Oculus is the team behind the highly-anticipated Oculus Rift virtual reality headset, which Facebook acquired for $2 billion earlier this year.
Experiencing virtual reality through the Rift can be difficult to describe, but it's vastly different than seeing a 3D movie.
"I'm a strong believer that five to ten years from now, gaming on a flat 3D monitor will feel like gaming on a 8-bit system," Oculus CEO Brendan Iribe told Business Insider. "You will truly feel present in these virtual places."
When you try on a Rift, you're suddenly immersed in a 3D virtual environment that fills your field of view, causing you to feel like you're physically present in a virtual world. You can even gaze around, looking behind yourself, or lean in close to examine an object.
