The Magic Leap doesn't just dangle one image in front of your eyes, like Microsoft's Hololens. Rather, the Magic Leap projects physically projects several visual layers at different focus distances. If you are looking at something near in the real world, your eye will change focus to look at it, and the "near" projection in the Magic Leap will be in focus, while the "far" projection will go blurry, right along with the "far" in the real world. However, I think Magic Leap has reduced the number of layers down to something like three [edit: two], from the many more layers they were showing before.

in this model there are only two focal planes as far as I know.

It's a multifocal display? That could indeed be a significant competitive advantage. If that's the case though, I don't know why they don't just call it a multifocal display instead of using all this confusing, non-standard terminology like "Dynamic Digital Lightfield".

  My best guess is marketing. Why did Apple call it's video calling FaceTime? It separates them from the competition.

  The name is meaningful and standard to me. I call it a "Light field display" - see https://en.wikipedia.org/wiki/Light_field https://en.wikipedia.org/wiki/Light_field See also the reverse "Light field camera" https://en.wikipedia.org/wiki/Light-field_camera https://en.wikipedia.org/wiki/Light-field_camera The "dynamic" part I don't understand yet - something to do with eye tracking allowing a higher resolution than otherwise would be available? Where's "multifocal display" from as terminology?

    Maybe by "dynamic" they mean it's actually a varifocal display, like the Oculus Half-Dome prototype? https://www.oculus.com/blog/introducing-the-team-behind-half-dome-facebook-reality-labs-varifocal-prototype/ https://www.oculus.com/blog/introducing-the-team-behind-half... As for where I heard the term "multifocal display", I'd recommend checking out Douglas Lanman's talk at SID Display Week, where he goes into detail on a whole bunch of possible solutions to vergence-accommodation conflict in VR headsets: https://www.youtube.com/watch?v=GbRvkS3GDsw https://www.youtube.com/watch?v=GbRvkS3GDsw
