Blind graphic

from Wikipedia, the free encyclopedia
In front of us is a slanted metal panel framed in wood on the right and left. As a tactile and visible relief, it shows the cross section of a mountain, which is crossed by a 2700 meter long water-bearing tunnel. This leads from the higher Urftsee on the left side of the mountain to the right on the other side to a valve house; then it goes, from there on again above ground, down a steep gradient to a power station on the river Rur. The lettering on the information board is in raised normal font as well as in Braille. A longer explanatory text in German is also available in normal and Braille. This text is also available in English, Dutch and French, but not in Braille in these languages. A round metallic plaque on the wooden frame bears the number 3 in Arabic and Braille; this table is evidently the third of several stations.
Graphic representation as a tactile relief with explanations in Braille of the course of the Kermeter tunnel from Urftsee under the Kermeter (500 m) to a hydroelectric power station.

A tactile graphic is for blind palpable human form of a fact graphically illustrated. Graphics for the blind are used wherever a textual description in Braille would not be sufficient or would not be easy enough.

Graphics for the blind in publications for the blind can be produced using the embossing process or using special tactile inks in inkjet printers . Embossed metal panels are used in public spaces. Braille graphics are combined with braille.
