    Abstract: A stabilization actuation assembly includes a lens barrel, a magnetic assembly, one or more stabilizing coils, an outer shell, and a piece of ferromagnetic material. The lens barrel is configured to carry a lens that is positioned along an optical axis. The magnetic assembly includes a plurality of magnets that produce a magnetic field. The one or more stabilizing coils are coupled to a printed circuit board below the plurality of magnets. The outer shell includes an aperture through which the lens barrel can actuate. The piece of ferromagnetic material is coupled to a surface of the outer shell and is positioned to augment the magnetic field. A current supplied to the one or more stabilizing coils interacts with the augmented magnetic field to cause the magnetic assembly together with the lens barrel to translate in a direction perpendicular to the optical axis.

    Abstract: A display assembly generates environmentally matched virtual content for an electronic display. The display assembly includes a display controller and a display. The display controller is configured to estimate environmental matching information for a target area within a local area based in part on light information received from a light sensor. The target area is a region for placement of a virtual object. The light information describes light values. The display controller generates display instructions for the target area based in part on a human vision model, the estimated environmental matching information, and rendering information associated with the virtual object. The display is configured to present the virtual object as part of artificial reality content in accordance with the display instructions. The color and brightness of the virtual object is environmentally matched to the portion of the local area surrounding the target area.
