A new ovrProperty, VRAPI_ACTIVE_INPUT_DEVICE_ID, was added to query the device ID of the primary or most active input device.
A new ovrTrackingSpace, VRAPI_TRACKING_SPACE_LOCAL_TILTED, was added for applications that support “bed mode.”” This space defines the tilted orientation a user would like their content displayed in.
A new ovrTrackingSpace, VRAPI_TRACKING_SPACE_STAGE, was added. This space has its origin on the floor at the center of the play area with its forward direction pointed towards one of the edges of the bounding box.
A new ovrTrackingSpace, VRAPI_TRACKING_SPACE_LOCAL_FIXED_YAW, was added. In this space, the origin is the same as local space, however the yaw remains fixed to the physical environment. This space may be useful for swivel-chair roaming games.
