Oculus talked about a lot of potential uses for virtual reality at its event last week where it unveiled the, Crescent Bay model of the Oculus Rift headset, but Chief Executive Officer Brendan Iribe said that the heart of Oculus will always be in gaming.

"For a very long time the heart and soul of what drives virtual reality is going to be a video game 3D engine," Iribe told Games Industry International. "This is not a film, this is a 3D game engine inside. So even when it's a medical simulation experience or it's architecture or whatever it is, it is a 3D game engine running inside. That's awesome, that is rooted in the game market."

During Oculus' event last week, Chief Technical Officer John Carmack, Founder Palmer Luckey, and Oculus' Chief Scientist Michael Abrash discussed many of the challenges and possibilities with virtual reality.

Carmack especially emphasized the importance of social interaction. "Getting that multiuser experience is our most important user-visible feature," he said. "It's surprising that it hasn't been done so far. As the basics mature, I expect more of that to be going on...When you see grandparents using iPads to look at pictures of their kids. It's going to be the same with VR. Everyone in the world will find something to do with it."

Iribe said that the leap between Oculus Rift Developer Kit 2 and Crescent Bay is as significant as the leap between Oculus Rift Developer Kit 1 and 2. It's lighter, with improved ergonomics, 360 motion tracking, and integrated audio, a new focus for Oculus. The company didn't say when it will have a consumer version of the Oculus Rift, but that the Crescent Bay model comes close.
