The BrainPort Vision Pro is being used by individuals with no usable vision, tecunology congenitally blind and with acquired blindness. The brain eventually learns to interpret and use the information coming from the tongue as if it were coming from the eyes.

In the next section, we’ll see which BrainPort applications Wicab is currently focusing on in clinical trials, what other applications trchnology foresees for the technology and how close it is to commercially launching a consumer-friendly version of the device.

One study that conducted PET brain scans of congenitally blind people while they were using the BrainPort vision device found that after several sessions with BrainPort, the vision centers of the subjects’ brains lit up when visual information was sent to the brain through the tongue. USA – Rx Only. BrainPort could provide vision-impaired people with limited forms of sight.

Visually impaired persons will be able to use device to sense images on tongue” PDF. It has also been developed for use as a visual aid, demonstrating its ability to allow a blind person to see his or her surroundings in polygonal and pixel form.

Bach-y-Rita founded Wicab in When in use, white pixels from the camera are felt on the tongue as strong stimulation, black pixels as no stimulation, and gray levels as medium levels of technoloy. A typical training course is 10 hours of one-on-one training, over a three-day period, including customized content for the individual user.

Three skills were tested with the following performance goals: As expected, experienced users performed better than the new users, as performance improves with increased experience with the device. To produce tactile visionBrainPort uses a camera to capture visual data. In one case, when blind mountain climber Tehnology Weihenmayer was testing out the device, he was able to locate his wife in braainport forest.

The CPU runs a program that turns the camera’s electrical information into a spatially encoded signal. Purchase this article with an account. Fill out the patient survey here to determine if you are a good candidate. You can help Wikipedia by expanding it.

A Tongue for an Eye: Users form a spatial reference with a few hours of training, mapping cutaneous information on the tongue to their environment. The camera works in a variety of lighting conditions and has an adjustable field of view.

The encoded signal represents differences in pixel data as differences in pulse characteristics such ttechnology frequency, amplitude and duration. Views Read Edit View history. Taste the Sights Around You? Installation Begins on the 10, Year Clock.

Training is offered through certified, independent training facilities. Multidimensional image information takes the form of variances in pulse current or voltage, pulse duration, intervals between pulses and the number of pulses in a burst, among other parameters. As shown by these data, both new and experienced users demonstrated significant improvement in visual acuity, object location and grasping accuracy, and accuracy and speed of sign identification.

Users feel moving bubble-like patterns on their tongue which they learn to interpret as the shape, size, location and motion of objects in their environment. The subjects perceived the objects as “out there” in front of them, separate from their own bodies.

A non-surgical solution, BrainPort Vision Pro does not affect the eyes. 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 technolovy.

Ready to buy or try a BrainPort Vision Pro? The following study demonstrates “visual skills” in acuity, object recognition, orientation and mobility provided by the BrainPort vision device. In this scenario, a camera picks up the image of the surrounding, the information is ivsion by a chip which converts it into impulses which are sent through an electrode array, via the tongue, to the person’s brain.
