We already know virtual reality promises to be big, not just for gaming, but entertainment in general, and possibly some social media, too, but Facebook, Samsung, and Oculus aren’t the only players interested in VR.

This week at Mobile World Congress in Spain, HTC is talking about its partnership with another tour de force in gaming, coming together with Portal makers Valve, a company that has been eyeing the virtual reality space for some time and is looking to bring its know-how in entertainment with its own solution.

“It’s rare that a company has an opportunity to forever transform the ways in which people interact with the world and communicate with each other but that is exactly what we plan to do with Valve,” said Cher Wang, Chairwoman of HTC.

The product that will make this happen is the HTC Vive, a virtual reality headset that will use a combination of specialised controllers that will make VR less passive and more interactive, making it possible for you to get up out of your seat and get up close to a digital scene, interacting with virtual digital objects.

HTC’s Vive headset will rely on two 1200×1080 screens for each eye, resulting in what we can only assume is a screen similar to what the Samsung Galaxy Note 4 and Gear VR offer, with roughly 720p per eye in the not-quite-square-on-each-side configuration.

Valve’s “SteamVR” interface will likely run here, likely needing to talk to a computer given how Valve’s Steam currently relies on a PC with either Mac, Windows, or Linux.

A combination of sensors will be used to track information, with a gyro sensor, accelerometer, and a laser position sensor to track left, right, up, and down, while the aforementioned specialised controllers places around the room will tell you how close you are to other objects, essentially allowing you to walk around your digital virtualised room.
