1. A head-mounted display system comprising:
a head-mounted display configured to project light into the eyes of the user to display virtual image content;
an eye-tracking camera system configured to image a left eye of the user and a right eye of the user;
processing electronics comprising one or more processors; and
non-transitory computer-readable media storing instructions which, when executed by the processing electronics, cause the processing electronics to perform operations comprising:
calculating a left eye tracking confidence score indicative of a confidence level in a position of the left eye and a right eye tracking confidence score indicative of a confidence level in a position of the right eye;
determining whether the head-mounted display is properly registered to the eyes of the user; and
providing feedback to the user if the head-mounted display is not properly adjusted to fit the user,
wherein the left eye tracking confidence score is based on one or more of detecting a number of glints in the left eye, detecting that the user is blinking, detecting that the left eye is moving, and detecting that the pupil of the left eye is on a boundary of an eye tracking image, and
wherein the right eye tracking confidence score is based on one or more of detecting a number of glints in the right eye, detecting that the user is blinking, detecting that the right eye is moving, and detecting that the pupil of the right eye is on a boundary of an eye tracking image.
