In the past, before phones and the Internet, all communication was face-to-face. Now, most of it is digital, via emails and messaging services. If people were to start using virtual reality, it would almost come full circle.

VR is going to be defined by the content that is designed explicitly for virtual reality.

Once you have perfect virtual reality, what else are you supposed to perfect?

I was interested in virtual reality for several years even before working at USC, it wasn't an interest that started there at all. In fact, when I started working at USC, I already had prototypes of the Rift that were very similar to the final design.

Virtual reality is inevitably going to become mainstream - it's only a question of how good it needs to be before the mainstream is willing to use it.

The whole thing with VR is that it doesn't matter, local versus networked gaming. The goal in virtual reality isn't to have people sit in the same room with headsets on.
