Amazon working on smartphone that renders 3D images: report

Amazon is said to be working on a smartphone that would render 3D images on the screen with the technology not requiring special glasses. The Wall Street Journal, quoted sources as saying the smartphone would have four front-facing cameras that tracked the user's retina to "make some images appear in 3D, similar to a hologram."

The eye-tracking technology would monitor whether the user had moved closer to the screen and automatically zoom into images.

According to the report, the technology might also "manipulate text and images as a person moves the phone."

People who had used the smartphone, said the technology "would be ideal for gaming." The smartphone's software would also be customised to support "very visual games" and designed to render a sense of depth on the flat screen.

According to the report, Amazon had been inviting select app and software developers to hotels to demonstrate the handset in suites protected by security guards, two people familiar with the matter said.
