How BrainPort Works

The BrainPort Vision Pro vision aid is a headset that contains a small video camera, user controls, a rechargeable battery, and the tongue array. Science Museum, London, October Supervised training is necessary prior to using the BrainPort Vision Pro device independently. Installation Begins on the 10, Year Clock. Archived from the original on 29 April The headset is fully adjustable and available in 3 different sizes to accommodate most users.

In one case, when blind mountain climber Erik Weihenmayer was testing out the device, he was able to locate his wife in a forest.

This might be age-related, including cataracts, glaucoma and macular degeneration, from diseases like trachoma, diabetes or HIVor the result of eye trauma from an accident. The encoded signal represents differences in pixel data as differences in pulse characteristics such as frequency, amplitude and duration. Giving Sight Carnegie Mellon University, A Certified Trainer will contact you to discuss the next steps!

If “seeing” means there’s activity in the vision center of the cerebral cortex, then the blind subjects rbainport really seeing.

Penn State University, April Three skills were tested with the following performance goals: Training is offered through certified, independent training facilities.

A taste of vision: BrainPort could provide vision-impaired people with limited forms of sight. The subjects could still feel the pulses on their tongue, but they could also perceive images generated from those pulses by teechnology brain.

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. This feature is available to authenticated users only. As expected, experienced users performed better than the new users, as performance improves with increased experience with the device. One of the most common questions at this point is, “Are they really seeing?

The camera works in a variety of lighting conditions and has an adjustable field of view. The optical information — light that would normally hit the retina — that the camera picks up is in digital form, techbology it uses radio signals to send the ones and zeroes to the CPU for encoding. 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.

Users who did not achieve the success criterion returned for 30 minutes additional training. Views Read Edit View history. This page was last edited on 11 Novemberat Use dmy dates from September All stub articles.
