Of course, the other bonus of our new and improved pocket computers, rather than just their mobility and connectivity, is that they have more than just cameras to get a measure of their surroundings. There are microphones that can detect wind or sound, accelerometers for movement, digital compasses to tell which direction we're facing and proximity sensors as well. Now we're in a place where we can really experiment with AR on a personal level and explore our worlds in a whole new way.
