Yes, that's the same 3D that fell flat on its mobile face two years ago despite the best efforts of LG and HTC, never to be heard from again. Or so we thought.
The WSJ's sources reckon one of Amazon's new breed of smartphones will feature a screen that allows for glasses-free 3D viewing from any angle. A built-in retina tracker will “float” images above the screen's surface relative to your viewing position and creating the 3D effect.
The same tracking tech will apparently also enable users to navigate through content using just their eyes, the sources claim.
All that sounds fair enough in theory, but then it also did two years ago when LG launched the Optimus 3D and we all know what happened then.
In reality, it's about how well Amazon executes it all, and what else it brings to the table in support. And even then, will it be enough to drive 3D back into our mobile consciousness again? I have my doubts, but we'll have to wait and see.
Sadly, we still have no idea when, where and for how much Amazon's smartphones will be available.
