Efficiently Using Bitmap Floorplans for Indoor Navigation on Mobile Phones
Pedestrian navigation applications and especially indoor navigation applications need to describe a way in a form that is easy to understand, remember and follow. While in the case of outdoor vehicle navigation the distance in meter together with a turn hint is a good description such a description is merely useless for the indoor area. Pedestrians do not have a good understanding of distances and turns are not always well-defined in the indoor area. Landmarks seem to bring the solution to this problem. With this paper, the authors define an algorithm to identify relevant landmarks and a general algorithm enhancing the visualisation quality of an indoor way using bitmap floor-plans.
