Amazon Fire Phone Uses 4 IR Cameras for 3D UI

The Verge, Mashable: Amazon Fire Phone uses four front-facing IR cameras to create a 3D user interface: "Perhaps the most useful application shown off so far is simply tilting the phone to scroll through a web page like The Washington Post or to page through a Kindle book. Of course, we've seen other tilting features before and they've a lot to be desired, but Amazon's demo seems to make these features seem far better than previous attempts. The question will be whether or not the extra processing power and potential battery life drain to run these multiple cameras will be worth it."
