A visible corner-landmark based route finding algorithm for pedestrian navigation

Although many GPS-based pedestrian navigations are released, their instructions at decision points are not sufficient. This is mainly due to the lack of landmark informations. They may cause pedestrians to pass decision points or misunderstand when to turn. This paper proposes a visible corner-landmark based route finding algorithm. The proposed algorithm is based on visibility edges for landmarks and can obtain a pedestrian route that has visible landmarks on its corner points. Experiments demonstrate that the proposed algorithm can maximize the visible corner landmarks included in the generated routes.
