Abstract (en)
[origin: WO2015149890A1] The present invention discloses a method for pathfinding in a building, wherein a user of a mobile terminal uses a plurality of navigation points installed in the building to determine a path to a desired destination in the building. The pathfinding is effected using the principle of next-hop forwarding in routing protocols. In the case of such packet switching, a packet switcher does not know the complete path to the destination of the data packet, but only the route to the next intermediate station or " next hop". The collected path descriptions that are required at a respective position for successful navigation are short enough to be able to be recorded in the memory of a navigation point, for example a Bluetooth beacon. For successful indoor navigation, a short textual path description at the next respective fork in the path or distinctive location is sufficient to allow a user to find the path. Accurate position finding or geometric location is advantageously unnecessary to this end.
