Amazon has been rumored to be releasing a smartphone for years and analysts have long speculated about how the e-commerce giant might integrate its current business into a smartphone.

One of the differentiating features analysts expect the device to have is a 3-D display, which would enable 3-D gesture tracking. Such a display would help the company stand out in an already crowded smartphone market.

Apple is also rumored to be working on a device with such technology and Intel's CEO Brian Krzanich told CNBC earlier this year his company's partners are already integrating its 3-D camera technology into mobile devices.
