  1. Thanks for your answers. You were right, the orientation depends on the assigned roles. I checked the orientations of different roles. All roles, except the "hold in hand" role have the same orientation. Furthermore, the "hold in hand" role seems to switch its orientation from time to time...
  2. Hello, I realized that the orientation of my HTC Vive Tracker coordinate system is not like the Specification sheet defines it. The red arrows define the orientation that I measured. On top of that, sometimes the orientation seems to switch. @Jad @chengnay
  3. Hello, Just saw your answers. Thank you very much, that helps me a lot! The PDF is exactly what I was looking for. Cheers
  4. Okay thank you for your effort. So I am waiting for your/R&D team official answer. A picture/sketch of the position and orientation of the coordinate system on the HMD would be great to avoid misunderstandings!
  5. Thank you for your quick response. I am developing with the HTC VIVE (basic edition). I have found a CAD model of the HMD (I don't think an official one), is the position of the coordinate system shown correctly here? The first picture is the view from the bottom, the second the side view. .Is the orientation of the coordinate system correct? I have also found pictures where the positive z-axis points to the back (to the user). I also develop with the Leap Motion. Is the information that the offset of the origin from the Leap Motion device to the HMD origin in z-direction is 9.5 cm correct?
  6. Hello, I hope that the right sub area. I am using the HTC Vive with the OpenVR SDK to get orientations and positions of devices. Could someone tell me where I can find the exact position and orientation of the coordinate system of the HMD? When I search I find different information. Is the Z axis positive or negative in the user's direction of view? Is the CS centered on the surface of the HMD or inside the device? How is the orientation of the world coordinate system? Thanks so much for your help! @Jad @Dario
