An article on PC Pro has details on the HTC RE Vive VR headset, saying this is the SteamVR hardware first mentioned last week (thanks QuaziModem), and there's an article on BBC News with further technical details. This video introduces the headset to some degree, concluding saying these will be in stores for the holidays and a developer edition will be available in the spring. The video carries the Valve logo along with HTC's, and the description says: "HTC’s Vive headset, powered by SteamVR, pulls those virtual worlds off your computer screen and into your home. You’ll experience sights and sounds vivid and lifelike enough to transport you to another place, another time—whole new realities with limitless possibilities." Here's more from PC Pro:

While the likes of Oculus Rift or Project Morpheus work by tracking a user's head movements while requiring an input device for movement, Vive doesn't.

Using technology prototyped in the Crystal Cove Oculus headset that Valve helped develop, the HTC Vive seems to be able to track the whole environment. This means that it can track where someone is in a room and when they change location, they move in the game world too.

According to HTC's Jeff Gattis, the HTC Vive will offer a fast 90Hz refresh rate with 360-degree views - although we're a little sceptical as to how that's possible.

According to a press release from HTC, the Vive promises a "full room-scale" experience for virtual reality, "letting you get up, walk around and explore your virtual space, inspect objects from every angle and truly interact with your surroundings".
