That bit in Half-Life 2? Where you have to cross a jacked up bridge, disable a force-field, and then cross back?
Not so fun in 3D. Especially not when you fall.
Edit: Mostly just the sensation of something rapidly accelerating towards your face. Even without the other two, it’s enough to trigger a fairly decent reflexive reaction.
I’m lucky enough that I don’t generally suffer nausea or motion sickness, but I could see it happening for some. Same goes for fear - despite a fairly healthy fear of heights, I can’t say I’ve felt that entirely when using a Rift. I have felt a moment of brief weirdness when experimenting with infinite projection matrices, but that only lasted until I didn’t actually fall into the perceived infinite void.
That said… A lot of it seems to tie into how well your body handles conflicting sensations between your visual and vestibular system. A lot of people are reporting things like the loading screens being really nauseating because it is a static screen, and if you turn your head the view doesn’t shift whereas your other senses are telling you it should. This also seems to be one of the leading causes of nausea for most people aside from the actual steroscopic bits being misconfigured.
Like I said, it generally doesn’t effect me. I have noticed that the sensation it causes is significantly more pronounced if you are standing up, though.
The new TF2 comic is glorious, as always.
“If you see two numbers but they’re both the same and you have to squint to read them, you have synesthesia, colorblindness, diplopia, and myopia.”
That moment when you start to think that Randall Munroe has just decided to troll everyone…
For reference, I can’t see anything in it. Just numbers. So many numbers.
