For games I can see fatigue from having the head set on as a plus, in first person war games, fatige would I think add to "presence". But for learning applications fatigue would be a negitive issue. The sony looks to be thiner and lighter. But the oculus looks more durable. Not likely that these are the real final designs for the sets, but something for us to look at. And not too bad looking!
I have not read or seen a presentation on the Oculus yet. But in the sony presentation the development patners, among others, were UDK and Autodesk, and Epic/unreal. I am curious if those softs will have to have a big upgrade to meet the needs of VR. I don't know game programing, but the video in the OP more than suggested a lot of changes are needed in the ways that games are made.
That video was just a few months ago. So, I guess I will be waiting a good long while before this thing is in the stores?
Hey, were you guys talking about a TG community get together? Maybe you will get to do it in VR

I would attend if I could come as a bear with a negative disposition looking face, and wearing a hawaiian button up shirt. But not an ugly shirt, a nice one.
