Abstract
A system may include a head-mounted device and a storage case for storing and calibrating the head-mounted device. The storage case may include a recess that receives the head-mounted device. The case may include optically detectable features for calibrating cameras in the head-mounted device. For example, the case may include optical charts, physical fiducials, and/or reflective calibration spheres for calibrating inward-facing cameras on the head-mounted device such as gaze tracking image sensors. For calibrating outward-facing cameras on the head-mounted device that have larger focal distances, the case may include a light source and a diffractive optical element to create a light pattern that virtually originates from infinity. The case may include cameras for capturing images of displayed images on the head-mounted device to determine if a waveguide and display in the head-mounted device are misaligned.
