James Cameron Wants Glasses-Free 3D For His AVATAR Sequels

This past Friday night, Avatar director James Cameron accepted honorary membership into the Society of Motion Picture and Television Engineers, and while collecting his membership he said something very interesting about his plans for Avatars 2 through (TBD).

As quoted by IndieWire:

“I’m going to push. Not only for better tools, workflow, high dynamic range (HDR) and high frame rates (HFR) — the things we are working toward. I’m still very bullish on 3D, but we need brighter projection, and ultimately I think it can happen — with no glasses. We’ll get there.”

Higher dynamic range, higher frame rates, brighter projection - yes, yes, that all sounds likely. Glasses-free 3D strikes me as something else entirely, and I'm curious to learn how such a thing is even possible. Right now I'm thinking of the frantic efforts theater chains made to accommodate the first Avatar's 3D rollout, along with the troubles The Hateful Eight's 70mm release experienced last year. Incorporating a new technology - especially something like theater-wide, glasses-free 3D, which sounds like a Black Mirror episode waiting to happen - is never easy on theaters, and this plan sounds very ambitious, indeed.

What do you guys think? Anyone have any insight into how this process would work, or what'd be necessary to pull it off? Explain like I'm five (I'm actually six and three-quarters, but very stupid for my age).
