Newer versions of the Oculus Rift eliminate its motion sickness problems, says Oculus CEO Brendan Iribe.

Speaking today at the Gaming Insiders conference in San Francisco (as reported by Polygon), Iribe admitted that his company’s flagship device used to make him ill.

"I've gotten sick every time I've tried it. Every time until recently," he said.

"In the last few weeks, I stayed in it for 45 minute sessions and I did not get sick with the new prototype. We are at the edge of bringing you no motion sickness content."

Iribe said much like other substantial technological leaps forward, the Rift would not be perfect from the outset.

He cited a need for advancements in the headset’s resolution, latency, persistence and judder, and field of view, among others.

Similarly, those creating content for the Rift would need to conquer VR challenges such the user interface, player cues, storytelling, 3D audio, and user uptake.

Iribe predicted that along with immersive experiences, the Rift could be used as an "IMAX viewer" for 2D games.

"This is day zero. We are at the very beginning of VR," he said.

"This is the future of gaming as we see it. Hardware drives content innovation. A new platform offers new abilities that developers use to create content which in turn sells hardware."

Oculus Rift kits are currently available for developers. An improved Rift 2.0 is is in development for consumers.
