A device named BrainPort V100 has been approved through FDA (Food and Drug Administration) in US before the availability for sale. It’s a gadget which seems like a pair of sunglasses which aids the blind users to figure out what do they have in their surroundings just by the use of tongue array which is already attached with the spectacles. The spectacles assist the user by translating the surroundings into the electrical pulses to let them know what is happening around them. Once a user learns how to decode it, they become capable enough to know whether the objects around them are stationary or moving at that time.
This is like an upgraded version of Braille
Wicab(Parent Company) describes BrainPort V100 as a "400-point refreshable braille" device, and mentioned it as the like "sparkling water or vibrations" felt on the tongue-by using the remote attached the user can also change the strength and frequency of pulses as well. The company Wicab says this equipment is found to be the most appropriate for the ones who have no constructive vision.
Before wearing the spectacles the user must have a minimum training of 10 hours by the certified trainer or expert otherwise you cannot step out on your own.

It is reported by Wicab that 69 percent users which were selected for testing BrainPort V100 recognized the subjects around them after a good practice of one year. It is very efficient when the pulses on your tongue go off.
