Design thinker and entrepreneur Sumit Dagar designs tools to help blind people engage with the world. He shows two concepts: a tablet that has reactive Braille capabilities and a phone with the same functions. With the ability to convert visual elements to Braille and even capture visuals and convert them, this could become a truly life-changing technology.

NOTE: Comments are disabled on this video. We made this difficult decision for the TED Archive because we believe that a well-moderated conversation allows for better commentary from more people and more viewpoints. Studies show that aggressive and hateful comments silence other commenters and drive them away; unfortunately, YouTube's comment moderation tools are simply not up to the task of allowing us to monitor comments on so many videos at once. (We'd love to see this change, YouTube.) So for now, if you'd like to comment on this talk, please use Facebook, Twitter or G+ to discuss with your networks.
