According to the latest report from the Wall Street Journal, Amazon is working on a new smartphone that will have a 3D display. There have already been a lot of rumors in the past which said that Amazon is working on a new smartphone, but none of them indicated that the new smartphone would have a 3D display.

It has been said that Amazon is working on not one, but two new smartphones. One of these will be a high-end next-gen device that might even surpass smartphones like the Samsung Galaxy S4, Sony Xperia Z and the HTC One. Information provided by unnamed sources indicates that this high end smartphone from Amazon will have a glasses-free 3D display, similar to the concept that was tried out with the Evo 3D smartphone.

Along with a glasses-free 3D display, this new smartphone is also expected to have eye tracking that will allow consumers to control the smartphone using their eye movements, similar to the technology present in the Samsung Galaxy S4 but this one is expected to be at a much higher level.

Another interesting piece of information provided by the sources is that the eye tracking technology in this new smartphone will also be used to enhance the 3D display. Using eye tracking, the device will be able to tell where the users are looking at any given time and refocus the display accordingly. So there will be no need to keep a single correct viewing angle.

Now that you have an idea about what kind of smartphone Amazon might come up with, we have some more interesting news for you. The Wall Street Journal also said that Amazon is working on a lot of other smart devices apart from this 3D display enabled smartphone.

The WSJ says that Amazon might also be working on an audio-only streaming device like an iPod for the cloud, a set-top box and many more. The report said that some of these devices will be revealed in the months to come whereas many others might still have a long way to go.
