Eyes

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.
  • Capture Heatmap
    • Enables or disables the heatmap functionality.
    • If this is enabled, heatmap data will be measured, but they will not be visualized automatically. To show the heatmap visualization you’ll also need to enable “Show Overlay” option below.
  • Show Overlay
    • Shows or hides the eye tracking visualization inside the headset and in the VR View window.
    • 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.
