Abstract: A head mounted device includes a light sensor configured to generate light data in response to measuring scene light in an external environment of the head mounted device, a display configured to present a virtual image to an eyebox area of the head mounted device, a near-eye dimming element configured to modulate a transmission of the scene light to the eyebox area in response to a transmission command, and processing logic configured to adjust the transmission command of the dimming element in response to a brightness level of the virtual image and the light data generated by the light sensor.

Abstract: A method for realigning components of image-projection systems for a head-wearable devices is described herein. The method includes, while an image is being presented to the user's first eye using a first image-projection system of a head-wearable device and the image is being presented to a user's second eye using a second image-projection system of the head-wearable device, selecting one or both of (i) a selected point in time at which to present a realignment pattern via the head-wearable device and (ii) a selected location within the image at which the realignment pattern should be presented. The method further includes, presenting, via the head-wearable device, the realignment pattern at one or both of the selected point in time and the selected location. The method further includes, modifying presentation characteristics for the first image-projection system or the second image-projection system based on the presenting of the realignment pattern.
