Maybe great things will come from this eventually. I doubt that Sony expects to sell a lot of these.

It's a great first step towards commercializing hologram/3-D technology. It's been around for a little while now but I haven't seen any plans to mass manufacture anything until this. Would be great to design something in AutoCad and be able to look at everything in 3-D.

This looks like it's a volumetric display. Volumetric displays work by sweeping a 2D display across a 3D space, and using persistence of vision. For instance, some displays work with a rotating display panel that shows a 'slice' of the 3D image for a particular position. Other volumetric displays work by having a number of "planes" which they can display a 2D picture on. One Japanese design works by generating plasma balls in mid-air by focusing a high power laser at the point in the air where a voxel is required!

As far as commercial designs, there's ones like the Perspecta Volumetric 3D Display-, or DepthCube z1024 or Technest - Displays for 3D Imaging.

The biggest problem is managing the amount of data that's needed to keep the display running. Rather than use pixels, these displays use voxels. It's basically the same idea, but in 3D space rather than 2D space. Graphics cards are really going to need to speed up to manage 3D displays!

For example, the DepthCube manages 15.3 million voxels, which would be similar to running your graphics card at a resolution 5000x2925 pixels. Actuality's display runs at about 116million voxels, which would be similar to running your graphics card at a resolution of 14000x8000!

Sony haven't given the whole resolution of their device. We know that whatever is scanning the display has a resolution of 96 × 128. That doesn't tell us how many slices of 96x128 it can display. If I assume it can manage 90 slices, then it can manage a resolution of 1.1 million voxels (96x128x90)

Voxels as in "volumetric?"

Yup, you're on the right track.

Persistence of vision sounds like cheating to me. But one may well ask: how the hell do you know, c?
Thanks for the assistance, Aedan!

Lots of things use persistence of vision including CRTs, fluorescent tubes (standard and "energy saving" bulbs), cinema, plasma displays and lots more!

Yeah George persisting vision I think its like when I see an amazing looking babe and as I turn my head back I still have her image on my retina ! :rolling:

Followed by a close inspection of a lamp post?

Don't tell me you saw me! :rolling:
