Human Eye's Oscillation Rate Determines Smooth Frame Rate

jones_supa writes: It should be safe to conclude that humans can see frame rates greater than 24 fps. The next question is: why do movies at 48 fps look "video-y," and why do movies at 24 fps look "dreamy" and "cinematic." Why are games more realistic at 60 fps than 30 fps? Simon Cooke from Microsoft (Xbox) Advanced Technology Group has an interesting theory to explain this all. Your eyes oscillate a tiny amount, ranging from 70 to 103 Hz (on average 83.68 Hz). So here's the hypothesis: The ocular microtremors wiggle the retina, allowing it to sample at approximately 2x the resolution of the sensors. Showing someone pictures that vary at less than half the rate of the oscillation means we're no longer receiving a signal that changes fast enough to allow the supersampling operation to happen. So we're throwing away a lot of perceived-motion data, and a lot of detail as well. Some of the detail can be restored with temporal antialiasing and simulating real noise, but ideally Cooke suggests going with a high enough frame rate (over 43 fps) and if possible, a high resolution.

    If religious people had any proof, it would no longer be religion.

    Sure it would. Why would the definition of "religion" change? I mean, the real one, not the Dawkins made-up one.

    But, "proof" (clever of you to goalpost-shift this up front to a criteria virtually nothing, including science, can meet, by the way) would be tantamount to worldwide forced conversion. You'd either have to accept it, or go to an asylum for denying basic proven facts. Might you see a reason a God would not want that, particularly in this era of global communication?

    That said, to use reasonable epistemological criteria, here's peer-reviewed evidence. As with most domains, -evidence-, not -proof-, is the intellectually-honest expectation.

    It would be called "science" by people like you, who fail to understand that nothing in science is "proven", it is a collection of models that are always provisional and permanently open to revision based on future data.

    Still, say, one's preferences in art... do you object that those aren't "proven" and therefore aren't "science"--and what do you conclude from that?
