BrainPort dedicate themselves with BrainPort V100 to help blind people with their new device called BrainPort V100. It is for sale in the United States after the Food and Drug Administration have given a green light to proceed. It is not completely bring back vision (for the time being) or replace guide dogs. But it will send signals through the tongue and it will be interpreted by brain.
The new BrainPort V100 has much smaller design compare to their prototype. It has a camera and a wired sensor that will send the signals. Me personally really love this project because it will give hope to those who loose their sight.
