Eyes page contains all IPD and eye tracking related options.

  • Pupillary Distance
    • Auto IPD
      • You can start the Auto IPD function to measure the pupillary distance, and you can also limit it to use left or right eye camera only.
    • Left Eye / Right Eye
      • Separate slider for left and right eye can be used to manually change IPD values.
      • The distance for each eye can be set in range 30 – 37 mm per eye (60 – 74 mm total IPD) for XTAL 3 headsets or 28 – 37 mm (56 – 74 mm total IPD) for XTAL 8K/5K headsets.
  • Eye Tracking
    • Calibration
      • You can start the eye tracking calibration, and you can select which calibration mode will be used.
      • Simple mode calibration uses the same one-point pattern as the Auto IPD function.
      • Advanced calibration uses a seven-point calibration pattern for better eye tracking precision.
    • Autostart
      • If Autostart is enabled, eye tracking will be automatically started after successful calibration.
    • Enable Eye Tracking
      • Allows enabling or disabling the eye tracking.
      • Eye tracking can be either used for foveated rendering (if VR application supports it), or the eye tracking results can be visualized in real-time (see Heatmap options below).
  • Heatmap
    • This section is only available when eye tracking is calibrated and running.
    • Type
      • You can select a type of eye tracking visualization.
      • Heatmap type will show a persistent heatmap which adds intensity to areas over time as user is looking at them.
      • Trail type will show a temporary visualization which disappears after few seconds, so it will always show only the latest areas which user was looking at.
    • Show Heatmap
      • Shows or hides the eye tracking visualization inside the VR View window.
    • Headset Overlay
      • Shows or hides the eye tracking visualization inside the headset.
      • Be aware that this will influence the eye tracking results slightly, as user will most likely sometimes focus on the eye tracking visualization itself.
    • Clear Heatmap
      • Can be used to clear the currently displayed eye tracking visualization.
    • Resolution
      • Can be used to change the resolution of displayed eye tracking visualization.
    • Opacity
      • Can be used to change the opacity of displayed eye tracking visualization.
