Krzywicka-Blum, E., Kuchmister, J.: New Way in Cartography for the Blind: Sonic Coding of Contour Lines. Kartografické listy, 2000, 8, 7 figs., 3 refs.

Abstract: This paper presents the results of sonic method of coding shapes using the sonic digitizer. The instrument has been made as original author’s solution. The succession of sounds representing object are decoded during sequential orthogonaly oriented motion inside the operational area composed of two (A4) parts.

Keywords: maps for blind users, sonic digitizer
