This is a TED talk given by Pattie Maes from MIT labs. Here she demonstrates a wearable device with a projector that paves the way for profound interaction with our environment. She gives us a glimpse of what our digital world is going to be like and how we will be interacting with it,  say in 10 to 15  years time.

Really mind boggling in its simplicity and audacity. View the talk below and feel inspired.
