Wow this seems expensive and bulky compared to a headset with a hi resolution screen a few inches away from the eyes.


It does, except that this technique can, in theory create a holodeck like experience for a group not wearing headsets. That would be better for training and simulation.

For a while I was looking at building a basement with a "picture window" which was really just a view from the floor above ground. "Normal" displays don't simulate a good window experience, a curved display can give a decent simulation if you don't move (and that is what they do in flight sims as you are constrained to your seat), but a light field simulation would really give you the feeling you were looking out of the window directly, even when moving around your point of view.


Even for a single user you need to add head tracking to get a perspective that shifts as you move your head (though that's pretty doable with consumer stuff these days). For a multi-user system I think you need something more like this.

It could be interesting to do multi-user individual-perspective shutter-based 3D, but you'd need to run at a really high framerate and you'd probably have brightness issues as each eye would only be receiving light for some smaller fraction of time.
