A typical training course is 10 hours of one-on-one training, over a three-day period, including customized content for the individual user. Fill out the patient survey here to determine if you are a good candidate.

BrainPort Vision Device

Photo courtesy Wicab, Inc. Test results for the BrainPort vision device are no less encouraging, although Wicab has not yet performed formal clinical trials with the setup. According to the University of Washington Department of Ophthalmology, million people in the United States alone suffer from visual impairment. This might be age-related, including cataracts, glaucoma and macular degeneration, from diseases like trachoma, diabetes or HIV , or the result of eye trauma from an accident. BrainPort could provide vision-impaired people with limited forms of sight. To produce tactile vision, BrainPort uses a camera to capture visual data. The optical information -- light that would normally hit the retina -- that the camera picks up is in digital form, and it uses radio signals to send the ones and zeroes to the CPU for encoding.
