However, one obstacle to the implementation of landmark-based navigation systems is the complex challenge of selecting salient local landmarks at each decision point for each user. In this paper, we present Pharos, a novel system that extends turn-by-turn navigation instructions using a single global landmark (e.g. the Eiffel Tower, the Burj Khalifa, mu- nicipal TV towers) rather than multiple, hard-to-select local landmarks. We first show that our approach is feasible in a large number of cities around the world through the use of computer vision to select global landmarks. We then present the results of a study demonstrating that by including global landmarks in navigation instructions, users navigate more con- fidently and build a more accurate mental map of the navigated area than using turn-by-turn instructions.13deGlobal LandmarksLandmark-based NavigationComputer VisionSmartwatchesPedestrian Navigation500Pharos: Improving Navigation Instructions on Smartwatches by Including Global LandmarksKonferenzbeitragurn:nbn:de:gbv:46-00106433-11
