Abstract: An electronic device can provide an interactive map with non-visual output, thereby making the map accessible to visually impaired users. The map can be based on a starting location defined based on a current location of the electronic device or on a location entered by the user. Nearby paths, nearby points of interest, or directions from the starting location to an ending location can be identified via audio output. Users can touch a screen of the electronic device in order to virtually explore a neighborhood. A user can be alerted when he is moving along or straying from a path, approaching an intersection or point of interest, or changing terrains. Thus, the user can familiarize himself with city-level spatial relationships without needing to physically explore unfamiliar surroundings.
