Reply to: Glasses-less 3D TV...

No. People all over the world have issues with 3D, from headaches to some level of visual impairment.

Pushing ahead with 3D only screens would be akin to only allowing white people to go to the cinema.

That's a crap analogy.

Owing to an unfortunate sight issue I only see in 2d (exciting parking) - I'm concerned that in future all screens will be 3d.

Am I right to be concerned?

I agree. Of course then the 'TV' would be rated on how many people could watch it at once.

It's pretty similar to eye-tracking software used in laser-eye surgery, if TW and I are thinking along the same lines... sort of like Kinect but tracking your eyes so two images can be beamed in directly.

It was the laser generated image on the retina that was disturbing.

I must admit that it was a bit of an "in" joke too.

Alternatively, we can't be far off being able to fire very low powered laser beams into each eye separately, which would do away with the big box and screen altogether. You could even watch two programmes at once.

Yeah but would you want to test the prototype?

If your eyes are 3 inches apart, and you shift 3 inches to the left, does that now mean the image that should have been going to your left eye is going to your right, and vice-versa?

And that would make all the 3D backwards - everything would stick out of the screen when it was meant to be in the distance.

Ugh! It'd be like one of those magiceye pictures from yesteryear where it all goes wrong and crosseyed and the image is inverted.

But, no, it wouldn't matter, you'd still see the right image, your eyes would be seeing the other image but your brain wouldn't know the difference... Have you tried using the stereoscopic glasses back to front at the cinema? It still looks the same.

Sorry, poor explanation on my part.

There are several ways to create a 3D image without the use of glasses... Most involve additional layers of LCD or lenses, to block certain viewing angles so that the alternating picture can reach each eye properly. The downside with this method is that if you shift in your seat whilst watching, you may well lose the 3D image.

10 Stellas.

Promotes the intention but destroys the performance.

What were we talking about again?

[AtW]

How the **** does that work then?

depends on the rate

Yep, the Good Lord saw fit to give you two eyeballs...

[Mich the Tester]

[Churchill]

It was sort of, with the addition of a lenticular sheet.

Yep but with only one display device.

I took MrRobin's description to mean multiple LCD panels in the Z axis.

[scooterscot]

Saw one in IFA electronics consumer show in Berlin last summer, pants really but very interesting technology.
