Deep-learning enables real-time 3D holograms on a smartphone

I saw the whole video, but at the end I didn't see anything on a smartphone.

It is still in research phase.

I watched the video too, and I wonder why they didn't show the screen from multiple view-angles so you get a feel of the 3d effect.

It's a bench top display projecting directly into the camera. Similar to the one presented below, which provides a bit more context about how the display works.

I tried to understand it. But I don't. Is this able to generate 3d images from 2d and automatically projecting it based on the line bounce angle of your eye and screen?

Pleasantly surprised to see this is actually about holograms, and not a volumetric display misusing the term.

Kind of pointless unless you have an actual holographic device.

Better thing is a NERFie with eye-trackers

But, they have an actual holographic device.
