The SyWA app is a navigation utility dedicated to blind people, and allows these people to reach, by walking, the set destination point, providing vocal indications relating to turns and the presence of points along the route, inserted in a server. The destination points can be chosen by explicitly writing the desired street or by selecting points belonging to certain types, for example pharmacies, bus stops, etc. The app also manages points identified by the presence of BLE Tags, installed in places of particular interest, such as shops. Initial versions of the app may implement only some of the features.
