1) Mixed reality involves filming a person interacting with a VR game without wearing a headset. This gives viewers a first-person perspective without having experienced VR before. 2) To capture mixed reality, a studio is set up with green screens, HTC Vive controllers, a high-end PC and camera. The OpenVR SDK allows for mixed reality but requires developer support. 3) Setting up the camera is difficult and requires fixing a Vive controller to the camera for tracking. The game footage must be synced to the camera frame rate to overlay correctly. Precise alignment of the virtual and real cameras is challenging.
