Anyone else notice when you play Guitar Hero and then look away from the fret board, whatever your looking at seems to be moving too.

Me and my housemate were trying to work out what it's called! I guess it's some form of motion sickness or something..

Anyone else get it? I wonder if they'll start putting a health warning on the future GH's? -_-

I doubt it would qualify as motion sickness, unless it actually made you sick.

Based on my extensive medical knowledge (gained from querying wikipedia for a few minutes), seems like it could be a form of nystagmus? I've always thought of it as the same effect where if you spin in one direction long enough, your eyes get accustomed to trying to always scroll in the direction of your spin and keep the world centered. When you stop spinning, your eyes keep tracking in the direction of the spin for a second. The fastest way to counter it, of course, being to spin the opposite direction.

My friends and I all noticed it after playing way too much Guitar Hero when it first came out. You'd finish a song and everything seemed to be crawling upward.

Given that the effects aren't lasting, I doubt we'll see a warning anytime soon.

Though, I think it would be absolutely hilarious if they put a faux warning into one of the loading screen bumps... "If after playing several songs, you notice that your visual focus is moving involuntarily, seek medical attention immediately. You've been rocking out too hard."

It's the same thing (only with motion) as we all experience with respect to our eye lense. The image projected through the lense of our eye is upside down, but after a little while we realized that everybody's heads' aren't pointing down, they are pointing up, and our mind flipped it. You can even wear glasses or contacts that will flip what we see upside down, and we will soon naturally adjust to it.

It is the same reaason this optical illusion works http://www.eyetricks.com/pinwheel.htm But yeah, it is really just the body adusting to continual stimuli until it accepts it as the norm. Then in it's absence it has to re-adjust. It is sort of a visual withdraw.
