Sony To Launch 3D TVs By Late 2010
eldavojohn writes "The Financial Times is reporting that Sony is announcing 3D TVs for late 2010 at the IFA technology trade show in Berlin. It's another glasses-based technology with "active shutter" being employed (the same stuff teased at CES as well as employed on NVIDIA's glasses). Expect to see 3D Bravia television sets, Vaio laptops, PS3s and Blu-ray disc players compatible with this technology."
I refuse sitting in my living room wearing those nasty 3D-glasses. I'll wait untill Philips opens up its WOWvx department again. I've seen this live and my initial reaction was, well, WOW!
Unless I can move my head to look around something, it's not 3D. If they want to call it 'stereo' TV, that's fine, but it's not 3D.
Well even a hologram goes away when you move past the film. What you mean is you want the image to change depending on your position in the room up to a point (where you are behind the hologram).
And indeed some TVs can do this. the ones with linticular lenses in principle can offer different views to different parts of the room. the stero headsets however don't.
Some drink at the fountain of knowledge. Others just gargle.
> It's a binocular world out there...
It really isn't. Binocular stereopsis is not the most important depth cue that human vision uses, it's just a fairly compelling one that's easy to produce mechanically. Real-world vision uses a combination of relative size, parallax and relative motion, illumination, focus, and binocular cues to figure out depth information. There are one-eyed folks out there with excellent depth perception, and two-eyed folks with poor depth perception. Almost all of the depth action is visual-cortex post-processing.
One of the causes of eyestrain from typical binocular 3D systems is that the images mix up the binocular and focal cues -- the binocular info says that the stuff is a few meters in front of you, but the focal cue says it's all in the same plane.
I personally seem to be sensitive to the focal cue, for some reason -- I seem to get full-on migraines from ViewMaster[tm]-style binocular 3D viewers, and noticeable eyestrain from desktop-scale 3D systems, but can watch theatrical 3D movies comfortably, which I think is due to the differing screen sizes and distances.

Because you need a screen that will reflect the light back in a polarized fashion. In film terms, you're talking about a screen with silver crystals in it for reflectivity. But those screens are enormously fragile - which is part of why 3-D keeps flopping over in theaters - if one person throws their drink at the screen, or even touches it, the screen is wrecked for good and needs to be replaced.
That's not technology suitable for home usage. Which is why home systems have always been based on field sequential systems of 3-D.
