Navigating Within the Urban Environment Using Location and Orientation-Based Services

… Navigation Conference and …, 2006

Up to now most attempts to develop pedestrian navigation tools for the urban environment have used GPS technologies to display position on two-dimensional digital maps (as in the classic 'satnav' systems on the market). Although GPS is the key technology for location-based services (LBS), it cannot currently meet all the requirements for navigation in urban environments. Specifically, GPS technologies suffer from multipath signal degradation and they cannot provide orientation information at low or zero speed, which is an essential component of navigation. It has also been demonstrated in research that maps are not always the most effective interfaces to pedestrian navigation applications on mobile devices. This paper will explore solutions to the orientation and interface challenges in pedestrian navigation on mobile devices. Orientation information is necessary to help the user self-localise in an unknown environment and can be provided by calibrated digital compass integrated with the GPS positioning. Further orientation assistance can be provided by computer-vision techniques by detecting features included in the navigation route. These can be either user-predefined fiducials or a careful selection of features belonging into the real world (i.e. parts of buildings). With the combination of position and orientation it is possible to design augmented reality interfaces, which offer a richer cognitive experience and which, deliver orientation information infinitely and without the limitations of maps. Augmented reality is a collection of technologies with the aim of enhancing the real environment with digital information. The paper will be illustrated with applications and case studies from the LOCUS project forming part of the UK Pinpoint Faraday Initiative (now succeeded by the Location and Timing Knowledge Transfer Network).

Pedestrian navigation system in mixed indoor/outdoor environment–the NAVIO project

2004

Pedestrians have often ways in unfamiliar urban environment or in complex buildings. In these cases they need guidance to reach their targets, for example a specific room in a local authorities' building, a counter, or an institute at an university. The goal of location-based mobile services is to provide such guidance on demand (anywhere, anytime), individually tailored to the actual information needs and presented in preferred forms. This project is focusing on the information aspect of location-based services, i.e., on the user's task at hand and the support of the user's decisions by information provided by such a service. Specifying a task ontology will yield context-dependent conceptualizations, activities, and references to directions from the user's perspective. These specifications will allow to:

Use and Perceptions of Pedestrian Navigation Apps: Findings from Bologna and Porto

ISPRS International Journal of Geo-Information

Pedestrian Navigation Applications (PNAs) provide assistance in terms of self-localization, space recognition, and turn-by-turn navigation. The use, motivations and perceptions associated with these applications have been under investigated due to users being insufficiently involved in their design and development. This paper analyses the extent to which PNAs are used for assisting people to walk, the frequencies and reasons of using these applications, the perceptions about them, and the barriers preventing them from being used. The study is supported by a questionnaire (N = 1438) that was administered in Bologna (Italy) and Porto (Portugal). Results indicated that 42% of the respondents use PNAs mainly on an occasional basis to find locations and the shortest routes. Google Maps was the preferred navigation service. Statistical tests showed that PNAs were more likely to be used by younger adults and students. The lack of need was the main reason for not using these apps, due to th...

Personal mobile navigation systems—design considerations and experiences

Computers & Graphics, 2001

Every business or salesman knows the problem of a fast orientation on an unknown area like a fairground or an exhibition. For instance the CeBIT2000 represents the worldwide biggest computer fair with approx. 8200 exhibitors in an area of more than 400,000 m 2 . The exhibitors are ...

Performance Evaluation of Pedestrian Locations Based on Contemporary Smartphones

International Journal of Navigation and Observation, 2017

Nowadays, a Global Navigation Satellite System (GNSS) unit is embedded in nearly every smartphone. This unit allows a smartphone to detect the user’s location and motion, and it makes functions, such as navigation, tracking, and compass applications, available to the user. Therefore, the GNSS unit has become one of the most important features in modern smartphones. However, because most smartphones incorporate relatively low-cost GNSS chips, their localization accuracy varies depending on the number of accessible GNSS satellites, and it is highly dependent on environmental factors that cause interference such as forests and buildings. This research evaluated the performance of the GNSS units inside two different models of smartphones in determining pedestrian locations in different environments. The results indicate that the overall performances of the two devices were related directly to the environment, type of smartphone/GNSS chipset, and the application used to collect the infor...
