BrainPort is a technology whereby sensory information can be sent to one's brain through an electrode array which sits atop the tongue.
[2][3][4] 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.
In this scenario, a camera picks up the image of the surrounding, the information is processed by a chip which converts it into impulses which are sent through an electrode array, via the tongue, to the person's brain.
This is similar in part to how a cochlear implant works, in that it transmits electrical stimuli to a receiving device in the body.
[5][6] The BrainPort V100 oral electronic vision aid was approved by the Food and Drug Administration (FDA) on 18 June 2015.
