A computing system, comprising: a camera; a light-emitting device; an artificial intelligence system that comprises one or more machine-learned models; one or more processors; and one or more non-transitory computer-readable media that collectively store instructions that when executed by the one or more processors cause the computing system to: obtain a query from a user; obtain an image of a scene captured by the camera of a computing device, wherein the scene comprises a plurality of objects; generate, by the artificial intelligence system and based on the query and the image of the scene captured by the camera, an attention output that describes at least one region of the scene that includes a subject of a processing operation performed by the artificial intelligence system, wherein the subject comprises an object of the plurality of objects selected based on the query; in response to generating the attention output: adjust the direction of emission of the light emitting device relative to the computing device when the computing device is moved relative to the scene such that the light-emitting device emits light onto or adjacent the at least one region of the scene that includes the subject of the processing operation performed by the artificial intelligence system; and provide a plurality of focus indicators (420, 422) for display, wherein the plurality of focus indicators (420, 422) are located proximate outer bounds or edges of the subject to indicate the outer bounds or edges of the subject and wherein the plurality of focus indicators (420, 422) comprise a plurality of laser beams emitted by the light emitting device. a camera;
