Relief Pictures for the Blind
While visiting an excellent exhibition of large-scale photographs called 'Earth from the Air" by Yann Arthus-Bertrand, I notice an interesting new idea related somewhat to relief sculptures.
To help the blind appreciate the spectacluar photographs as well as the messages they convey, they also display Braille text descriptions next to a number of smaller photographs converted into suitable relief pictures. The idea is that visually handicapped visitors can also enjoy the exhibition through tactile finger 'reading' of the texts as well as the photographs.
I show below one example showing an aerial photo of Sao Paulo (or is it Rio de Janeiro?), Brazil, and the tall sculpture of Jesus on the hill top.
It requires special scanning and etching technologies to convert these 2-D photos into suitable tactile relief photos. See link.
I understand it also requires good understanding of what type of relief is suitable for the tactile feeling of the fingers, see link.
