Abstract: A method for passively calibrating and verifying eye tracking in a surgical robotic system. The gaze of a user facing a user display of a user console of a surgical robotic system is tracked while the user is using a user interface device (UID). When a user interaction to the UID is detected, an expected gaze position on the display of the user console is determined without instructing the user to look at the expected gaze position. The latter becomes a reference gaze point of the user at the time of detected user action. The measured gaze point of the user is compared with an acceptable threshold of the reference gaze point, and in response to a determination of a mismatch, calibration parameters used by the tracking are adjusted according to the reference gaze point. Other aspects are also described and claimed.
