Display systems and methods for determining registration between display and eyes of user

A method for controlling a display system including a wearable display configured to project light into eyes of a user to display virtual image content while the display is being worn by the user, the method performed by processing electronics of the display system and comprising:

• based at least partly on one or more eye tracking images of the eyes that are captured by an eye-tracking camera system of the display system, the eyes including a left eye and a right eye, calculating a left eye tracking confidence score indicative of a confidence level in a position of the left eye relative to the display and a right eye tracking confidence score indicative of a confidence level in a position of the right eye relative to the display;
• based at least partly on the left eye tracking confidence score and the right eye tracking confidence score, determining at least one render camera position to position at least one render camera for rendering the virtual image content;
• and
• causing the display to render the virtual image content based on the at least one render camera position,
• 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.

At least one non-transitory computer-readable storage media storing instructions which, when executed by processing electronics, cause the processing electronics to perform operations for controlling a display system including a wearable display configured to project light into eyes of a user to display virtual image content while the display is being worn by the user, the operations comprising:

• based at least partly on one or more eye tracking images of the eyes that are captured by an eye-tracking camera system of the display system, the eyes including a left eye and a right eye, calculating a left eye tracking confidence score indicative of a confidence level in a position of the left eye relative to the display and a right eye tracking confidence score indicative of a confidence level in a position of the right eye relative to the display;
• based at least partly on the left eye tracking confidence score and the right eye tracking confidence score, determining at least one render camera position to position at least one render camera for rendering the virtual image content;
• and
• causing the display to render the virtual image content based on the at least one render camera position,
• 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.
