Abstract
A method of automatic image alignment with head mounted display (HMD) optics includes generating a pixel pattern of display light on an electronic display of the HMD. A light sensor of the HMD then generates light measurements in response to the pixel pattern, where the light measurements are representative of a lateral position of an optical element of the HMD. The method also includes adjusting a rendering center of the electronic display for presentation of one or more images with respect to the optical element based on the light measurements.
