The video game Prey2 features similar technology also called LookingGlass. It has a fairly prominent role in the story line. I wonder if the naming is a coincidence or a nod.

If anything, it's a nod to Looking Glass Studios. Arkane's Prey is intended to be a spiritual successor to System Shock. (I presume that's what you're talking about, even though it's not related to the original 2006 Prey.)

This reminds me of https://www.youtube.com/watch?v=Jd3-eiid-Uw (2007) Johnny Lee's demonstration using head tracking with infrared led's and a wii remote to implement the same thing. Obviously that limits the effect to the individual's head being tracked, but its amazing its been 12 years since that demo and we're still trying to commercialize the same affect.

Looks like 3D inside a tv. It ain’t holographic unless it projects enough for you to touch thru it.

Real holograms don't project from the surface either. Sci-fi "holograms" are a different thing. Please let's remember that holograms are an existing technology and have nothing do to with sci-fi 3D open-air projections.

I have one of the smaller versions of the Looking Glass and it's genuinely like looking into the future. It's a remarkable thing to see live. My main complaint is the low resolution (4k divided into 45 layers).

Bigger size and bigger resolution is a great step up here - I hope they get to continue in that direction!

Earlier quoted context omitted.

Too late for an edit but I was going by what was shown in the video, which very much didn't look it could do that. That said, that's still basically "3D but without glasses", not exactly the Holodeck "hard light" future tech many people think of when they hear "real hologram".

I mean, a real hologram (made using light interference) is also not Holodeck hard light.

Yes, but at least a real hologram creates an actual depth sensation as the eye's focus needs to adapt.

This means 3d impression works even for people with reduced stereoscopic eyesight, and does not create headaches due to a mismatch of scene depth vs. physical display depth.

Such holographic displays do exist, e.g. www.seereal.com (which BTW recently received an investment by Volkswagen).

How does this product change prospects for Magic Leap?

There's overlap between the potential client domains, but this doesn't encroach on the AR domain covered by products like Magic Leap.

And there are legitimate commercial use case for AR - e.g.: automotive manufacturing and building construction.

The biggest impacts to Magic Leap's prospects came from the premature over-hyping of the product as well as microsoft beating them to the punch with the HoloLens.

Projection is entirely impossible. The photon's path has to back-track through the device; this is true regardless of the type of device you're using to make it.

Omni-directional beams of microscopic photon torpedoes could allow images to be projected in front of your hands.

The camera motion makes it look like they're trying to hide something... like the effect only works horizontally, not vertically.

The looking Glass display is horizontal parallax only (HPO). HPO is a common information reduction method in the 3D display world. Most holographic stereograms, all rainbow holograms, and all 3D lenticulars are HPO. Occlusion, horizontal motion parallax and stereoscopic cues are preserved, which are our primary 3D cues. The loss of vertical parallax changes computation from an N squared to N problem. An interactive d…

From back when I researched it, accommodation mismatch is a huge problem for a small (but significant) proportion of the population in terms of nausea or headaches. It's less of a problem for movie-theaters because accomodation is at infinity for the screen itself, so as long as they don't have too much for too long that is much closer to the viewer than the screen, it doesn't cause any issues, but it seems like it would be a major issue for a screen designed to be viewed up close?

The 3D glasses problem doesn't really apply here. With 3D movie glasses, everything is blocked out except for the 3D images. Some people feel queezy when their proprioception and visual input don't match. It's a little like car sickness.

With the screen, they do match, as only what's on the screen is 3D. In that sense, it is like looking at a box with something 3D in it, versus being submersed inside something 3D like with the glasses.

tl;dr With the screen you can move your head around and the world moves with it, so there is no sensory mismatch. But turning your head when going into a 3D warp speed starscape with 3D glasses on might easily cause someone to ralph on the poor sole sitting in front of them.
