#3 The pictures you see through this camera is not the same pictures he sees. He has glasses for virtual reality, so he is also a part of virtual reality, and so the balance with him. The inner ear in his head for balance is confused because it is in the "real world" but get sense of the "virtual world".

#(removed comment) Not everyone has sex everyday...

Now add moving air for wind and hot or cold air for climate and a bit of mist spray for oceans, and a few scent cannisters... Better hook up an IV for food because some people will never come out again.

such a thing is called a CAVE: http://de.wikipedia.org/wiki/Cave_Automatic_Virtual_Environment

#4 Correction: He sees the wall as we see it. However because we look at it from an angle we can see the contours of the wall. But from his point of view he can't see the walls because the projectors process the angle seamlessly so he doesn't notice the contours of the wall. He's just wearing regular 3D glasses you would get for a 3D HD TV. If you look on the footage on the wall you'll see that for us it looks like blurred double vision. But for him it pops out like it would at an iMax movie.

Looks like bloody skyrim ! #8 They dont look like 3dtv glasses more like regular 3d glasses (like in a movie theatre) the polarized kind , but still id love to know how they come up with $600,000 figure for that .....

Now a rollercoaster video

Is it possible for him to walk further with such a small platform?

#11 the next version is bigger at the inside then the outside.
