Tactile Icon

A small raised or three-dimensional symbol placed on a tactile map or diagram that represents a real-world object, location, or concept through touch. Tactile icons can be abstract (geometric shapes requiring a legend) or representational (physically resembling the object they depict, such as a miniature toilet for restrooms). Research shows that representational 3D icons are often more intuitive and memorable than abstract symbols, as they can be recognised without prior training or reference to a key.
