Since a long time, Amazon is rumored developing a smartphone, following the success of Kindle Fire tablet. The latest rumor said that Amazon smartphone may be equipped 3D screen, like HTC Evo 3D and LG Optimus 3D, but it has a more sophisticated technology called eye-tracking.
According to the Wall Street Journal, Amazon is working on two different smartphones. Smartphone with 3D screen is a more expensive phone. With the new 3D technology, users not only can navigate the phone with eye tracking technology (such as Smart Scroll feature on the Samsung Galaxy S4), but this technology also helps the phone to maximize 3D view according to user’s eyes position.
The device is still in the prototype testing phase. Besides smartphones, WSJ also mentions that Amazon is working on a cloud-based audio player. According to the source, the audio player will be revealed in the next few months.
