Abstract: A method for calibrating eye tracking data for a head wearable optical device includes receiving eye tracking data from an imaging device oriented towards a combiner. The method includes determining a gaze direction of an eye of a user based on the eye tracking data. The method includes receiving calibration data from the imaging device that includes an indication of positions of one or more calibration indicators. The method includes determining the gaze direction based at least in part on the calibration data received from the imaging device (or factors adjusted by the calibration data).

Abstract: A disclosed computer-implemented method may include directing a display device included in a head-mounted display worn by a user to illuminate, via a projection of a line at an illumination time, a portion of a cornea of the user. The method may further include detecting, via an image sensor at a detection time, a portion of the projection of the line reflected by the portion of the cornea of the user and identifying a distortion of the projection of the line reflected by the portion of the cornea of the user. The method may also include determining a shape of the cornea of the user based on the illumination time, the detection time, and the distortion of the projection of the line reflected by the portion of the cornea. Various other methods, systems, apparatuses, and computer-readable media are also disclosed.

Abstract: The disclosed eye-tracking systems may include a visible light display having visible light pixels, at least one infrared pixel positioned within bounds of the visible light display, and an infrared sensor positioned and configured to detect infrared light originating from the at least one infrared pixel and reflected from an eye of the user. Related head-mounted display systems and methods for eye tracking are also disclosed.

Abstract: Various aspects of the subject technology relate to prediction of eye movements of a user of a head-mountable display device. Predictive foveated display systems and methods, using the predicted eye movements are also disclosed. Predictive variable focus display systems and methods using the predicted eye movements are also disclosed. Predicting eye movements may include predicting a future gaze location and/or predicting a future vergence plane for the user's eyes, based on the current motion of one or both of the user's eyes. The predicted gaze location may be used to pre-render a foveated display image frame with a high-resolution region at the predicted gaze location. The predicted vergence plane may be used to modify an image plane of a display assembly to mitigate or avoid a vergence/accommodation conflict for the user.

Abstract: An optical assembly includes an optically transparent substrate and a first lens removably coupled with the optically transparent substrate by one or more adhesive layers. The one or more adhesive layers are positioned between the optically transparent substrate and the first lens. Also disclosed are an eye-tracker and a display device, each of which includes the optical assembly.
