A self-imaging device, which may lack an active visual display, has an alignment indicator that a person can view to determine when he or she is positioned properly in front of the self-imaging device. The indicator comprises a lenticular lens panel having lenses that are positioned over respectively corresponding graphical patterns. Depending on the configuration of the graphical patterns, the lens panel projects different composite images in different directions. When the person is properly aligned, the person will observe a composite image that indicates alignment. When the person is not properly aligned, the person will observe a composite image that indicates non-alignment. The graphical patterns are illuminated by a light guide, which is a panel that distributes light across the graphical patterns.

A multiple-image display body includes a spacer layer, a line tone barrier layer stacked on the first surface of the spacer layer, and a multiple-image formation layer stacked on the second surface of the spacer layer. The line tone barrier layer includes first regions, which transmit electromagnetic waves, and second regions, which absorb electromagnetic waves. The multiple-image formation layer includes images that are visible when observed from specific angles over the first regions of the line tone barrier. The image is formed by a contrast resulting from an area ratio of the third region, which scatters electromagnetic waves, and the fourth region, which absorbs electromagnetic waves.

A number of illustrative variations may include a method of relative localization via the use of simultaneous location and mapping gear sets.

A transparent resin is injection molded to create a marker (10) as an integrally molded article (lenticular lens portion (11)) including convex surfaces (112) and recesses (113) formed on the rear side of the convex surfaces. The recesses (113) are filled with coating films (115) formed by applying and curing a fluid coating material. Each recess (113) is arranged corresponding to a convex surface (112) so that the coating films (115) can be observed as optically distinguishable from the side of the convex surfaces (112).
