Someday, you might be able to sit down to watch Netflix’s “House of Cards” with a virtual-reality helmet strapped to your head, to see around corners and experience the political machinations in a 3D environment.

Or maybe not.

Whether VR is the future of entertainment — or just a passing fad — Netflix is among those tinkering with the technology.

Last week, a team of the company’s engineers worked up a demo of “Oculix,” a 3D virtual room of the Netflix interface using ’s Oculus Rift VR headset. The app included gesture support, so that when the viewer turns his or her head, the view of the “room” shifted accordingly. Facebook, for one, has placed a $2 billion bet on VR with its acquisition of Oculus (before the startup had shipped a consumer version of its product).

The Oculix demo emerged from Netflix’s latest Hack Day, held Aug. 14-15 at its headquarters in Los Gatos, Calif. More than 150 Netflix engineers participated in the event and produced more than 50 ideas — some jokey, and others that may hold commercial promise.

“If something interesting and useful comes from Hack Day, that is great, but the real motivation is fun and collaboration,” the event’s organizers wrote in a post on Netflix’s tech blog, noting that the concepts may never progress into actual products or services.
