About HTC Vive Headset
HTC Vive is a virtual reality head-mounted display made by a partnership between HTC and Valve Corporation. The headset was announced at Mobile World Congress in Barcelona and will be released to the market on Holiday 2015.
HTC Vive headset is powered by SteamVR which built from the ground up to provide consumers with a full virtual reality experience. This includes, among others, proprietary SteamVR wireless controllers which were designed to help users interact with the objects in the virtual world. Developers can take advantage of the SteamVR API for free and also OpenVR SDK that comes without the Steam functionality to develop games for supported platforms. We can assume that we'll see more Steam VR based headsets from other manufacturers coming in the near future, not just from HTC.

On the hardware side, the HTC Re Vive (aka HTC Vive) features a 1200x1080 per eye resolution running at 90Hz refresh rate (90fps) and provides 110-degree field of view (FOV). This provides gamers with a crisp and clear view of the image stream without any jitter. This is critical to allow gamers to play for a long time with as little stress on the eyes as possible.
Furthermore, the HTC Vive VR headset utilizes 70 different sensors, including a gyrosensor, accelerometer, laser position sensor, and Steam VR dual pulsed laser base stations (aka "Lighthouse"). Those are used for measuring your head rotation and your physical movement and apply that data to the virtual world you are in. The base station sensors allow the HTC Vive headset to track your location up to 15 feet.This opens a whole new world of possibilities for designing unique and innovative gameplay interactions. This is a unique feature for the HTC Vive, and I'm sure many game developers will jump over to take advantage of it.
The success of the HTC Vive will be tight to its adoption among game developers, but with a complete integrated support for SteamVR in Unreal Engine 4, we can be sure that many game developers will adapt this technology for their upcoming titles.
HTC Vive was released with a two wireless controllers and two base stations, that enable players to experience a 360° room-scale experience. This is why many of its titles are aimed for room-scale experience, compared to its competitor, Oculus Rift, which was launched without its "Oculus Touch" controllers, which are planned to be released in the 2nd half of 2016. Gamers and reviewers who tried both have reported that HTC Vive is the upper hand, but things might change once Oculus has its Touch tracked-motion controllers released.HTC Vive is certainly the headset of choice for many hardcore gamers who want to get the best possible VR experience at launch.
