Innovision HoloAD Creates Movie-Like Holograms

Looking at it more closely (I think you can almost see the projected image at the top of the overhanging bit in some frames of the videos), it looks like they are pre-distorting the 2D image so that it projects correctly to an artificial image plane _inside_ the box. I think you still only have one viewing angle per piece of glass though, and I'm almost 100% (without seeing this first-hand...) you won't get binocular disparity (or stereoscopic viewing - different perspective into each eye - like the Avatar film with polarized glasses, or the old red/blue filtered glasses).

ah fair play man, opinions are opinions - it just seems you were raking on anyone that liked what they saw in this tech that isn't true 3D, sorry.

I was thinking the vid I linked gave a much more solid image showing much better potential of uses whereas the given one looked a bit "weak"
(there was a real object in this articles vid too - the phone)

I see what you are saying about the down projected image which does seem to be how it works... seems a Very simple technology, if you can even call it that!

Still strange how the "source" of the image appears so stationary to the physical object in the tank - this articles video shows that better that the fish one even.

Would love to have a closer look in person is where I think I will leave this at.

No worries - if I could revert the thumbs thing I would, now that you've shamed me! Yes, I apologise - your link did indeed give a better view, and yes, after I posted the comment I realised the phone was in the first image: what I meant was that in your example, the image is projected _inside_ a real object - which tricks the eye and looks better. What you said 😉

Notice how in the videos, they use spinning animations... if it had been a static image, you may have seen the problem. You can also see the artificial image plane in some videos, where there's some colour bleed across the whole plane.

Don't get me wrong, it's not that I don't like this tech - I think it's a very polished, funky, eye-catching demo - just wish they didn't misrepresent it as 3D! (A term used a bit too loosely these days; but with the advent of 3D TVs - polarised or somesuch - coming to people's homes soon, everyone will know some level of 3D - 2.25D at least ;o)

Still strange how the "source" of the image appears so stationary to the physical object in the tank

Think about a lady-friend putting makeup on in front of a mirror (and standing still, close to it). Now as you walk behind her, left to right, you can see that her image (which appears _behind_ the mirror - her reflection) is effectively static in the reflected space, IYSWIM. (Apologies for the analogy: any object will do!) Replace the mirror with partially reflecting glass, and stick a real object behind the glass - Bob's yer uncle!

Yep - pretty sure this is similar principle to those auto-cues you can get that look transparent and have the speech text back-projected onto it. I'm sure I've seen Obama using one.

You could maybe experiment at home using some partially reflective material (coat a piece of glass with something) - whatever - and then place a bright projection screen at the top (with one of those pocket mini-projectors behind it). Fairly simple maths to distort the image to look like the reflection is coming from a static plane behind the glass... Probably some kind of trapezoidal distortion if you think about it.

Still impressive demo though... (Even if it is smoke and mirrors - without the smoke...)

Good input, together we learn more

Well.... we're getting there I guess.
