Its been months that we have been hearing chatter about a smartphone from Amazon, with a 3D interface which reacts to the movement of your eyes. There won't be any glasses needed to see the 3D action on the phone. There will be four infrared cameras in the front to track your eyes and using that movement the content on the display will change focus/shift to give an immersive experience which users have said is "very life like."
There will be some tilt gestures to further enhance the usability of the interface. The specs we know are pretty common on a mid-range device, a 4.7-inch 720p display, quad-core Snapdragon chip with 2 GB RAM. But that's the extent of our information on Amazon's phone.
Another important tidbit about the phone is that it might be an AT&T exclusive, but that can be a limited period affair. But don't worry we'll have more on Amazon's smartphone soon. Here's the video showing people's reaction of using it for the first time.
