New research shows how, by converting sights to sounds, the brains of congenitally blind people respond similarly to various objects in a similar way to people who can see.

It has been long established that the brains of people blind from a young age compensate for the lack of visual input by putting more emphasis on the other senses. A new insight has been provided in the way that sounds help blind people to “see.”

In a new study, blind participants used an augmented reality system that converts images into sounds. It was found that the brains of blind and sighted people sometimes react to similar objects in much the same way, despite vastly different sensory inputs. Augmented reality (AR) is a live, copy, view of a physical, real-world environment whose elements are augmented (or supplemented) by computer-generated sensory input such as sound, video, graphics or GPS data… see more
