In this fascinating talk, interaction designer James Patten discusses the intangibility of touchscreens. He introduces the Sense table: a smart sensing platform that tracks the distance of objects on it. It is a versatile device that has been used to make music just by moving objects, to visualize financial data and even to teach kids about chemistry.

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.
