CV tag based systems are ideal for differentiating among groups of objects and are vital when contents differ but shapes are the same, such as glue versus eye drops.
“CV tag based systems are ideal for tasks that require differentiating among groups of objects. They are vital for PVI when the contents of the items are different, such as a tube of glue versus a tube of eye drops, as they have the same shape and it may be dangerous if they choose the wrong one [92].”

“Fewer participants said they would mainly rely on AI when [71, 130, 151], half of the participants said they leaned towards just relying on human-sighted assistance when searching for a specific product at a physical store (54.7%, 𝑛 = 47) or browsing in a physical store (48.8%, 𝑛 = 42).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
