3dTV is old tech

davester

I saw 3dTV (without glasses) over 6 yrs ago mounted on a wall in a Bangkok Department store, they ran credit card and such adverts from it. They wasn't there promoting the TV brand, they was on the wall the same as we see the big tvs at waiting rooms of banks and the like, just these were 3D. The credit card rotated and appeared to come out of the screen.

So I am confused why so much hype and excitement about them now ,when to me they have been around for over 6 yrs?

Their have been a few "3D" systems in the past.

There was even a "3D" arcade game that didn't need glasses, using curved reflective glass screens.

The point is that that screen you saw probably cost in the region of £80,000 to £100,000 each.
Like most tech it starts in asia many years before it gets affordable for the general public in Europe and the US.

because the electronics giants want you to throw away your brand new plasma/LCD and buy into the next 'big thing'

I think its called 'sponging people for as much as they can'

It looked like any normal LCD tv on the ouside, you only knew it was 3D when the ad played, Although its the first time I have got that horrible sickly feeling which is usually associated with VDU strain after a 30hr stint on a game, after 5 seconds. I just hope the new TVs are not the same, I will have to go into comet and see if they make me throw up. PC World makes me ill anyway but thats for other reasons.

Most consumer tech is "old" tech.

The glasses versions were around 10-15 years ago, most Touch screen tech is from the 80s....

Things take time to develop to be marketable I suppose...

No I understand the consumer tech is usually dated, its just how noone talked about 3DTV since the 70s Jaws movie with the red and green glasses, to this insane hype with avatar and the current lot of TVs and was thinking i hope its not the same tech as I saw on these 26 inch flat screens 6 yrs ago, cause I'm sure I'm not the only one that feels sick looking at the screen, and means Electrical stores will have more people throwing up instore.

It could be the tv you looked at. i believe ALL of the 3D tvs exhibit 'crosstalk' between the flickering of the 2 images (Which I completely expected as soon as I heard about how they worked). What this means is that after frame 1 is displayed in the right eye it flicks to frame 2 in the left eye, but due to crosstalk parts of frame 1 are still visible
Things of this nature will create serious headaches and the like after extended viewing

Personally ive no interested in 3D until all this is sorted out (Be at least 2 years off id guess)

(Crosstalks probably the wrong word, more like pixel response time, although crosstalk is highly possible at such high framerates)

3D or true 3D ?, if they want to impress me, when they are able to model the image in all three physical dimensions, I'll begin to take an interest. If I can, from where I'm sitting, look around the scenery / characters just like I can now look around the back of this monitor - I'll begin to take notice of 3D, until that time arrives it's really only [ Emperor's~New~Clothes ] 2D with knobs on.

It's just a Paul Daniels effect, a senses based experience not reproducible in an ordinary home, even in a ' home theatre environment '.

Seeing 3D in a megga cinema where a persons whole field vision [ including the peripheral ] is saturated with images and in addition directional sounds fills other primary senses makes me wonder if it's ever a home based experience - even wearing electric goggles.

N.B.1. I've never seen a 3D TV and N.B.2 I still have (somewhere) an 8/10/? year old ASUS video card complete with 3D glasses that used to plug in to the back of the video card.

Is it just me, but I saw a 3D tv in PC world the other day, and I couldn't see the any 3d images. I also saw a 3d movie at a cinema and only got a slight sensation of a 3d image?

Nb I wear varifocals, does this mean that 3d pictures dont work for me?

Virtually all of the current "3D" systems use technology that's over 100 years old - the principle of showing your two eyes slightly different images to produce the *illusion* of depth.
