Abstract

Presentation of graphical information is very important for blind. This information will help blind better understand surrounding world. The developed system is devoted for investigation of graphical information by blind user using a digitiser. SVG language with additional elements is used for describing of maps. Non-speech sounds are used to transfer information about colour. Alerting sound signal is issued near two regions boundary.
