Academic Track Paper

Today’s smartphones are more than just a telephone. With built-in positions sensors a phone can be used as a personal navigation device. Even blind or visual impaired people are used to modern phones. With assisted technologies like VoiceOver or Talkback, blind people aren’t reliant on phones with haptic/touchable keys. A lot of effort was made to improve the positioning indoor and outdoors, but affordable technologies are not accurate enough to navigate blind persons on a safe trip. The positioning should be improved by telling the user the surrounding environment. In example the user can verify the position of the sidewalk by telling him the location of the street and the buildings. The goal is the selection of a routing maschine which can deliver a safe route and additional trip information (i.e. crossings with acoustic traffic lights).
