LOS ANGELES -- Oculus has unveiled a new prototype of its virtual reality headset. However, the VR company still isn't ready to release a consumer edition.

The new headset intended for creators of VR experiences is nicknamed Crescent Bay and features a higher resolution and refresh rate, integrated headphones and 360-degree head tracking.

"That was not easy," Oculus CEO Brendan Iribe told the audience Saturday at the company's first-ever developers conference. "It's still not perfect. None of this is perfect yet, but it's much, much better."

Oculus' headset covers a user's eyes and can create immersive worlds that react to head movement.

The original prototype of the Oculus Rift headset was unveiled in 2012 and has received considerable attention from film and video game makers. Iribe said 100,000 development kits have been shipped to 130 countries.

The Irvine, California-based Oculus VR Inc. was acquired by Facebook earlier this year for $2 billion. Iribe said Oculus' staff has doubled in the six months since the acquisition.

"We're really spiriting toward the consumer version," he said.

Over the past two years, Oculus' technology has been demonstrated at events like San Diego Comic-Con and the Electronic Entertainment Expo with interactive experiences that recreate scenes from the "X-Men" and "Pacific Rim" films and thrusts users into an intergalactic dogfight in the game "EVE: Valkyrie."
