This minimalist pictogram system is based on a uniform grid and spanned curves that represent sections of a circle. The symbols are used in various contexts, such as for buildings, rooms, technical devices and guidance systems. Applications range from simple information stickers to complex room-control devices. Thanks to a uniform line thickness, the icons are well suited for both small- and large-format applications. A strong contrast of black and white ensures that the icons are easy to recognise and can also be used on monochrome displays.
