Abstract

The novel prototype application of the system supporting the street navigation and independent, outdoor movement of the blind is presented. The system is capable of finding the route from the indicated source to chosen destination, using dedicated digital map and a set of various sensors. Subsequently, the system supports the movement of the blind along the found route. The user's position is obtained with the use of DGPS receiver. In order to further improve accuracy, particle filtering method is used. The system operates on a casual smartphone and communicates with the blind by the touch screen and by the voice messages generated by speech synthesizer.
