What are tactile maps?
Haptic maps, which are also reffered to as tactile maps, are map sheets designed to be read by touch. Their base map is a standard map source converted to a simplified black-and-white graphic following the principles of tactile perception.
The graphic is optimised for technologies that use so-called microcapsule paper or “swell paper”, a special foil with a heat-sensitive layer on the surface. The source document is printed on this paper using a common black print, which is then heated by an infra-red lamp in a special device called “fuser”. During the heat treatment the graphics grows in volume, it raises above the surface of the paper and creates a smooth relief, easy to be read by touch.
