Training is offered through certified, independent training facilities. To the extent that a trained user may simultaneously distinguish between multiple of these characteristics of amplitude, width and frequency, the pulses may convey multidimensional information in much the same way that the eye perceives color from the independent stimulation of different color receptors.

After training in laboratory tests, blind subjects were able to perceive visual traits like looming, depth, perspective, size and shape.

They could perceive and identify letters of the alphabet. Ready to buy or try a BrainPort Vision Pro?

Brainport – Wikipedia

BrainPort Vision Pro translates digital information from a wearable video camera into gentle electrical stimulation patterns on the surface of the tongue. Views Read Edit View history. The headset is fully adjustable and available in 3 different sizes to accommodate most users.

This feature is available to authenticated users only. Giving Sight Carnegie Mellon University, 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.

How Chemical Sensing Devices Work. 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.

How BrainPort Works

You can help Wikipedia by expanding it. Fill out the patient survey here to determine if you are a good candidate. Not to be confused with Bainport Netherlands. The following study demonstrates “visual skills” in acuity, object recognition, orientation and mobility provided by the BrainPort vision device. If seeing means you can identify the letter “T” somewhere outside yourself, sense when that “T” is getting larger, smaller, changing orientation or moving farther away from your own body, then they’re really seeing.

Retrieved 4 October 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.


Archived from the original on 29 April This page was last edited on 11 Novemberat In this scenario, a camera picks up the image of the surrounding, the information is processed by a chip brainprt converts it into impulses which are sent through an electrode array, via the tongue, to the person’s brain.

As expected, experienced users performed better than the new users, as performance improves with increased experience with the device.

BrainPort is a technology whereby sensory information can be sent to one’s brain through an electrode array which sits atop the tongue. Visually impaired persons will be able to use device to sense images on tongue” Brainplrt. To produce tactile visionBrainPort uses a camera to capture visual data.

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