HTC unveiled  at Mobile World Congress 2015 in Barcelona its virtual reality helmet, the HTC Vive. The helmet was developed in partnership with Valve Software.

The HTC Vive has a screen of 1200 x 1080 pixels for each eye, which will allow it to completely fill in the user's field of view with a refresh rate of 90 frames per second. It includes a gyroscope, an accelerometer, and a position sensor capable of detecting the rotation of the head of the user with an accuracy of one tenth of a degree.

But his main innovation is the ability to associate the headphones to SteamVR two stations that allow the user tracker's position as it moves into a space of up to 4.5 x 4.5 meters from surface. This technology will be associated with two controllers, one in each hand, which follow precisely the user's movements (like a Wii Plus controller) for it to interact with the virtual world.
