CHAPTER 1
General Information
The BrainPort Vision Pro is an oral electronic vision aid that
provides electro-tactile stimulation to aid profoundly blind
individuals in orientation, mobility, and object recognition as an
adjunctive device to other assistive methods such as the white
cane or a guide dog. It translates digital information from a video
camera to gentle electrical stimulation patterns on the surface of
the tongue. Users describe the experience as streaming images
drawn on their tongue with small bubbles. With training, users are
able to interpret the shape, size, location and motion of objects in
their environment. BrainPort Vision Pro is not used to diagnose or
treat the underlying condition that led to the user’s visual
impairment.
Warning
The BrainPort Vision Pro does not replace the cane or guide dog.
The BrainPort Vision Pro is intended to augment, rather than
replace, other assistive technologies such as the white cane or
guide dog.
Training is required before using the
BrainPort Vision Pro.
Purpose of Device (Indications for Use)
The BrainPort Vision Pro is an oral electronic vision aid that
provides electro-tactile stimulation to aid profoundly blind patients
in orientation, mobility, and object recognition as an adjunctive
device to other assistive methods such as the white cane or a
guide dog.

Description of BrainPort® Vision Pro
Headset
The headset consists of the device controls, battery pack, and a
digital video camera that is mounted on an eyeglass-type frame. It
may be worn by itself or optionally with a pair of glasses or
sunglasses. The camera’s field of view is user-controlled and varies
from narrow to wide angle views. The Intra Oral Device (IOD) is
permanently attached to the left earpiece by a cable.
Intra Oral Device (IOD)
The IOD (tongue electrode array) contains electrodes that act as
“pixels” for the tongue. The flat side with the electrodes should be
in contact with the front top surface of the tongue. Close your lips
around the thin stem, maximizing tongue contact with the
electrodes. The stimulus pattern on the electrode array
corresponds to the scene captured by the camera. There is one
cable exiting the thin stem of the IOD that is permanently attached
to the earpiece of the headset.
Battery Charger
A battery charger with factory instructions and two lithium-polymer
rechargeable batteries are included.
Training and Training PC
Training is required before you use the BrainPort Vision Pro. The
trainer may use a personal computer or mobile device (e.g.: smart
