"How many cameras would it take to get that hologram effect, and you can't do it with conventional cameras you have today," Llamas said. "Yes, I'd love to exchange holograms on my smartphone with my wife, but that would mean you would have to be surrounded by cameras."
Perhaps Amazon is working to produce holograms with special software that lessens the need for cameras. But, said Llamas: "I'm not looking at 3D holograms coming any time soon.... It sounds cool, like what we've seen in Star Wars movies, but it also sounds like neat technology on paper."
If an Amazon's 3D smartphone uses retina tracking, as reported, analysts wondered how different that technology would be from Samsung's eye-tracking capability called Smart Track in the now-available Galaxy S4. Smart Track is used to pause a video when a user looks away from the phone.
