Pepper's Ghost display?
This appears to stack a bunch of displays together, so not pepper's ghost.

#12It would be interesting to find out what the dimensions of this are in voxels. The 2 million voxels makes me think this is based on a 1920x1080 projector.
A graphic on https://www.lookingglassfactory.com/how/ showing the obligatory macbook has its display divided vertically into what looks like 10 slices - so perhaps 1920x108x10?
That would seem plausible as to what the photos on the site represent, but some of the 3d renders use a much higher vertical resolution for the display.
(This is just an educated guess, of course.)

#13I'll start by saying this is a really interesting device, and a very impressive technological feat. However, I have some major criticisms too:
The only advantage I see to this vs. something like HoloLens is that it doesn't require a head mounted display. Unfortunately for this project, that's not as big a barrier for serious companies as they need it to be. In time I think this "advantage" will also dwindle due to shrinking component size, etc.
The price is also considerable - it's about a thousand dollars cheaper than a HoloLens (I'm going to keep going back to HoloLens because to me they're directly comparable.) But the thousand saved also comes with some significant drawbacks:
- The notion of collaboration seems to be non-existent with this device - I don't see them showing how that might work based on their promo clips. Seems to be single user driven.
- It has a back-face. How do you render something like text so that it's readable from all perspectives?
- Control appears to be limited with no standard input. HoloLens tracks the users hands, by comparison.
- Does it have a top on it? At that point, what really separates it from a 3D TV? Seems like you'd only get limited perspective translation.
I'm having trouble coming up with really practical applications for such a device, that wouldn't be better suited by a head mounted personal device. I fully support the effort if they find their niche, but coming from a VR/MR point of view, I can't really see any real advantages. Please enlighten me! I don't mean to be a downer!

It looks like multiple such displays stacked up, for true depth. Each of your eyes will see a slightly different image because it has real parallax, and each person around a display will see from a different angle too.

#15I was hoping to learn a bit more about how it works. They hand-wave about "lightfolding", but what does that mean?

They specifically say that it is not.

"Multiple pepper's ghost displays stacked up" doesn't really make sense. Pepper's ghost requires a lot of space, and it isn't really stackable.

#19Earlier quoted context omitted.
Only one person at a time can use a VR headset, and they can get a bit cumbersome.
Two people can use two VR headsets
Right, but it's the same reason I got a RealD television instead of a shutter frame one. You're not gonna give a roomful of people (especially if they're children) shutter glasses. Too expensive by half. RealD glasses are easy to come by and when the dog eats a pair (or a couple, in my case) it's an inconvenience.
Headsets are great when you're only entertaining yourself. Terrible when you have friends you're entertaining.
