Tracking

Software > Somnium VR1 Tool > Somnium VR1 Tool UI > Settings > Tracking

Tracking page contains all tracking related options.

  • Origin
    • Can be used to manually move the tracking origin (X, Y, Z, Yaw) to fine tune the calibrated position.
    • Clicking the Reset button will reset all Origin sliders to default values (0).
  • Calibrate Position
    • Clicking the Calibrate button will save the current headset position as origin (0,0,0) for your VR space.
      • When using a room scale application with 0 floor level, we recommend placing the headset on the ground and then pressing this button.
    • Clicking the Reset button will remove previously saved calibration, so raw data from the tracking system will be used.
    • The position calibration will not work if you are using the SteamVR Driver, as in that case the VR space is configured through SteamVR itself.
  • Calibrate Relative to Ground
    • If this option is enabled it will add extra vertical offset to the current headset position to match the bottom of the headset.
    • We recommend using this option when calibrating position of the ground, so the bottom side of the headset will correspond to the floor level.
  • Lighthouse
    • Internal Sensor Merge
      • When this option is enabled, SteamVR/Lighthouse tracking will be merged with the internal IMU sensor data.
      • This can lead to faster tracking response during fast rotational movement, but as SteamVR tracking already contains its’ own IMU sensor we recommend leaving this option unchecked for most use-cases.
    • Motion Cancellation
      • If you’ll be using Somnium VR1 headset on a motion platform, you can utilize secondary SteamVR/Lighthouse tracker for direct platform movement cancellation/compensation.
      • When Motion Cancellation is enabled you can select tracker ID from a list of all available SteamVR trackers. You can also use the Refresh IDs button to reload the list of SteamVR trackers.
    • Legacy Input
      • When this option is enabled, an older legacy version of SteamVR input API will be used for communication with SteamVR controllers.
      • You should only use this option with applications which don’t support new SteamVR input API.
