I spent all of last night reading about holographic displays.

[No, I do not mean volumetric displays. I mean a display where you 
compute the interference patterns of an optical wavefront, then use some 
kind of display device to produce that pattern.]

The big plus with this is that objects at different distances have 
different focal depths - exactly like they do in the real world. The 
machine basically generates the same light rays that the real object 
would, so your eyes can respond to it the way they normally do already. 
No weird glasses required. Multiple viewers possible. Etc.

The big downside is... you need an *insane* pixel pitch. And then you 
need a small supercomputer if you want to draw this stuff in realtime.

I did see a demo of a commercial offering which is supposed to be coming 
to market soon - but it uses eye-tracking to slash the amount of 
processing power required. (I.e., it won't actually work in the real 
world and so will never be commercially viable.)
