After training in laboratory tests, blind subjects were able to perceive visual traits like looming, depth, perspective, size and shape. This is important in the event future research offers better alternatives for people who are totally blind.

How BrainPort Works

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.

The following study demonstrates “visual skills” in acuity, object recognition, orientation and mobility provided by the BrainPort vision brainpotr. The encoded signal represents differences in pixel data as differences in pulse characteristics such as frequency, amplitude and duration.
