Abstract
Head-mounted augmented, virtual, and extended reality devices (AR/VR/XR HMDs, also known as smartglasses) are subject to deformation when worn by users. Deformation is a change in the device state or shape such that the device is no longer well described by factory calibration parameters to the detriment of user experience. This disclosure describes online or in-field calibration techniques to re-calibrate a head-mounted AR/VR/XR device in response to deformation. The techniques include determining the as-worn deformation state via device sensors and/or user input and updating the device calibration to compensate for the deformation. Updating device calibration entails determining calibration parameters as a function of deformation, a procedure that can be carried out in a robotic calibration platform. The techniques are generally applicable to head-mounted devices (HMD) and particularly to smartglasses form-factor AR products, which tend to experience more deformation.
