3D printed maps will enable the blind to navigate their city

3d maps

3D printed map.

While modern technology has benefited most of us by turning the things we consume from physical object into pixels on a screen, those with sight difficulties don’t get along well with visual stimuli or touchscreen devices. We have seen Yahoo! Japan develop Hands On Search, a project that lets blind kids carry out web searches with 3D printed results. Now the country’s governmental department GSI is creating software that will enable those with visual impairments to print out 3D versions of online maps.

The official mapping body for Japan — much like the US Geological Survey — GSI already has paper maps for the blind, using embossed surfaces to mark out roads. It’s now developing a program that is able to do the same thing for digital maps.

The software first differentiates the highways, railway lines and walkways from the rest of the landscape. It then creates a 3D relief model that uses different textures to distinguish the features so that anyone running their finger along them will be able to determine what it is. The program also takes into account contour lines, creating accurate topographical representations of a particular area.

GSI has already processed the data for urban locations at a scale of 1:2500, as well as rural areas at 1:25000. Although users will need access to a 3D printer in order to create their own physical maps, the body believes the technology is becoming more and more affordable and especially holds value for those with sight difficulties. Are there other ways to intelligently replicate digital data in physical form for the visually impaired?
