The Magic Leap is rumoured to be able to create pure black: "Such may be used to cancel light from the planar waveguides with respect to light from the background or real world, in some respects similar to noise canceling headphones." http://gpuofthebrain.com/blog/2016/7/22/how-magic-leap-will-work http://gpuofthebrain.com/blog/2016/7/22/how-magic-leap-will-...

Realize, that site is pure speculation and nothing has been shown or demonstrated by ML or otherwise that can "display black." In theory it's possible to build a standing wave on the retina, but to do it with pixel precision with a vrd/fsd is beyond difficult compounded worse by form factor. I disagree with the article that rendering black is necessary for wide consumer adoption of AR.

  What makes you disagree with it? I haven't re-read this post from Abrash since it was written (so I don't remember the arguments), but I think telling us more about why you disagree can give valuable input to those of us who are not in the field. :)

    To be clear his definition of Hard AR is different from consumer adoption. So really my statement should say "I don't think we need 'Hard AR'" for AR to win with consumers. I disagree with it based on my interactions with naiive (not an epithet) consumers who are playing in AR. They are excited enough about HMD AR when shown that shadow casting and an AR version of "presence" isn't as much of a consideration whether they would adopt or not. It comes down to "does this provide value." Shadows create realism and people are flexible with realism. That said, "casting shadows" would be a huge benefit and I think it will get there eventually but there isn't a roadmap to it yet.
