I think that is only for demonstration of the refresh rate and colors. I can imagine it being used to "place" the room stationary in specific places. Like to watch animals in africa or fish underwater. Or on a mountain for the view.
Ahh amazing, thank you! I went searching for other videos but couldn't find any. Somehow didn't occur to me that the objects on the ceiling in OP's video, with the exception of the speakers, were images on a video wall too :). Explains the weird way it looks!
this is definitely a render but Hughes Research Labs in Malibu had a room like this in the early 90s, they called it the Cave, using projectors synced up to several computers. meant for one user at a time.
Disneyland Anaheim had a giant room circled by projectors in the 1980s where visitors would stand while holding a handrail and they showed river rafting videos that weren't as crazy as this.
VR caves are still a thing. It's also the technique used for virtual production, with the backgrounds rendered in realtime in Unreal Engine, trackers on the camera for positional data, or camera on a robot arm which negates the need for trackers. It's very cool tech that opens up a lot of possibilities that would be prohibitively expensive to shoot for real.
Interesting! The university I attended had a similar room using projectors, but it was never as impressive as this. They did have it rigged to play Doom, though!
