摘要

The arrangement has at least one observable part (BT) whose visual appearance when the user is observing the part depends on the viewing angle to the part being observed so that at least one symbol is visible to the user or not visible. A lens (KL) of a camera module is arranged on the same side of the equipment as the arrangement and the appearance depends on the viewing angle so the visibility of at least one symbol depends on the image acquired by the lens. An independent claim is also included for the following: (a) a method of operating a device with at least one part with a symbol that appears to the user or not depending viewing angle.
