The HTC Vive was developed by HTC in collaboration with Valve. HTC recommends a 2 x 1.5-meter space to VR. You get 360˚ motion tracking with Vive thanks to breakthrough base station technology that helps the headset and controllers track their exact location in space. The HTC Vive plugs into PCs and work with Valve’s mammoth gaming ecosystem.
Great is that with Vive you are not sitting in the chair and watching VR, you are inside of VR while experience still needs more polishing.
