Blind Friendly Maps

Abstract : Space concept of the surrounding area is one of the most important preconditions of the independent mobility and orientation of the blind people. Tactile maps are considered to be the most appropriate source of spatial information. One of the main problems of the tactile maps usage is their problematic accessibility for the blind users since they are not available in time and with up-to-date content. The map production is a matter of tedious manual work and a result of expensive and time-consuming technical methods. After several years of joint effort of the support centers at Czech Technical University in Prague and Masaryk University in Brno, and in cooperation with company (an operator of the map portal), the blind people have opportunity to use free available tactile maps of the entire Czech Republic (see with the highest possible zoom). Using the Mapnik toolkit, source vector map data are automatically converted to special maps, which can be downloaded and printed on a microcapsule paper so they become readable by touch. The whole country is displayed on map sheets in a single scale (approximately 1:1500, which corresponds to the area of 300 × 425 meters per sheet), with a single map key and with an integrated system of the description. Street names are abbreviated and displayed in the Braille code. Technology of the microcapsule (swell) paper was selected as the most accessible technology for tactile graphics in Czech Republic (at schools and support centers for the visually impaired). Our method opens new perspectives of tactile maps usage because detailed tactile maps of a selected territory are available in a few minutes and they are updated in the same mode and from the same source data as all other web maps at the portal. Even web maps may now be "blind friendly".
