Assessment Descriptor

Brief visual attributes of objects — such as color, size, dimensions, and distance from the user — provided alongside obfuscated or spotlighted content to help users verify whether privacy techniques are working correctly. Research with blind participants has shown that common assessment descriptors reflecting sighted assumptions (color, measurements, location) are often inadequate, and that descriptors naming objects directly, including text content, and describing the surrounding environment are more useful for non-visual verification.
