Abstract
Abstract. Car navigation system devices provide today with an easy and simple solution to the basic concept of reaching a destination. Although these systems usually achieve this goal, they still deliver a limited and poor sequence of instructions that do not consider the human nature of using landmarks during wayfinding. This research paper addresses the concept of enriching navigation route instructions by adding supplementary route information in the form of landmarks. We aim at using a contributed source of landmarks information, which is easy to access, available, show high update rate, and have a large scale of information. For this, Wikipedia was chosen, since it represents the world’s largest free encyclopaedia that includes information about many spatial entities. A survey and classification of available landmarks is implemented, coupled with ranking algorithms based on the entries’ categories and attributes. These are aimed at retrieving the most relevant landmark information required that are valuable for the enrichment of a specific navigation route. The paper will present this methodology, together with examples and results, showing the feasibility of using this concept and its potential of enriching navigation processes.
Highlights
Nowadays, with the increasing use of GNSS (Global Navigation Satellite System) in various applications, many people use automated navigation software to assist them with getting directions
To handle the topic of "what is a good route direction", we need to understand and separate between three different aspects: 1) how can one asses the quality of a good route direction: what aids the user to navigate successfully in a cognitive manner; 2) what criteria interest the user while using the navigating system: distance, time, or other-interest; and, 3) how to collect and what sources to use for delivering with comprehensive set of valuable and instructive information, so the system can construct the most complete and useful navigation process
Recent research and studies show that the human mind can be distracted while driving and listening to the verbal route instructions or concentrating on the map that appear on the system’s screen (Hipp et al, 2010). Such that the navigators do not pay attention to their immediate surrounding environment. This means that the users do not construct a cognitive process during the navigation process; consecutively, they do not create a mental map of their area of interaction – a process that is immediate in case of navigating with a map and using landmarks for wayfinding
Summary
With the increasing use of GNSS (Global Navigation Satellite System) in various applications, many people use automated navigation software to assist them with getting directions These systems are mostly capable of dealing with giving route directions from point A (origin) to point B (destination), by giving a relatively small and simple set of instructions, which are mainly based on turn by turn navigation directions. Recent research and studies show that the human mind can be distracted while driving and listening to the verbal route instructions or concentrating on the map that appear on the system’s screen (Hipp et al, 2010) Such that the navigators do not pay attention to their immediate surrounding environment. Questions related to what is a valuable landmark that contributes to the overall objective, and to what immediate available data sources exist for this purpose need to be addressed
