HTC and Valve announced the HTC Vive today, a headset similar to the Oculus Rift. The differences are in the head tracking, a slight increase to resolution compared to the Oculus Rift DK2, and a custom game controller.
Similar to the VR room demo Valve had at Steam Dev Days, the HTC Vive will have tracking for your location relative to the physical room you’re in. The VR room demo used something similar to QR codes printed out on the walls to do this, the HTC Vive uses SteamVR base stations. The SteamVR demo at dev days was super impressive when I got to try it, and kind of ruined the experience of trying the Oculus Rift. Nothing on the Rift could match the feeling of scale I got from the SteamVR demo. It must be even more impressive on this new hardware.
Developer kit ships this spring, user version late in the year. Between this, Oculus, Nvidia announcing something soon, and Sony’s headset, some standard API will need to emerge to support all of them and I bet that’s what Valve will focus on fixing.
