What if you rotate the camera slightly while you move? By the time you reach the end of the physical room, the camera is facing the opposite direction in virtual room and you have to turn around.

They've done similar things along with other tricks, like changing the layout of the room when your back is turned to simulate large spaces in small rooms.

For 'redirected walking', you need a lot of room because you can only bend a little. The Void has done it and researchers have, but they usually have warehouse-like spaces. It won't work in a normal 3m^2 sort of residential room, which is why you need gimmicks like teleporting or omni-treadmills.

if it's small enough that user won't notice, you'd still need a big open space. Otherwise it's obvious and obnoxious. There was some games where once you got close to a wall, you could spin in place and the world would keep up with you, but this means you can't have any kind of fight or escape scenes in your game.

It might be obvious, but the user could probably get used to it and learn to live with it.

For the other idea, the game could pause during rotations. Would be annoying, but it wouldn't destroy the game mechanics.

No solution is going to be perfect. I think people interested in this will probably have to do it outdoors, or at some public space.

Just that, say you play one of the survival horror games that people are waiting for to hit VR, you get jump scared and have to run away from the monster and you just blow straigh into a wall. unless of course it starts to show the turning thing way before you a wall (like 2 meters away) which would mean you have to have big room to play in.

It would be worth a try. My bet is that the user vomits or falls down.
