Integrated eye tracking is available for using with all Varjo headsets, and allows to follow the headset user’s eye movements with a sub-degree accuracy.
The eye tracking has been designed to work with most single-vision eyeglasses. However, the technology is not guaranteed to work with all medical devices or eye conditions.
Calibrating eye tracking
Eye tracking calibration is done by following a moving dot with your eyes. This sequence typically takes less than 30 seconds.
For eye tracking to work accurately, position the headset correctly so that the cameras can see your eye movements. Make sure that the headset stays firmly in place while you are wearing it and that the image looks sharp. The headset may show you additional instructions on how to correctly position the headset before calibration starts.
Your application can be programmed to start the calibration automatically. You can also start the calibration manually. See instructions below depending on your headset model.
XR-4 Series, XR-3, VR-3, and Varjo Aero
Depending on your use case, often the single-dot calibration for foveated rendering can be sufficient for good quality eye tracking. For more accurate eye tracking, navigate to the Tools menu in Varjo Base, select Analytics window and choose Eye tracking > Calibrate.
If you have turned on Remember my calibration in Varjo Base, you don’t need to calibrate between sessions.
