Sony Unveils 'Spatial Reality Display' with Eye-Tracking for Glasses-Free 3D

Cool, but in my opinion, not nearly as impressive as they're making it out to be. It uses eye tracking to give a single person a unique 3d point of view. That's nice for 1 person (and it's quite old tech). Looking Glass is far more impressive and revolutionary in this area[0], as it's not limited by a single person's view. 0. https://www.youtube.com/watch?v=E8pZlI2WM_Q https://www.youtube.com/watch?v=E8pZlI2WM_Q

  There's also https://www.lume-pad.com/ https://www.lume-pad.com/ which I'd love to try out but can't drop a grand on. I have access to a looking glass (the smallest one) and it's quite fun - especially when paired with a Leap Motion for hand tracking. I had the pleasure of demoing it to William Latham who adapted his work for it. ( http://latham-mutator.com/ http://latham-mutator.com/ ) I ported one of my proc gen demos to it and it's in their store - but I don't think you can link to it. The repo is here: https://github.com/IxxyXR/Polyhydra-upm https://github.com/IxxyXR/Polyhydra-upm ( and https://github.com/IxxyXR/Polyhydra https://github.com/IxxyXR/Polyhydra )

  They said it has lenticular lenses and stereoscopy.

What's interesting about this is that the tech has been proven dating back all the way to 2007 [1] and also re-implemented by enthusiasts many times over the years with better eye tracking via CV. What Sony has done here is refine it and package it in a way that's nice for end users. Personally, I'd like to see this implemented more cheaply in larger displays to act as virtual windows for indoor environments, like [2] from 2010, but with 3D video/rendering.

  From what I understand the display is still stereoscopic so you will see a separate image for each of your eyes. Johnny Lee's demo was just a regular image with view-tracked parallax. It looks really impressive in a 2D video demo, but you'd immediately notice there's no depth if you saw it in person.

  I was hoping the first link would be Johnny Lee... He was a true pioneer and hacker in this space.

Other than the resolution being higher, I don't think there's anything new here versus the eye-tracking displays on Nintendo's later 3DS models. That said, it's cool tech, I'm glad to see it actually getting used. I'm one of the few who loves 3D stuff (including the 3DS).

It’s the same AR tech except you move your head instead of your phone. At the end you still gonna need glasses to have the best experience

So they way I understand it there’s no way for stereoscopic? (Two eyes see different things) with this technology? So not fully 3D, just viewpoint adjusted to viewers position?

  FTA: > A micro optical lens is layered on top of a 15.6-inch, 4K LCD display, which divides the image into the left and right eyes allowing for stereoscopic viewing.
