1. A method comprising:
at a device including a depth sensor including a plurality of depth sensor elements, a display having a plurality of display locations, one or more processors, and non-transitory memory:
obtaining content to be displayed on the display in association with a physical environment;
selecting a subset of the plurality of depth sensor elements corresponding to a subset of the plurality of display locations;
activating the subset of the plurality of depth sensor elements corresponding to the subset of the plurality of display locations without activating others of the plurality of depth sensor elements to obtain a depth map of the physical environment; and
displaying, on the display, at least a portion of the content based on the depth map of the physical environment.
