Pharos

Abstract

Landmark-based navigation systems have proven benefits relative to traditional turn-by-turn systems that use street names and distances. 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, municipal 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 confidently and build a more accurate mental map of the navigated area than using turn-by-turn instructions.

Design and evaluation of radiation disaster prevention map based on evacuation behavior

“…This result also verified that landmarks were easier to perceive than other spatial objects and had obvious advantages [ 9 , [43] , [44] , [45] ], and it is recommended that evacuation assembly points should be located close to the landmark, the landmark acts as a spatial reference point. This helps people locate, orient, and navigate faster in complex space environments during emergency evacuation [ [46] , [47] , [48] , [49] , [50] ].…”

Spatial Knowledge Acquisition for Pedestrian Navigation: A Comparative Study between Smartphones and AR Glasses

“…Moreover, GPS users traveled more slowly, made larger direction errors, drew sketch maps with poorer topological accuracy, and rated wayfinding tasks as more difficult than direct-experience participants. In another study [32], the authors proposed a novel system for pedestrian navigation assistance that included global landmarks (for example, the Eiffel Tower) in navigation instructions. They found a better performance, as compared to turn-by-turn navigation systems, in terms of navigating the environment and building a more accurate mental map.…”

Location based services: ongoing evolution and research agenda

“…In terms of interface technologies and devices, smartphones are not the only mobile client in LBS. More and more mobile and wearable devices are introduced for LBS applications (Figure 3), such as smartwatches (Wenig et al 2017), digital glasses (e.g. Google Glasses and Epson Moverio BT-200) (Rehman and Cao 2017), mobile projectors (e.g.…”
