There's an app for that: "Matt Mills: Image recognition that triggers augmented reality"

The app demonstration was very interesting to watch because it shows how much technology has advanced. It is able to pick up videos by simply turning the camera to an object of choice, which is a way for individuals to have more background information/ be more open to what is going on around them. I cannot imagine what other application exist out there, but to my knowledge, there's pretty much an app for anything. One of the most useful apps for me is the DART app. It helps me get to places i need to go by providing exact times and which train/bus to take. It is not my favorite, but definitively useful to manage my time.
