Researchers in Japan have recently released new software which would allow visually-impaired people to print off a 3D map of various regions or areas. The maps, which use raised ridges to highlight roads, railways and other notable features, come from the Geospatial Information Authority, the government department responsible for mapping and geographical data. The maps use a scale of 1:2500 (1cm on the map is equal to 25m) for urban areas and 1:25000 (1cm is equal to 250m) for rural areas. The hope is for these maps is that, besides offering a greater level of independence, they could be used as life-saving pieces of equipment in emergencies, helping the user navigate to safety during evacuations which may occur due to earthquakes and tsunamis.

Presently, however, there are a number of restrictions on the new technology. While more common in Japan, the 3D printers required for making the maps are still prohibitively expensive in most places and it is unlikely that this will become a mainstay for the majority of visually-impaired people in the immediate future. However, if 3D printers do become more mainstream and affordable the technology for this will undoubtedly become more accessible and could become a more common aid for the visually impaired. The makers may also be over optimistic in their hopes for the maps’ usability, particularly in emergencies, as an unfamiliarity with the terrain, as well as the overall difficulties most people have with map reading in good circumstances, may make it harder to use than anticipated. The idea is definitely there though and it also demonstrates the great potential the growth and abilities of 3D printers offers in creating technology and equipment which can aid and improve the lives of people with disabilities.
