Hello.

Is there a similar document but for controller? I've spend whole yesterday trying to find any reference material. I want to know where exactly is center of coordinate reference frame of a controller.

There isn't a full Are you looking for the coordinate system as reported by OpenVR or via a specific game engine (Unity or UE4). The Vive tracker has radial symmetry whereas since the controller is more assymetric, the game engines often add abstraction layers because they're working with a full 3D model and there are "interaction points"

I am getting coordinates and rotation matrix via OpenVR. So, for integration in mind I want to know where is coordinate origin of the control. Around which physical space I can turn my control around without changing it's position and only change yaw,pitch,roll angles? Where is this point in relation to physical device?

Here's Unity's docs for what this is worth:

https://docs.unity3d.com/550/Documentation/Manual/OpenVRControllers.html

 

The center is around the menu button - you can easily see where it is by casting a ray from the controller's origin - see example code from VIU Unity plugin to cast rays (VivePointers) from the Vive controllers.

Alright! Thank you for that information ! It's better then nothing.

Thought for my application I would relly like to have something much more specific. 

I want to use Vive Controller as a position/orientation ground truth recorder/detector for some other device that I Want to tell me same information. For that I am planning to design and 3D print a mount that would hold my device and attach to the controller. To math to work I would like to have precise relative position/orientation between my device and center of rotation of the vive controller.

I cannot create a post to be able to get help from a developer but I am having troubles with my vive trackers and none of the support lines or online services can help my issue, can you link me where i can post my issue and recieve help?
