April 8, 2016. Honestly.
Look up the video which Magic Leap caused to be placed on YouTube in June, 2016:
"Magic Leap Virtual Reality -- Behold The Future"
and this statement appears at 1:55 of the video's 2:35 duration:
"Shot directly through Magic Leap technology on April 8, 2016. No special effects or compositing were used in the creation of this video (except for this text.)"
The wording is explicit. What appears in the video are not simulations contrived "with" Magic Leap technology but an augmented reality viewed "through" that technology.
As the "technology" referred to is the Magic Leap goggles, then on April 8, 2016, a wearer of that device would have seen "through" the goggles' lenses exactly that which is chronicled in the video.
All that was required for that individual's visual experience to be widely shared was a camera to shoot "through" those goggles.
As that was the state-of-play on April 8, 2016, and as the company was so unambiguous in its use of language, one can only wonder why the goggles are still not on sale -- and why, if many thousands of people can see what an individual wearer would've seen all those months ago, there's any need for secrecy (and Non Disclosure Agreements) now?
Pictures of the product exist. Pictures of a wearer exist. That non-enhanced, non-manipulated video exists. The truth is out there. Honestly.
