Amazon will reportedly use Omron’s Okao Vision face-sensing technology to track the users' heads and enable 3D effects in its upcoming 3D phone, according to a report from TechCrunch.
Face-tracking 3D enables a 3D effect on a normal LCD screen. Four front-facing IR cameras will track the user's head, and along with Omron's technology, will adjust the on-screen objects as the user's perspective changes. Amazon's phone will be able to grab X, Y, and Z coordinates of the user's face for developers to play with. The tech is demonstrated well in this video.
The phone will join Amazon's lineup of Kindle Fire devices, currently the Kindle Fire HD, HDX, and the Kindle Fire TV. Like those devices, the phone is expected to run the Fire OS, a heavily customized fork of Android.
