Seeing other people is incredibly engaging, and that's one of the drivers that made us partner with Facebook - social communication. Not social newsfeeds, but actual face-to-face, seeing multiple avatars in a play experience, that's going to be a very big part of the future in VR.

I like to think of it as this new field. Instead of computer science, it's going to be virtual science.

I think a lot of people have an idea of virtual reality from science fiction, books and movies that have been out over the last couple of decades.

We designed a number of features from the ground up, like custom display and optics technology with very high refresh rates and pixel density. We added integrated 3-D audio, a built-in microphone so you can speak to friends inside virtual worlds, and precise mechanical adjustment systems.

You put on this set of goggles, and within seconds, your brain is convinced you're now in a different, virtual environment. You're somewhere else, and that somewhere else may be a video game, it may be in a real-time movie, a museum exhibit, or a medical surgical training app.
