Abstract: A system and method of detecting display fit measurements and/or ophthalmic measurements for a head mounted wearable computing device including a display device is provided. The system and method may include capturing image data including a face of a user to be fitted for the head mounted wearable computing device. A three-dimensional head pose and gaze measurements may be extracted and a three-dimensional model may be developed from the captured image data. The system may detect display fit measurements and/or ophthalmic fit measurements from the three-dimensional model, and may provide one or more head mounted wearable computing devices that meet the display fit and/or ophthalmic fit requirements.

Abstract: A system and method of calibrating a head-mounted display (HMD) by positioning an optical combiner of the HMD into a holder of a calibration station such that the optical combiner is in a primary optical path of light provided from a micro-display of the HMD and a camera of the calibration station, adjusting a tunable correction unit to correct defocus caused by a corrective prescription of the optical combiner, capturing images of a reference target by the camera as viewed through the tunable correction unit and optical combiner, and generating a distortion model from the captured images and calibrating the HMD in order to apply the distortion model to images projected by the HMD.
