Tracking section of the XTAL runtime settings contains all settings for currently selected tracking system (for example tracker selector and motion compensation for Lighthouse tracking, axes/body selector and IP/port options for ART tracking, tracker offsets for Polhemus tracking, etc.).

  • Calibrate IMU
    • If you are using the ‘Internal’ tracking option, we recommend recalibrating the IMU each time after starting a VR application, to limit the drift of the accelerometers/gyroscope
    • Make sure that the headset is stable (not moving) before resetting the IMU sensor (otherwise the accelerometers will not be calibrated properly, and the tracking can start drifting by itself)
  • Calibrate position
    • Sets the tracking origin for 6DoF tracking to the current location of the headset
    • Make sure that the headset is placed on the ground in the middle of the tracked space, before using this option
    • If you want to use standing/seating tracking space only, you can also calibrate the position when the headset is on users’ head (for this calibration mode make sure that the ‘Calibrate relative to ground’ checkbox is unchecked)
  • Reset calibration
    • Resets tracking calibration to default values (deletes the tracking origin set previously with ‘Calibrate position’ option)
  • Origin offset
    • can be used to manually move the tracking origin to fine tune the calibrated position
  • Merge with internal sensor
    • this option is available for most tracking systems, and it utilizes the internal IMU sensor to achieve better results with 6 DoF tracking systems
    • we recommend leaving this option checked for most use-cases
  • Additional options for specific tracking systems
    • see Lighthouse/SteamVR page for details about Lighthouse tracking
    • see ART page for details about ART tracking
    • see Optitrack page for details about Optitrack tracking
