Abstract

An inexpensive sonification system of maps and charts for visually impaired is described. A digitiser (tablet) is used as systems 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 implememt sonification system.
