Slowmotion in VR?

You can do "bullet time"... just without slowing the VR driver. So they get to be Neo/MaxPayne while everything else is slow.

Slowing the player... requires that any input controlling their avatar is not 1:1 for VR:Reality. So if you're still using a game controller for movement... sure. But if they have a virtual hand, or walking/steps are interpreted into VR, then no... unless you ship some kind of drug and injector... okay, that's getting silly.

Well, I suppose if you also had haptic feedback to alert the user to "going too fast" and having some penalty (or just a limit on how much their avatar can accommodate, resulting in "avatar-lag"), that could work, depending on the desired gameplay. J.S. Joust (http://www.jsjoust.com/) is all about moving slow. :)

Slow-motion can look very cool in 3D, just see the recent Dredd movie (which got mixed reviews, but I loved it). There were some really amazing slow-motion shots in that film.

For VR I think it's fine provided the user is still in full control. I am not sure how that would work if you did the Max Payne style jumping to the side thing. Might be cool, might be disorienting. Not sure. This is something we will have to try and experiment with.
