Is it too late to rename these various stereoscopic systems to something other than 'holograms' ? Because they're not holograms. Holograms work by interference and have the property that when cut into pieces each piece is a (dimmer and narrower FOV) copy of the whole. Stereoscopic systems could be called 'stereograms' ?

At least in the case of Microsoft Hololens, the name is somewhat justified because the display tech goes beyond stereoscopy and actually projects a light field using waveguides.

Some details on the tech here:

I have little faith in this company or approach to holograms. Euclideon has shown off their voxel based renderer for years as something that will revolutionize gaming and real-time production as we know it - but it has done no such thing. It's certainly interesting tech. The cheesy, clearly photoshopped teaser images here do nothing to inspire confidence - and based on the technology they described - I don't believe…

I'm still wondering where the money is coming from. I would also like to play around for years with this kind of technology.

As someone with a background in urban planning, these kinds of statements always convince me that nobody knows what urban planning entails.

Funny enough, at community meetings, many planners like to avoid realistic renderings of changes. For example if you want to give people an idea of what sort of size buildings could have under a proposed upzone, you don't want them fixated on the color of the brick facade in the rendering.

I can't really imagine a holographic display helping planning in any real sense beyond getting school kids excited.

I had worked on earlier model of Microsoft surface table. They had the same pitch that these multi user multi touch devices will be used by education and banking systems etc. they don't work simply because its not solving any problem. Why would people go out of their way to learn new ways of designing, developing and communication just so they can share their work in hologram? What does it solve? Until this is answered AR and VR are not going anywhere.

Easy way to tell a faked 3D display: look for imagery lying along a line of sight that doesn't intersect the display medium. For example, the dinosaur's head and the tops of buildings stick out above the display's edges as seen from the viewer's location in the video.

Objects may be in front or behind the display's surface, but the display medium has to lie in front or behind every part of the object.

For all practical purposes, photons travel in straight lines, and require some medium to create or redirect them. It is extremely unlikely that anyone will suddenly discover an easy way to change that fact.

It could be used for that exactly, getting the public interested in new development projects. Not sure it would be worth the cost though.

AR has huge business potential in any job that requires use of both of your hands, especially for tasks where you’re moving around and don’t want to be tied to a monitor.

I agree with you when it comes to jobs that are currently done with monitors on desks.
