Samsung says 3D not to view 3D while drunk, tired or pregnant?

What the hell?

So fine, you’re up watching TV and you’re not drinking. You also shouldn’t be too tired, according to Samsung. The warning strictly says that those who are sleep deprived should stay away from 3D. The same goes with the elderly and pregnant women. Why? Samsung doesn’t say.

And of course, Samsung recommends that you consult a medical specialist immediately if you start to feel lightheaded, dizzy, nauseated, or disoriented while watching content in 3D.

From Samsung:

Even those without a personal or family history of epilepsy or stroke may have an undiagnosed condition that can cause photosensitive epileptic seizures.

Viewing 3D television may also cause motion sickness, perceptual after effects, disorientation, eye strain and decreased postural stability. It is recommended that users take frequent breaks to lessen the potential of these effects. If your eyes show signs of fatigue or dryness or if you have any of the above symptoms, immediately discontinue use of this device and do not resume using it for at least thirty minutes after the symptoms have subsided.

I just talked with a friend yesterday who checked out a Sammy 3D system. He says it was really cool. While he didn't like that he had to put the glasses over his existing prescription glasses, his biggest complaint by far was the slight nausea he felt afterward. He sort of described it as being dizzy, like having just come off a roller coaster . . . But, he genuinely enjoyed the 3D experience.

My girlfriend said the same thing when we were watching Coraline and that is just a two-field deal. I don't think 3D is really ready for the consumer market with the current technology.

Drunk, tired or pregnant?

Funny, it seems like the first two conditions tend to lead to the third.

Dunno if it's just me but not having perfect vision seems to detract from the 3D effect. I tend to have difficulty focusing and invariably wind up with a headache.

For an erection lasting longer than 4 hours, you should also see your doctor.

I would tend to think watching your drunk buddies watch a movie in 3D would be hilarious! But that is just me...

I know why Samsung put the warning out there: Lawyers.

Someone will have been drinking and watcing 3D, got dizzy, puked on grandma, who then sliped on the puke and hit her head on some object like a coffee table, is rushed to the hospital where she never recovers. Hence...Samsung killed grandma.

BMX and I were one of the first to checkout Sony's 3D demo - you can find post here....
Basically active shutter glasses as they are implemented now - s#ck @ss..
Shutter flicker is way to noticeable and can cause all the issue described earlier.
Some people maybe affected less (me) or more (my manager, which after watching only 10mins or less complained about nausea and headache)

Movie Theaters 3D works very differently and don't require active shutter glasses (which cost btw: $150-200 each)

What I want to know is why oh why can't the polarized Imax 3D or RealD 3D that is used in the theaters be used at home? I have never heard this explained. Why do they always convert them to Red/green anaglyph when they put them on blu-ray or DVD?

ps. Anyone wanting some better 3D glasses you can go here.

From Samsung:

Being drunk, tired and pregnant are all conditions that lower seizure threshold. Seizure threshold is also lower in children and the elderly. It is highest is midlife.

I think this will be the tip of the iceberg, and suspect this is a busted flush.

Don't forget if you do get a seizure watching this daft system, then you will loose your drivers license for a period of time. This will vary from state to state.

Also if you do get a seizure induced by this daft set up, you will require a medical seizure work up.

I would be really careful exposing your family to this technology, especially children and older adults.

Remember pulsed light photic stimulation is used to lower seizure threshold during EEG recordings.

That kinda rules out 90% of us....just sayin

Its the nature of how a cinema works - they use a projector where either in the case of RealD 3D, a special projector projects circularly polarised light, alternating the polarisation direction 144 times a second and the glasses blocking out opposing polarisations. A sliver screen is needed to reflect the polarised light correctly. The use of circularly polarised light lets you move your head without losing the image.

With Dolby 3D however, a filter wheel is placed in front of the projection lens which changes the wavelengths of the RGB wavelengths with separate colours being seen by each eye giving a 3D effect when wearing the special glasses. The glasses have filters in them that stop the wrong wavelengths entering the wrong eye. The advantage of this is that no silver screen is needed.

The reason that Polarisation systems are not used with DVD's or Blurays is because LCDs use polarisation to control how pixels are presented and as so using a system like ReadD 3D would mess it up and plus there is no sliver screen to accurately reflect the proper polarisations as the image is coming head on towards you, not behind you.
So active shutter glasses are used instead in newer 3D TV's where a frame from each of the 2 cameras is shown alternately with the TV or graphics card syncing the shutter in each glasses frame to open and shut alternately with each alternating image. To maintain the proper FPS its shown at double the usual FPS as only every other frame is shown so its at 48 FPS in IMAX for instance but its actually only seen as 24.

IMAX 3D can work with either the older linear polarising systems or with active shutter glasses.

Dolby 3D could work with TV but as its quite new there's not very much information about it or if it could be used with TV. I don't see why the TV could not be programmed to change the wavelengths of the colours it outputs or incorporate a colour filter wheel that could be used with the glasses.

Hope this explains why
