At Oculus, we're now looking at eye specialists, people who really understand how the human eye works, and how that affects human emotion.

When I saw how real virtual reality can be, and that we can replace human vision with virtual vision, this can be the ultimate platform.

We've spent a lot of time on ergonomics. That was something we found to be really important as we iterated on the headset, from developer kits to Crescent Bay to the Rift.

As people are showing the Rift to friends, word will spread that VR can be that good. So I'm not so worried in terms of adoption of the Rift.

It just felt like the right thing to do to give back to a state school and public school. I'm a really big fan of public education.

There are millions of sci-fi enthusiasts in the world, not just gamers.
