I wonder if this patent — or these types of technologies — might enable remote learners to select/control more of their preferred viewing angles?!

Apple Seeks Patent For AR/VR Video Recording With Multi-angle Playback — from uploadvr.com by Jeremy Horwitz

Excerpt (emphasis DSC):

If you’ve watched YouTube streams of conventional 2D videos — such as commentaries on games, TV shows, movies, or trailers — you know that the streams are visually flat: video of the content, sometimes with a person’s face superimposed in the corner for added discussion. But Apple appears set to change that paradigm for augmented and virtual reality streaming. A just-published patent application reveals that it’s been working on compositing multiple streams in a way that could let AR and VR viewers watch streamed content from their choice of angles.
