New Trends in Non-visual Interaction - Sonification of Maps

  • Vidas Lauruska
Part of the Lecture Notes in Computer Science book series (LNCS, volume 6766)


An inexpensive sonification system of maps and charts for visually impaired is described. A digitiser (tablet) is used as system’s input device, which helps to investigate the map. The maps are presented using xml technology – mainly svg language tags. Then the maps from svg are converted to RGB bitmap. A system software is based on Microsoft .NET technology. Free Microsoft development systems as Visual C# 2008 Express Edition and Direct Sound are used to implement sonification system.
