A state visualizer according to one aspect of the present disclosure includes an optical member including a fixed part that has a fixed relative positional relationship with an object to be measured and a movable part that is movably supported by the fixed part and keeps a constant angle with respect to a gravity direction, the optical member retroreflecting a light or an electromagnetic wave in a case where the fixed part and the movable part are in a predetermined positional relationship. The optical member changes an intensity of the light or the electromagnetic wave reflected in a retroreflection direction in accordance with a change of a relative positional relationship between the fixed part and the movable part.

In one exemplary embodiment, a system, method and apparatus for increasing the visibility of a garment or article of clothing may be described. This can include an element of a garment which may be functionally or structurally integrated into the garment, such as a heat transfer. The heat transfer can utilize any number of visibility-enhancing elements to increase the visibility of a wearer of a garment having the heat transfer, for example through any combination of reflective elements, retro-reflective elements, and elements formed in various colors.

An apparatus comprising a retro-reflective marker and a device configured to receive the retro-reflective marker in a socket located on the top surface of the device. The retro-reflective marker comprises a retro-reflective layer having a first retro-reflectance capability. The retro-reflective layer comprises a textured surface, a portion of the textured surface having a surface topology such that surface normal vectors positioned across the portion extend from the portion of the textured surface in different directions, and a plurality of retro-reflective micro elements distributed across the textured surface. The retro-reflective marker further comprises a border defining a retro-reflective area of the retro-reflective layer, where a portion of the border provides a second retro-reflectance capability lower than the first retro-reflectance capability.
