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.

Storage systems with calibration capabilities

A wearable electronic device can include displays and/or cameras that can be calibrated for accurate recording and visual output. Whereas some aspects of a wearable electronic device can be calibrated at the time of production, usage and wear of the wearable electronic device can result in certain components becoming misaligned. A calibration device can provide an output that serves as a reference for each of a pair of displays of the wearable electronic device. Each of the displays can be independently adjusted so their corresponding outputs are properly aligned with the view of the external environment.

Optical calibration

A securement arm for an optical device includes a first portion having a first electronic component, the first portion connected to a viewing frame of the optical device. The securement arm also includes a second portion having a second electronic component coupled to the first portion by a spring element. The spring element can include a plastic deformation element and an elastic element. The securement arm also includes an electrical connector extending through the spring element and electrically connecting the first electronic component and the second electronic component.

Securement arm for electronic device

A head-mounted device may have head-mounted support structures configured to be worn on a head of a user. The head-mounted device may have stereo optical components such as left and right cameras or left and right display systems. The optical components may have respective left and right pointing vectors. Deformation of the support structures may cause the camera pointing vectors and/or the display system pointing vectors to become misaligned. Sensor circuitry such as strain gauge circuitry may measure pointing vector misalignment. Control circuitry may control the cameras and/or the display systems to compensate for measured changes in pointing vector misalignment.
