New permits which could be for the Star Wars hotel showing how the windows may work to give the impression that you're in space.
Source: https://wdwnt.com/2018/06/disney-patents-a-multiplane-screen-which-could-be-used-for-star-wars-hotel-windows/This “multiplane” screen uses a similar premise that the Multiplane camera, with multiple transparent displays showing different parts of the same image/video. This creates a sense of depth that can fool the viewer into thinking the images displayed on the screen are farther away than they actually are.
A screen like this could be used as a “fake window’ at the upcoming Star Wars Hotel or the upcoming Space Restaurant at Epcot. Users would think that the screen is actually a window looking out into the depths of space, with figures or objects moving around in a ‘3d space”.
