'Another 3D mobile?

Here's a rumor that has caught many by surprise. The Wall Street Journal says that Amazon is preparing a line of phones. So far, so good. Amazon deployed achieved some success in the U.S. market tablets thanks to its price and its full range of hardware, software and content. Make the jump to mobile would make sense, especially if it makes things easier for operators. Now comes the part that costs digest: at least one of those phones will autoestreoscópica 3D display, meaning you will not need special glasses to see the image a sense of depth, as, for example, the screen of the Nintendo 3DS. At this point gave the impression that the industry is that the 3D-mania had passed its worst phase. Out the marketing budget that remains is more or less is a residual interest in large theaters and virtually forgotten at home. Hollywood As much as it hurts, just not a desired feature by the general public or at least not in its current state. The phone has not lived outside the fever. LG came to put a few years on the market the first phone capable of recording video and taking pictures in 3D with a screen play, but without much success. The problem with this type of display is that the 3D effect is not always good. It depends on the position and distance from where you look and a small twist of the wrist or head can make you lose the sense of depth.  In telephony, however, there is a possibility to improve the quality thanks to the front camera of the device. If you have sufficient resolution and is able to detect where the user's eyes could adjust the screen parallax effect for a continuous feeling in 3D, even on the move. But that "if" is the key to the whole thing. By now the phones that have attempted to use the front camera to try to detect the user's gaze (the newly marketed Samsung Galaxy S4, for example, used to control the movement of a text without hands) have found that it is much more complicated than it looks or what they imply laboratory conditions.
