Abstract: A display system may include a wearable display for rendering a three-dimensional virtual image content which appears to be located in an environment of a user of the display. The relative positions of the display and one or more eyes of the user may not be in desired positions to receive, or register, image information outputted by the display. For example, the display-to-eye alignment may vary for different users and/or may change over time (e.g., as a user moves or as the display becomes displaced). The wearable device may determine a relative position and/or alignment between the display and the user's eyes by determining whether features of the eye are at certain vertical positions relative to the display. Based on the relative positions, the wearable device may determine if it is properly fitted to the user, and position render camera(s) accordingly to present virtual image content.

Abstract: A wearable device may include a head-mounted display (HMD) for rendering a three-dimensional (3D) virtual object which appears to be located in an ambient environment of a user of the display. The relative positions of the HMD and one or more eyes of the user may not be in desired positions to receive, or register, image information outputted by the HMD. For example, the HMD-to-eye alignment may vary for different users and may change over time (e.g., as a given user moves around or as the HMD slips or otherwise becomes displaced). The wearable device may determine a relative position or alignment between the HMD and the user's eyes by determining whether features of the eye are at certain vertical positions relative to the HMD. Based on the relative positions, the wearable device may determine if it is properly fitted to the user, provide feedback on the quality of the fit to the user, and take actions to reduce or minimize effects of any misalignment.
