Zach Epstein apparently has some details (and images) of the forthcoming Amazon smartphone:
The device houses an additional four front-facing cameras that work with other sensors to facilitate the software’s 3D effects. One source tells us these four cameras, which are situated in each of the four corners on the face of the phone, are low-power infrared cameras.
The device’s extra cameras are used to track the position of the user’s face and eyes in relation to the phone’s display. This allows Amazon’s software to make constant adjustments to the positioning of on-screen elements, altering the perspective of visuals on the screen.
The result is a 3D experience without the need for 3D glasses or a parallax barrier in front the LCD panel like the solutions used by the Nintendo 3DS portable video game console and HTC’s EVO 3D smartphone from 2011.
The question you have to ask is: at the end of the day, does such a feature make for a truly better user experience? Or is it just a novelty trying to mask itself as a differentiating feature? Or worse, does it actually make the device harder to use?
Yes, the iPhone has a “parallax” effect with iOS 7. But Apple doesn’t shy away from it being purely ornamental. And, by the way, a lot of people hate that feature.
The Amazon Phone need only be an Amazon Prime Phone, not some weird, novelty-laden thing.
