Towards Automatically Generated Tactile Detail Maps by 3D Printers for Blind Persons

This paper introduces an approach for the (semi)automatic generation of worldwide available, detailed tactile maps including buildings and blind-specific features based on recognized illustrators’ guidelines and standards. These guidelines for tactile maps are investigated in order to define a formal rule set and to automatically filter map data accordingly. Using the rule set, our approach automatically abstracts map data in order to generate a 2.1D tactile model providing multiple height levels (layers) which can be printed by usual consumer 3D printers. Based on the popular OpenStreetMap map data, our automated approach allows to generate arbitrary detail maps blind persons individually interested in, without the need for manual adaption of the tactile map. Thus, this approach contributes to the goal to increase the autonomy of blind persons.
