       | getting solutions to the most basic pain-points.
       | 
       | For me, the problem with video-calling isn't the image-quality.
       | It's all the much more mundane technological problems - high
       | latency, lag-spikes caused by bad ISPs, failed noise-cancellation
       | for people who don't use headsets for audio, bad wifi routers
       | cutting out, etc.
       | 
       | First thing I did when I realized we were going to be WFH long-
       | term was buy myself a $100 gaming headset. Next thing I did was
       | get all my home computer stations wired with Cat 6.
       | 
       | That stuff is far more fundamental and far less interesting than
       | 3D telepresence, but it's the real unsexy problem that so many
       | people are suffering through this pandemic.
       | 
       | Even simple things like latency make simple, natural reactions
       | agonizing. Talkcover and crosstalk is incessent and I've
       | developed a filthy habit of just talking over people because
       | otherwise it's a solid 20 seconds of "you go no you go" caused by
       | awful latency. I've had to defuse angry reactions by co-workers
       | who feel they're being interrupted by other co-workers and
       | explain to them that the latency makes interruptions feel worse
       | than they are.
       | 
       | I've tried to push friends to join me on my private Mumble server
       | where the latency is near-nil and the call-quality is excellent,
       | but there's always one person who doesn't have a working headset
       | and wants to just use a laptop or tablet mic with no feedback-
       | cancelling that destroys the conversation through echos (plus
       | Mumble's auth system is needlessly bewildering).
       | 
       | Then with video, problems are similar but less impactful - cheap
       | cameras, poor lighting, compression artifacts, poor sync with the
       | audio, etc. And it's infuriating because every person has a
       | wonderfully powerful camera in their pocket _right now_ - and
       | there 's software to connect them but it's just too tricky for
       | most people.
       | 
       | Good on Google for taking an interest in the subject, but I feel
       | like they're decorating the apex of the technological pyramid
       | while most people are pushing stones around at the bottom.

         | I've been very curious about this too.
         | 
         | I believe there are two basic approaches.
         | 
         | The first is "lenticular lenses" -- the same technology used to
         | make those shiny postcards that change depending on what angle
         | you tilt them at.
         | 
         | Here's a site with an example GIF and kinda explains how it
         | works: https://setosa.io/blog/2014/07/07/lenticular/
         | 
         | Normally, the lenticular lens is glued directly onto a printed
         | sheet of paper, but you can instead glue it onto a _screen_,
         | which lets you change the pixels underneath. There are a lot of
         | challenges here; for example, the pixels are usually located a
         | bit behind the glass, so the standard lenses used for printing
         | won't focus perfectly on a screen.
         | 
         | There's also another, simpler approach called "parallax
         | barrier". This is what the 3DS used. Instead of using lenses to
         | bend light, it _blocks_ the light coming out of certain pixels
         | at certain angles. It's basically just an opaque sheet with
         | periodic slits (the 3DS uses an LCD, so that 3D can be turned
         | off by becoming transparent). Before I found a video of someone
         | making one themselves using an iPhone and transparency sheets,
         | but I can't find it at the moment...
         | 
         | 3DS parallax barrier:

         | Diagram from Wikipedia article:
         | https://en.wikipedia.org/wiki/Parallax_barrier#/media/File:P...
         | 
         | A big disadvantage of parallax-barrier is that you end up
         | blocking a lot of the screen, making the image darker.
         | 
         | Supposedly you can combine the two approaches to reduce the
         | darkness.
         | 
         | https://www.youtube.com/watch?v=yetX2C3AdCI
         | 
         | There are probably even more tricks involved, and this is all a
         | lot easier-said-than-done.
         | 
         | Here's a project that uses an LCD to make a dynamic parallax-
         | barrier, that increases brightness by skipping the barriers
         | wherever they don't matter:

         | https://www.youtube.com/watch?v=YrRnURU1W3E
         | 
         | Tangent: There's also been some attempts to do _the reverse_,
         | and use distorted lenses in front of a camera to recover a 3D
         | scene using only a single camera:

               | I think it's different this time. It's not just it being
               | 3D, but the merging of new generations of light field
               | cameras, face/eye tracking, powerful ML algorithms, low
               | latency networks and revolutionary displays is miles
               | ahead of previous attempts. You can't just compare this
               | to the ViewMaster and last century VR. The improvements
               | here are much more substantial, and if they can make it
