Install the Kinect runtime (v1.8 for Xbox 360 version, v2.0 for Xbox One). Copy the dll to your osvr-plugins-0 folder (the binary should match your OSVR version - the OSVR all-in-one installer is 32-bit).

When you start osvr_server a config window should pop up showing how many bodies are visible to the Kinect sensor, allowing you to choose which body is tracked. You can also recenter the coordinate system and activate seated mode if you're using Kinect 1.

When using a HMD the orientation and position data will likely be misaligned, eg, you are facing forward and leaning forward, but your tracked position instead moves to the side. To correct this, align the orientation tracker with the position tracker's axes and run osvr_reset_yaw on the orientation tracker.

For example, with the OSVR HDK and a Kinect, you would place the HDK in front of the Kinect, pointing towards it, then run

osvr_reset_yaw.exe --path "/com_osvr_Multiserver/OSVRHackerDevKitPrediction0/semantic/hmd"
