1. A system comprising: one or more processors; a camera; a projector; and one or more non-transitory computer-readable storage media storing computer-executable instructions that are executable by the one or more processors to cause the one or more processors to: cause the projector to project an image on a surface; capture image information of the image, the image information representative of one or more objects within the image; determine motion information associated with the image based at least in part on the image information; determine, based at least in part upon the motion information, a region in the image for monitoring; detect that a change in an image attribute associated with the region meets or exceeds a first threshold; and adjust a focus parameter of the projector and project the image on the surface using the focus parameter, the focus parameter including at least one of a position setting or a motor setting of the projector.
