NVIDIA glasses make home computer screen 3D

January 10, 2009 Visitors play a Guitar Hero video game in 3D wearing NVIDIA GeForce 3D Vision glasses

Visitors play a Guitar Hero video game in 3D wearing NVIDIA GeForce 3D Vision glasses at the 2009 International Consumer Electronics Show at the Las Vegas Convention Center January 9 in Las Vegas, Nevada.

NVIDIA wants zombies to reach right out of videogames and virtually grab players by the throats.

    Glasses, be they 3D glasses or safety glasses, never work properly for people who wear prescription lenses, even when they say they do:(. Autostereoscopic or nothing.

    This is just crummy old LCD "shutter" glasses technology. The LCD killed it because their refresh rate was so horrible(50-60 Hz), but now that they're creeping back up into the 120 Hz region it has become somewhat practical again.

    120 Hz is still not very nice; that will give you 60 Hz flicker(because frames are alternated to the left and right eye, with the other eye seeing only black). Ideally you'd want the 160 Hz a decent CRT is capable of; at 80 Hz the flicker is between not noticable and not enough to be terribly annoying for most people.

    Polarizing glasses and displays emitting polarized light(different direction for each eye, e.g. circular left-handed polarized for one eye and circular right-handed polarized for the other) is much better. Since LCDs provide continuous light it wouldn't flicker even at 60 Hz. But this is much more expensive tech.

    My favorite is VRD technology, so much promiss if it can ever be developed.

    "Reality begins at 24 frames per second", which is film speed. Film in theaters is shuttered 2x per frame, for 48hx. This, to cut the slight residual flicker effect.

    Flicker comes from the (lack of) glucose that is secreted to the given rods and cones in the eyes of the given person. Each eye is different. The rods and cones 'fire', which is neurons firing in response to activation via photonic observable light frequencies. Brighter lights cause more neural firing, which DECREASES 'persistence of vision',as the 'slow and continuous glucose feed' to the optical system is used up faster and thus less glucose is there for maintaining the signal impression.

    Flicker then means that it happens when you naturally have less glucose flowing to your optical nerves (rods and cones). This means when you are tired or stressed. If flicker occurs, go to a LESS BRIGHT environment AND/OR display, and be better rested and fed.

    Flicker can also occur in lower empathy people as a direct physical adjunct to their inherent physical design parameters -- but that is yet to be proven. Speculated - but it may be connected. I feel it is, from my observations on the subject. However, it can be confused with 'cranky and low sugar'.

    3-d does work with people who have glasses, but the Contrast Ratio in the instantaneous 'frame specific' sense (within the exact and signal frame) must be as high as possible. This, to get past the contrast issues of the glasses. It must also be of a linear and dynamic consideration that is corrective due to the lower CR (Contrast ratio) create by the glasses.

    Get or use contacts instead to have this work, as that reduces the CR losses from the glass air-interface/interference.

    Sorry NVIDIA...you quietly disabled video mirroring on your driver updates....After finding out after I dropped the cash, I will not be buying your f'n video cards until you put back the options you removed, hello ATI.....

    "Film in theaters is shuttered 2x per frame, for 48hx. This, to cut the slight residual flicker effect."

    I was under the impression that theatre projectors displayed each frame thrice, for a 72 Hz refresh rate.

    "Flicker comes from the (lack of) glucose that is secreted to the given rods and cones in the eyes of the given person. Each eye is different. The rods and cones 'fire', which is neurons firing in response to activation via photonic observable light frequencies. Brighter lights cause more neural firing, which DECREASES 'persistence of vision',as the 'slow and continuous glucose feed' to the optical system is used up faster and thus less glucose is there for maintaining the signal impression."

    So if I want better temporal resolution I should crank up the brightness, go on a fast and stay up late? Good to know, but it doesn't sound all that healthy.

    "Flicker then means that it happens when you naturally have less glucose flowing to your optical nerves (rods and cones). This means when you are tired or stressed. If flicker occurs, go to a LESS BRIGHT environment AND/OR display, and be better rested and fed."

    I doubt that. My critical flicker frequency is around 80 Hz. No amount of staying up late or bad eating habits appears to allow me to see flicker at 85 Hz; I've done quite a bit of that and I ought to have noticed at some point. Not even in the corner of my eye where it is most sensitive.

    The variation in critical flicker frequency with brightness is very easy to notice though.

    I don't like contacts. They hurt. That's why I said that autostereoscopic is the only way to go (ie, hololithic 3D (not holographic, that's different) straight from the screen without 3D glasses or any other aid).
