VR Object Setup

Dynamic cameras are only supported on the original configuration Oculus Rift with external sensors. If you're using a Rift S, you can skip to the Camera Calibration step.

Mixed reality capture uses a VR Object to track the location of a dynamic camera. This page describes the process of setting up a VR Object. If you’re planning to use a static camera that does not move around the scene, you may skip this step. A VR Object is a Touch controller with updated firmware. You may use one of the existing Touch controllers paired to your HMD as a VR Object. However, you’ll need to re-pair the controller to your HMD if you want to use it as a regular Touch controller again. We recommend using a third Touch controller that can be a permanent VR Object.

Note: Early, pre-production, Touch controllers (version C06x and earlier) will not work as VR Objects. Identify these controllers by checking the serial number found inside the battery housing. These Touch controllers will have the following serial number: “WMTCL1xxxxxxx” or “WMTCR1xxxxxxx” for left and right Touch, respectively. To create your VR Object you’ll need to update the device firmware.

  1. Launch the Oculus desktop application, open the settings menu, and select the Devices tab. Then, from the dropdown, select Pair VR Object (Advanced).
  1. On the first screen, identify which controller, left or right, you are using as the VR Object.
  2. Follow the on-screen prompt to pair the controller as a VR Object. This process will update the device firmware.

The VR Object will remain active for 24 hours while the proximity sensor on the HMD is covered. Otherwise, the VR Object will go into standby mode after 30 seconds. Any button press or movement will return the VR Object to active mode. To re-pair your Touch controller to the original HMD (if you did not use a 3rd Touch).

  1. In the same dropdown that you selected the option to pair your VR Object, select Pair Touch.
  2. Follow the on-screen prompts to pair the controllers.

Mounting the VR Object

Once you’ve created your VR Object, you’ll need to attach the Touch to your external camera. There are a number of ways to do this, we recommend using the mount provided in the Mixed Reality Capture Mount Accessory Guidelines. The download contains two CAD files that can be used to 3D print a camera mount that holds a Touch controller, one for each a right and left Touch controller. The mount is designed to be used with webcams and small DSLRs. Larger cameras may not fit on the mount.

First, print the controller mount on a 3D printer. For best results, print the mount on the highest quality setting using Polyjet or SLS print methods. We have found that ABS, or equivalent, print materials work well with this mount design.

Mount Configuration and Assembly

Once you’ve printed the mount, you can attach the camera, VR Object, and tripod (or a steady camera mount).

  1. Use a 3/4 inch bolt or cap screw to attach the mount to the tripod. A nut or wing nut may be used to secure the mount for a stable connection.
  2. Use a 1/2 inch bolt or cap screw with a washer to attach the camera to the mount. If a washer is not used, you may need to use a shorter bolt depending on the camera you’re using.
  3. (Optional) You may wish to use small zip ties to secure the Vr Object to the mount. A change in relationship between the VR Object and camera may require you to reclibrate the camera.
