HTC on Sunday announced a new phone, a wearable and, perhaps even more exciting, a new virtual reality headset. It’s called the HTC Vive Developer Edition right now, and it was built in a partnership with Valve.

The headset, which we hope to see during the show in person later this week, integrates with Valve’s Steam VR tracking and input technologies. Unlike the Gear VR, the Vive does not work with a user’s phone, but instead relies on the power of a full computer. That implementation is more along the lines of what Oculus is doing with its VR solution.

HTC promises that the Vive will offer “the most immersive experience of any VR package,” and that it will include full room scale 360-degree viewing and tracked controllers, which means you’ll be able to walk around virtual worlds. Graphics are displayed at 90 frames per second, the company explained.

Content partners for the Vive include Vertigo Games, Bossa, Barry — Fireproof, Dovetail Games, Wemo Labs, Steel Wool Games, Owlchemy, Google, HBO, Lionsgate and the National Palace Museum in Taiwan, which means the headset will offer both gaming and virtual video content.

The HTC Vive will hit the market in its developer form this spring and a full consumer release is promised by the end of this year. Pricing was not announced.
