Halo helps an adult make one object findable for a child with cerebral (cortical) visual impairment, CVI. In CVI the eyes can work, but the brain struggles to pick one object out of visual clutter. Teachers and parents adapt photos by hand: one familiar object, a dark background, a preferred colour, placed where the child sees best. Halo does that from a photo of the child's own object. Muse Spark names the objects in the photo, SAM 3.1 cuts out the chosen one, and Halo places it where the adult chooses, on black, ringed in the adult's colour. Muse Image then re-photographs the object as a clean shot, and Halo's own verifier measures that image (one object, near-black background, size, centring, colour distance and shape match against the original) before it is ever shown. A rejected image falls back to the exact cut-out. Results open as a printable picture book.
