Advances in Technology for the Blind

There is another great article and video published on ABCNews.com that talks about new advances in technology that has been created to help the blind.  The new technology prints photos that allow them to feel the facial features and ultimately recognize the photo.  The technology research is being led by an ASU associated professor and they are trying to get software companies to put it on the market.  I see this as being a technological advance that makes you feel warm inside.
