Amazon is developing smartphone with 3D screen

May 10, 2013 Inc. is developing a high-end smartphone featuring a screen that allows for three-dimensional images without glasses, The Wall Street Journal reports.

Using retina-tracking technology, images on the smartphone would seem to float above the screen like a hologram and appear three-dimensional at all angles, and users may be able to navigate through content using just their eyes, according to sources,

With smartphones, Amazon could collect new data on its users through maps, phone calls and app downloads, and offer them shopping recommendations. There is also the potential for new services like mobile payments.
